Question 1NBIC Overview

Under the National Board Inspection Code (NBIC), which organization is responsible for accrediting Authorized Inspection Agencies (AIAs)?

  1. The National Board of Boiler and Pressure Vessel Inspectors Correct answer.
  2. The manufacturer of the boiler or pressure vessel
  3. The jurisdiction where the item is installed
  4. The American Society of Mechanical Engineers (ASME)

Explanation

The NBIC assigns accreditation of Authorized Inspection Agencies to The National Board of Boiler and Pressure Vessel Inspectors. ASME develops the construction code but does not accredit AIAs. Jurisdictions may regulate installations, and manufacturers have no accreditation role for AIAs.

Question 2NBIC Overview

An Authorized Inspector Supervisor (AIS) is reviewing the scope of the NBIC. Which activity falls within the jurisdiction of the NBIC?

  1. In-service inspection of a boiler that is not under any jurisdictional regulation
  2. Welding procedure qualification for a new pressure vessel built to the ASME Code
  3. Repair of a pressure vessel by a holder of an ASME Certificate of Authorization Correct answer.
  4. New construction of a boiler performed entirely under the ASME Boiler and Pressure Vessel Code

Explanation

The NBIC covers in-service inspection, repairs, and alterations of boilers and pressure vessels, including repairs performed by ASME certificate holders. New construction and welding procedure qualification for new construction are governed by the ASME construction code, not the NBIC.

Question 3NBIC Overview

Which document does the NBIC require an Authorized Inspector to use as the basis for performing an in-service inspection of a boiler?

  1. The jurisdiction's boiler laws only
  2. The ASME Code Section I only
  3. The manufacturer's original construction drawings only
  4. The inspection plan developed by the AIA and accepted by the jurisdiction Correct answer.

Explanation

The NBIC requires in-service inspections to follow a written inspection plan prepared by the Authorized Inspection Agency and accepted by the jurisdiction. Construction drawings, jurisdiction laws alone, and ASME Section I alone do not constitute the required inspection plan.

Question 4NBIC Overview

An Authorized Inspector Supervisor is reviewing a repair to a pressure vessel. Under the NBIC, who may perform the repair?

  1. A holder of a valid National Board R Certificate of Authorization Correct answer.
  2. Any engineer employed by the jurisdiction
  3. Only the original manufacturer of the vessel
  4. Any welding contractor approved by the owner

Explanation

The NBIC requires repairs to be performed by a holder of a valid National Board R Certificate of Authorization. Owner-approved contractors, original manufacturers without an R Certificate, and jurisdictional engineers do not meet this requirement.

Question 5NBIC Overview

What is the primary role of the Authorized Inspector Supervisor in the NBIC inspection process?

  1. To establish the construction code requirements for new boilers
  2. To perform all in-service inspections personally
  3. To issue the Certificate of Authorization to the manufacturer
  4. To supervise and direct the inspection activities of Authorized Inspectors Correct answer.

Explanation

The AIS supervises and directs the inspection activities of Authorized Inspectors within the AIA. The AIS does not personally perform every inspection, does not issue certificates, and does not set construction code requirements.

Question 6NBIC Overview

An Authorized Inspector is assigned to inspect a boiler that has been altered. Which document must be completed and registered under the NBIC?

  1. An R-1 Form Correct answer.
  2. A new Manufacturer's Data Report
  3. A Certificate of Inspection
  4. An NB-1 Form

Explanation

Alterations under the NBIC are documented on an R-1 Form and registered with the National Board. Manufacturer's Data Reports and NB-1 Forms relate to new construction, and a Certificate of Inspection is not the alteration record.

Question 7NBIC Overview

Which of the following is a required qualification for an individual to be certified as an Authorized Inspector under the NBIC?

  1. Being employed by the jurisdiction's regulatory agency
  2. Having at least ten years of experience in boiler manufacturing
  3. Holding a valid National Board Commission Correct answer.
  4. Holding a professional engineering license in the jurisdiction

Explanation

The NBIC requires Authorized Inspectors to hold a valid National Board Commission. A PE license, ten years of manufacturing experience, or employment by the jurisdiction are not the NBIC qualification for an Authorized Inspector.

