Action taken by the National Board to temporarily or permanently withdraw an organization's accreditation when it fails to maintain required quality control or code compliance.

Work that restores a pressure-retaining item to a condition suitable for safe operation without changing its original design parameters, such as weld buildup or replacement of a damaged area.

A change to a pressure-retaining item that affects its pressure-retaining capability or changes design parameters such as pressure rating, temperature rating, or service limitations.

The Manufacturer's Data Report for repairs or alterations, documenting the item, the work performed, the code basis, and the certifications of the organization and inspector.

The Owner's Data Report used to record the owner's acceptance and the operating history relevant to a repair or alteration performed under the NBIC.

The data report used to document the repair or alteration of a pressure relief device, capturing device details, set pressure, and the work performed.

A qualified individual holding a National Board commission who performs the required inspections and certifications for repairs and alterations, including signing data reports.

The credential issued by the National Board to an individual who has demonstrated the required knowledge and experience to perform authorized inspections.

A stage in the repair or alteration process at which work must stop and inspection or approval must occur before proceeding, as defined in the quality control manual.

A step in the work sequence at which the inspector may observe the activity but the work is not required to pause before continuing.

A documented sequence of welding steps, including preparation, filler selection, preheat, and post-weld heat treatment, used to restore a pressure-retaining item.

A record demonstrating that a welding procedure specification has been tested and produces joints meeting the required mechanical properties.

Documented evidence that an individual welder has demonstrated the skill to produce acceptable welds for the specific process and position being used.

A controlled heating and cooling operation applied after welding to relieve residual stresses and reduce hardness in the repaired area.

Documentation of the time, temperature, and method used during post-weld heat treatment, retained as part of the repair quality records.

A device such as a safety valve or rupture disk that protects equipment from overpressure and is subject to specific repair and data reporting requirements.

The inlet pressure at which a pressure relief device is adjusted to begin opening, verified and documented when the device is repaired.

A written program describing an organization's policies, responsibilities, and procedures for controlling repairs and alterations, submitted for review during accreditation.

The overall structure of responsibilities, procedures, and resources an organization uses to ensure repairs and alterations consistently meet code requirements.

A condition in which work, material, or documentation fails to meet a specified requirement, requiring documented disposition before the item is accepted.

Steps taken to eliminate the cause of a detected nonconformance so that it does not recur, with records maintained as part of the quality program.

Documents such as data reports, inspection results, and test records that provide evidence of compliance and must be retained for the required period.

The process of verifying that inspectors, welders, and other personnel possess the training, experience, and credentials required for their assigned tasks.

The periodic comparison of measuring and test equipment against known standards to confirm accuracy within acceptable tolerances, with records retained.

The ability to trace materials used in a repair back to their specification, heat number, and certification, ensuring the correct material was installed.

A modification to the configuration or parameters of a pressure-retaining item that may constitute an alteration and require revised calculations and documentation.

The entity responsible for the operation of the equipment and for accepting the completed repair or alteration, often documented on the Owner's Data Report.

The process of submitting required data reports to the National Board so that repairs and alterations are recorded in the centralized database.

An identifier assigned to a registered item, allowing its repair and alteration history to be tracked in National Board records.

The required routing of completed data reports to the owner, the inspector, and the National Board, ensuring each party retains the appropriate record.