Question 8NBIC Overview

An Authorized Inspector discovers that a repair organization is working without a valid R Certificate. What is the most appropriate action for the Authorized Inspector Supervisor?

  1. Issue a temporary R Certificate to the organization
  2. Stop the repair work and require the organization to obtain a valid R Certificate before continuing Correct answer.
  3. Report the matter to ASME for enforcement action
  4. Allow the repair to continue if the owner provides written approval

Explanation

The NBIC requires repairs to be performed only by holders of a valid R Certificate; work by an uncertified organization must be stopped until certification is obtained. The AIS cannot issue certificates, owner approval does not cure the deficiency, and ASME does not enforce NBIC repair requirements.

Question 9NBIC Overview

Under the NBIC, what is the maximum period for which a Certificate of Authorization for a repair organization may be issued?

  1. One year
  2. Five years
  3. Three years Correct answer.
  4. Two years

Explanation

The NBIC provides that a Certificate of Authorization for a repair organization is issued for a maximum period of three years. One, two, and five years do not match the NBIC certification period.

Question 10NBIC Overview

Which of the following best describes the purpose of the NBIC according to its scope?

  1. To certify materials used in boiler construction
  2. To establish welding procedure specifications for new construction
  3. To provide rules for in-service inspection, repair, and alteration of boilers and pressure vessels Correct answer.
  4. To provide rules for the construction of new boilers and pressure vessels

Explanation

The NBIC provides rules for in-service inspection, repair, and alteration of boilers and pressure vessels. Construction rules, welding procedure specifications, and material certification for new construction are addressed by the ASME Code.

Question 11NBIC Overview

An Authorized Inspector Supervisor is reviewing the inspection records for a pressure vessel. Which record is required by the NBIC to be maintained by the Authorized Inspection Agency?

  1. The manufacturer's welding procedure qualification records
  2. The original mill test reports for all materials
  3. The inspection reports and records of inspections performed Correct answer.
  4. The design calculations for the pressure vessel

Explanation

The NBIC requires the Authorized Inspection Agency to maintain inspection reports and records of inspections performed. Mill test reports, welding procedure qualifications, and design calculations are construction records retained by the manufacturer.

Question 12NBIC Overview

What must an Authorized Inspector do before performing an in-service inspection of a boiler that has been repaired?

  1. Perform a hydrostatic test at 1.5 times the maximum allowable working pressure
  2. Verify that the repair was performed by an R Certificate holder and that the R-1 Form is complete Correct answer.
  3. Notify ASME of the repair
  4. Obtain a new Manufacturer's Data Report from the original manufacturer

Explanation

Before inspecting a repaired boiler, the Authorized Inspector must confirm that the repair organization held a valid R Certificate and that the R-1 Form is properly completed. A new Manufacturer's Data Report is not required, a hydrostatic test is not always required, and ASME is not notified of NBIC repairs.

Question 13NBIC Overview

Which entity is responsible for establishing the qualifications of an Authorized Inspector Supervisor under the NBIC?

  1. The National Board of Boiler and Pressure Vessel Inspectors Correct answer.
  2. The Authorized Inspection Agency employing the supervisor
  3. The American Society of Mechanical Engineers
  4. The jurisdiction where the AIA is located

Explanation

The National Board establishes the qualifications for Authorized Inspector Supervisors, including commission and experience requirements. ASME, the jurisdiction, and the employing AIA do not set these NBIC qualifications.

Question 14NBIC Overview

An Authorized Inspector Supervisor is evaluating whether a pressure vessel alteration requires an R-1 Form. Which criterion determines that an alteration has occurred under the NBIC?

  1. Routine maintenance that does not change the design
  2. Replacement of a non-pressure part such as a nameplate
  3. A change that affects the pressure-containing capability or the design temperature Correct answer.
  4. Any welding on the pressure vessel

Explanation

Under the NBIC, an alteration is a change that affects the pressure-containing capability or the design temperature of the item. Not all welding constitutes an alteration, and replacement of non-pressure parts or routine maintenance does not meet the alteration definition.

Question 15NBIC Overview

What is the required frequency for an internal inspection of a boiler under the NBIC, unless the jurisdiction specifies otherwise?

  1. Every three years
  2. Every five years
  3. Every two years
  4. Annually Correct answer.

Explanation

The NBIC generally requires an internal inspection of a boiler annually, unless the jurisdiction has established a different interval. Two, three, and five years do not reflect the NBIC default interval.

Question 16NBIC Overview

An Authorized Inspector Supervisor is reviewing a new construction project. Which document must the Authorized Inspector verify before applying the National Board registration number?

  1. The welding procedure specification only
  2. The jurisdiction's operating permit
  3. The manufacturer's ASME Certificate of Authorization and the Manufacturer's Data Report Correct answer.
  4. The owner's insurance policy

Explanation

Before National Board registration, the Authorized Inspector must verify that the manufacturer holds a valid ASME Certificate of Authorization and that the Manufacturer's Data Report is properly completed. Operating permits, insurance policies, and welding procedure specifications alone are not the basis for registration.

Question 17NBIC Overview

Which of the following is a responsibility of the Authorized Inspection Agency under the NBIC?

  1. Approving the manufacturer's quality control manual
  2. Issuing National Board commissions to inspectors
  3. Establishing the maximum allowable working pressure for new boilers
  4. Performing inspections and maintaining inspection records Correct answer.

Explanation

The AIA is responsible for performing inspections and maintaining the associated inspection records. National Board commissions are issued by the National Board, MAWP is established by the manufacturer per the construction code, and quality control manual approval is an ASME function.

Question 18NBIC Overview

An Authorized Inspector finds that a boiler has been operated beyond its maximum allowable working pressure. What action should the Authorized Inspector Supervisor direct?

  1. Notify ASME for a code interpretation
  2. Issue a new Certificate of Authorization to the owner
  3. Continue operation at the reduced pressure until the next scheduled inspection
  4. Require the boiler to be taken out of service until a thorough inspection and any necessary repairs are completed Correct answer.

Explanation

Operation beyond the maximum allowable working pressure may have caused damage, so the boiler must be removed from service until inspected and repaired as needed. Continuing operation, issuing certificates, or asking ASME for an interpretation does not address the safety concern.

Question 19NBIC Overview

Under the NBIC, what is the purpose of the National Board registration of a boiler or pressure vessel?

  1. To authorize the manufacturer to produce the item
  2. To establish the jurisdiction's operating requirements
  3. To provide a permanent record of the item's construction and inspection history Correct answer.
  4. To certify that the item meets the ASME construction code

Explanation

National Board registration creates a permanent record of the item's construction and inspection history. It does not certify ASME Code compliance, authorize manufacturing, or set jurisdictional operating requirements.

Question 20NBIC Overview

Which of the following activities is outside the scope of the NBIC?

  1. In-service inspection of a boiler
  2. Alteration of a pressure vessel
  3. Design of a new pressure vessel Correct answer.
  4. Repair of a pressure vessel

Explanation

The design of a new pressure vessel is governed by the ASME construction code and is outside the scope of the NBIC. In-service inspection, repair, and alteration are all activities covered by the NBIC.

Question 21NBIC Overview

An Authorized Inspector Supervisor is reviewing the qualifications of an individual proposed as an Authorized Inspector. Which requirement must the individual meet under the NBIC?

  1. Hold a valid National Board Commission and be employed by an AIA Correct answer.
  2. Be a licensed professional engineer in the jurisdiction
  3. Have completed an ASME welding certification course
  4. Have a minimum of five years of experience in boiler operation

Explanation

An Authorized Inspector must hold a valid National Board Commission and be employed by an Authorized Inspection Agency. Boiler operation experience, a PE license, and ASME welding certification are not the NBIC requirements for this role.

Question 22NBIC Overview

What is the role of the Authorized Inspector in the repair process under the NBIC?

  1. To perform the repair welding personally
  2. To approve the repair organization's quality control manual
  3. To review and accept the repair procedure and inspect the completed repair Correct answer.
  4. To issue the R-1 Form to the repair organization

Explanation

The Authorized Inspector reviews and accepts the repair procedure and inspects the completed repair for compliance with the NBIC. The inspector does not perform welding, does not issue the R-1 Form, and does not approve quality control manuals.

Question 23NBIC Overview

Under the NBIC, which document is required to be completed when a boiler is newly installed and registered with the National Board?

  1. NB-1 Form Correct answer.
  2. R-1 Form
  3. R-4 Form
  4. NB-2 Form

Explanation

The NB-1 Form is the Manufacturer's Data Report used for new construction and National Board registration of a boiler. The R-1 Form is used for repairs and alterations, and the R-4 and NB-2 forms serve other specific purposes.

Question 24NBIC Overview

An Authorized Inspector Supervisor is reviewing an inspection plan for a pressure vessel. Which element must the plan include according to the NBIC?

  1. The manufacturer's profit margin
  2. The owner's insurance carrier
  3. The welding procedure specification for original construction
  4. The method of inspection and the extent of examination Correct answer.

Explanation

The NBIC requires the inspection plan to specify the method of inspection and the extent of examination. Profit margin, insurance carrier, and original construction welding procedures are not elements of the inspection plan.

Question 25NBIC Overview

Which statement best describes the relationship between the NBIC and the ASME Boiler and Pressure Vessel Code?

  1. The NBIC supersedes the ASME Code for new construction
  2. The NBIC complements the ASME Code by providing rules for in-service inspection, repair, and alteration Correct answer.
  3. The NBIC and ASME Code are identical in scope
  4. The NBIC applies only to nuclear components

Explanation

The NBIC complements the ASME Code by addressing in-service inspection, repair, and alteration, while the ASME Code governs new construction. The NBIC does not supersede the ASME Code, is not identical in scope, and is not limited to nuclear components.

Question 26NBIC Overview

Under the NBIC, which body holds the copyright and issues the Code that Authorized Inspectors apply during in-service inspections?

  1. The American Society of Mechanical Engineers
  2. The National Board of Boiler and Pressure Vessel Inspectors Correct answer.
  3. The jurisdiction where the boiler is installed
  4. The authorized inspection agency

Explanation

The NBIC is developed, copyrighted, and published by The National Board of Boiler and Pressure Vessel Inspectors, which also certifies inspectors and registers objects. ASME publishes the construction Code, while jurisdictions adopt and enforce through their own statutes. The inspection agency employs inspectors but does not own the NBIC.

Question 27NBIC Overview

An Authorized Inspector Supervisor is orienting a new inspector to the NBIC structure. Which statement correctly describes how the NBIC treats new construction requirements?

  1. The NBIC applies only to repairs and does not address new construction at all
  2. The NBIC replaces ASME Section I for boilers once the boiler is placed in service
  3. The NBIC references the applicable ASME construction Code and adds administrative and stamping requirements Correct answer.
  4. The NBIC restates all ASME construction rules in full so no ASME Code is needed

Explanation

The NBIC incorporates by reference the applicable ASME construction Code for new construction and layers on National Board requirements such as stamps, data reports, and registration. It does not restate the detailed design and welding rules. This referencing approach keeps the in-service Code aligned with current construction standards.

Question 28NBIC Overview

A supervisor is asked which edition of the NBIC an Authorized Inspector should use for an inspection performed in a jurisdiction that has adopted the NBIC. What is the correct basis?

  1. The edition adopted by the jurisdiction exercising authority over the installation Correct answer.
  2. Any edition the authorized inspection agency selects by internal policy
  3. The edition in force on the date the boiler was originally constructed
  4. The most recent edition published, regardless of jurisdictional adoption

Explanation

The NBIC becomes enforceable through adoption by the jurisdiction, so the inspector follows the edition the jurisdiction has adopted. Agency policy cannot override the jurisdictional adoption. The construction date is relevant to the code of construction, not to which NBIC edition governs the inspection.

Question 29NBIC Overview

Which term does the NBIC use for the organization that employs Authorized Inspectors and holds a certificate from the National Board to perform inspections?

  1. Jurisdictional Authority
  2. Authorized Inspection Agency Correct answer.
  3. Owner-User Inspection Organization
  4. Repair Organization

Explanation

The Authorized Inspection Agency is the National Board-certified entity that employs Authorized Inspectors and provides inspection services. Repair organizations hold R Certificates for repairs, and owner-user organizations hold a different National Board certificate. The jurisdictional authority is the government body, not the inspection employer.

Question 30NBIC Overview

An Authorized Inspector Supervisor is reviewing a repair to a boiler and asks the inspector to identify the National Board form that documents the repair. Which form applies?

  1. R-1 Form Correct answer.
  2. R-4 Form
  3. NB-2 Form
  4. R-2 Form

Explanation

The R-1 Form is the Report of Repair used to document repairs and alterations performed under an R Certificate. The R-2 covers items other than pressure relief valves, and the R-4 addresses pressure relief device repairs. The NB-2 is a manufacturer's data report, not a repair report.

Question 31NBIC Overview

During a review, a supervisor notes that a pressure relief valve was repaired and reset. Which National Board form must document this work?

  1. R-2 Form
  2. NB-1 Form
  3. R-1 Form
  4. R-4 Form Correct answer.

Explanation

Repairs to pressure relief devices are documented on the R-4 Form, which records the valve repair and setting. The R-1 covers repairs to boilers and pressure vessels, and the R-2 covers items other than pressure relief valves. The NB-1 is a manufacturer's data report for new boilers.

Question 32NBIC Overview

An Authorized Inspector Supervisor is evaluating whether a proposed change to a pressure vessel constitutes an alteration under the NBIC. Which characteristic distinguishes an alteration from a repair?

  1. The work is completed during a scheduled shutdown
  2. The work requires welding of any kind
  3. The work is performed by the owner rather than a repair organization
  4. The work changes the pressure-retaining capability or the design of the item Correct answer.

Explanation

An alteration changes the item's design or pressure-retaining capability, whereas a repair restores the item to its original condition. Welding alone does not determine the classification, since many repairs involve welding. Who performs the work and when it is scheduled do not define an alteration.

Question 33NBIC Overview

Which qualification must an individual hold before being certified by the National Board as an Authorized Inspector?

  1. A National Board commission based on passing the required examination Correct answer.
  2. Membership in the jurisdictional boiler board
  3. A minimum of ten years of boiler operating experience
  4. A professional engineering license in the jurisdiction of employment

Explanation

An Authorized Inspector must hold a valid National Board commission, which is granted after meeting the qualification requirements and passing the National Board examination. A PE license, while valuable, is not the commission itself. Neither a fixed ten-year operating background nor board membership is the qualifying credential.

Question 34NBIC Overview

Under the NBIC, what is the primary purpose of the National Board registration of a boiler or pressure vessel?

  1. To create a permanent record of the item's construction data for future reference Correct answer.
  2. To transfer ownership of the item to the National Board
  3. To authorize the owner to operate the item at any pressure
  4. To certify that the item meets the current edition of the construction Code

Explanation

Registration creates a permanent National Board record of the item's data report and construction details, which supports future inspection and repair decisions. It does not certify Code compliance, transfer ownership, or set operating limits. Those functions belong to the inspector, the owner, and the jurisdiction.

Question 35NBIC Overview

An inspector finds a boiler operating with a relief valve set above the maximum allowable working pressure. Which action is most consistent with the NBIC?

  1. Recommend that the owner reduce the firing rate instead of correcting the valve
  2. Require correction of the condition and report it to the jurisdiction as required Correct answer.
  3. Adjust the relief valve setting personally to the correct value
  4. Record the finding and continue operation until the next scheduled inspection

Explanation

A relief valve set above the maximum allowable working pressure is a nonconforming condition that must be corrected and reported through the proper channels. The inspector does not personally adjust the valve, which is work for a qualified repair organization. Deferring correction or substituting a firing-rate change leaves the overpressure hazard in place.

Question 36NBIC Overview

An Authorized Inspector Supervisor is reviewing whether a new boiler installation requires National Board registration. Which document provides the construction data that supports registration?

  1. The jurisdictional operating permit
  2. The manufacturer's data report Correct answer.
  3. The inspection agency's internal log
  4. The R-1 Form

Explanation

The manufacturer's data report, such as the NB-1 for boilers, records the construction details that are registered with the National Board. The R-1 documents repairs, not new construction. Internal logs and operating permits are not construction records used for registration.

Question 37NBIC Overview

What is the relationship between the NBIC and the ASME Boiler and Pressure Vessel Code as applied by an Authorized Inspector?

  1. The NBIC governs in-service inspection and repairs while the ASME Code governs new construction Correct answer.
  2. The ASME Code governs in-service inspection while the NBIC governs new construction
  3. The NBIC supersedes the ASME Code for all purposes once a boiler is installed
  4. The two documents are identical in content and may be used interchangeably

Explanation

The ASME Code establishes construction requirements, and the NBIC addresses in-service inspection, repairs, and alterations while referencing the ASME Code for construction. The two documents are complementary rather than interchangeable. The NBIC does not supersede the ASME Code after installation.

Question 38NBIC Overview

An Authorized Inspector Supervisor is reviewing an inspection plan for an in-service pressure vessel. Which element must the plan identify to satisfy NBIC expectations?

  1. The purchase price of the vessel when new
  2. The name of the original welder who fabricated the vessel
  3. The name of the insurance carrier for the plant
  4. The scope and method of inspection, including the extent of examination Correct answer.

Explanation

An inspection plan must define the scope and methods of inspection, including the extent of examination needed to evaluate the vessel's condition. Fabricator welder names, purchase price, and insurance carrier details are not elements of the inspection scope. The plan should be specific enough to guide the inspector's work.

Question 39NBIC Overview

Which activity falls outside the scope of the NBIC?

  1. Review of a pressure vessel alteration
  2. Evaluation of an in-service pressure relief device
  3. Inspection of a boiler during a repair
  4. Design of a new pressure vessel to ASME Section VIII Correct answer.

Explanation

The design of new pressure vessels is governed by the ASME construction Code, not the NBIC. The NBIC addresses in-service inspection, repairs, alterations, and relief device evaluation. Design review for new construction belongs to the ASME Code and the manufacturer's quality program.

Question 40NBIC Overview

A supervisor is reviewing the frequency of internal boiler inspections. Which statement best reflects how the NBIC addresses this?

  1. The NBIC requires internal inspection only after a failure
  2. The NBIC sets one fixed interval that applies in every jurisdiction
  3. The NBIC prohibits internal inspection of boilers
  4. The NBIC provides requirements that may be modified by the jurisdictional authority Correct answer.

Explanation

The NBIC provides inspection requirements, but the jurisdictional authority may establish or modify intervals for the installations it regulates. The NBIC does not impose a single fixed interval everywhere. It certainly does not prohibit internal inspection or limit it to post-failure situations.

Question 41NBIC Overview

An Authorized Inspector discovers that a repair organization is performing repairs without a valid R Certificate. What is the most appropriate action for the inspector?

  1. Allow the work to continue and note the deficiency in the report
  2. Personally issue a temporary R Certificate to the organization
  3. Stop accepting the work and report the situation through proper channels Correct answer.
  4. Perform the repairs on behalf of the organization

Explanation

Work requiring an R Certificate cannot be accepted when the organization lacks one, so the inspector must withhold acceptance and report the situation. The inspector cannot issue certificates or perform the repairs. Allowing the work to continue would leave unqualified repairs in service.

Question 42NBIC Overview

Which statement best describes the role of the Authorized Inspector in the repair process under the NBIC?

  1. The inspector performs the repair and signs the R-1 Form
  2. The inspector sets the repair schedule and assigns the welders
  3. The inspector reviews and accepts the completed repair and signs the appropriate report Correct answer.
  4. The inspector approves the repair organization's business license

Explanation

The Authorized Inspector reviews the repair work, verifies compliance, and signs the applicable report to accept the completed repair. The inspector does not perform the repair, schedule the work, or assign welders. Those tasks belong to the repair organization.

Question 43NBIC Overview

An Authorized Inspector Supervisor is reviewing an inspector's decision to accept an alteration to a boiler. Which condition must be satisfied before the alteration is accepted?

  1. The alteration must be completed without welding
  2. The alteration must be documented on the appropriate form and supported by the required design information Correct answer.
  3. The alteration must reduce the maximum allowable working pressure
  4. The alteration must be approved by the insurance carrier alone

Explanation

An alteration must be documented on the appropriate National Board form and supported by design information demonstrating continued compliance. Welding is often part of an alteration and is not prohibited. Reducing the maximum allowable working pressure is not a requirement, and carrier approval alone does not satisfy the Code.

Question 44NBIC Overview

What is the purpose of the National Board commission held by an Authorized Inspector?

  1. It authorizes the holder to perform inspections under the NBIC Correct answer.
  2. It licenses the holder to design pressure vessels
  3. It authorizes the holder to perform repairs on boilers and pressure vessels
  4. It permits the holder to issue jurisdictional operating certificates

Explanation

The National Board commission authorizes the holder to perform inspections under the NBIC within the scope of the commission. It does not authorize repairs, design work, or the issuance of jurisdictional operating certificates. Those functions belong to repair organizations, designers, and the jurisdiction respectively.

Question 45NBIC Overview

An inspector is reviewing a pressure vessel that has been rerated to a higher maximum allowable working pressure. Which consideration is most important under the NBIC?

  1. The new rating requires only a new nameplate with no supporting analysis
  2. The new rating must be supported by an engineering analysis and documented as an alteration Correct answer.
  3. The new rating may be applied once the owner notifies the insurance carrier verbally
  4. The new rating is permitted if the vessel has operated without incident

Explanation

Increasing the maximum allowable working pressure changes the design basis, so it must be supported by an engineering analysis and documented as an alteration. Verbal notice, operating history, or a new nameplate alone cannot justify a higher rating. The documentation preserves the traceability required for future inspections.

Question 46NBIC Overview

Which of the following best describes how the NBIC treats owner-user inspection organizations?

  1. They are prohibited from performing any inspections under the NBIC
  2. They are automatically authorized to inspect any equipment in the jurisdiction
  3. They may be certified by the National Board to inspect their own equipment under defined conditions Correct answer.
  4. They replace the Authorized Inspection Agency for all purposes

Explanation

The NBIC provides for owner-user inspection organizations that may be certified by the National Board to inspect their own equipment under defined conditions. They are not prohibited, nor are they automatically authorized for all equipment. They do not replace the Authorized Inspection Agency across all purposes.

Question 47NBIC Overview

An Authorized Inspector Supervisor is reviewing an inspector's report and notices the inspector did not verify the item's National Board registration number. Why is this verification important?

  1. It proves the item is currently safe to operate
  2. It confirms the item's construction data are on file with the National Board Correct answer.
  3. It establishes the owner's insurance coverage limit
  4. It determines the inspection interval for the item

Explanation

Verifying the registration number confirms that the item's construction data are on file with the National Board, supporting traceability for future inspections and repairs. Registration does not prove current safety, set insurance limits, or determine inspection intervals. Those matters are handled through inspection findings, insurance, and jurisdictional rules.

Question 48NBIC Overview

Which statement correctly describes the National Board's role in relation to Authorized Inspector Supervisors?

  1. The National Board has no role in supervisor qualification
  2. The National Board delegates supervisor certification entirely to the jurisdiction
  3. The National Board certifies Authorized Inspector Supervisors and issues related credentials Correct answer.
  4. The National Board certifies supervisors only after ten years of service

Explanation

The National Board certifies Authorized Inspector Supervisors and issues the related credentials, building on the requirements for Authorized Inspectors. It does not delegate this entirely to jurisdictions or limit certification to a fixed service period. The National Board retains a direct role in qualification.

Question 49NBIC Overview

An inspector is asked to inspect a second-hand boiler that has been relocated from another jurisdiction. Which NBIC consideration is most relevant before the boiler is placed in service?

  1. The boiler's original data report is no longer relevant after relocation
  2. The boiler must be rebuilt to the current ASME Code edition
  3. The boiler may be placed in service without inspection because it was previously registered
  4. The boiler must be inspected and accepted under the requirements applicable in the new location Correct answer.

Explanation

A relocated boiler must be inspected and accepted under the requirements applicable where it will be installed, which may include jurisdictional requirements for second-hand equipment. Prior registration does not eliminate the need for inspection. The original data report remains relevant, and rebuilding to the current edition is not automatically required.

Question 50NBIC Overview

Which of the following is a required element of the Authorized Inspector's documentation when accepting an in-service inspection?

  1. A record of the inspection findings and the basis for acceptance Correct answer.
  2. A copy of the manufacturer's payroll records
  3. The original purchase order for the equipment
  4. A list of the owner's operating personnel

Explanation

The inspector's documentation must record the inspection findings and the basis for accepting the equipment. Payroll records, purchase orders, and personnel lists are not part of the inspection record. Clear documentation supports later reviews and regulatory reporting.
