API SIRE flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Hold point (H)

A step in the inspection and test plan where work must stop; production cannot continue until the inspector completes the required surveillance and records acceptance.

Witness point (W)

A notification point where the supplier must inform the inspector before the activity, but the work may proceed without the inspector's physical presence if they do not attend.

Review point (R)

A documentation-only point where records are examined after the activity is complete; no physical surveillance attendance is needed and results are verified from the records.

Inspection and test plan

A document listing process steps, characteristics inspected, acceptance criteria, inspection methods, and hold, witness, or review designations for each manufacturing step.

Pre-inspection meeting purpose

Confirm scope, applicable specifications and revisions, ITP points, sub-supplier approvals, calibration status, personnel qualifications, and open nonconformances before production starts.

AQL sampling plan basis

Lot size and inspection level from ANSI/ASQ Z1.4 set the sample size; the acceptance number comes from the AQL, and tightened or reduced plans follow switching rules.

Calibration check at source

Confirm each measuring and test instrument has a current calibration label and a certificate traceable to a national standard, and that its range covers the characteristic measured.

Document revision check

Before inspection, the purchase order, drawing, specification, and procedure revisions must agree; conflicting revisions are resolved in writing before any product is accepted.

WPS and PQR relationship

A welding procedure specification is qualified by a procedure qualification record produced from a test coupon; the PQR supports the ranges of variables that the WPS may use.

Welder qualification continuity

Under ASME Section IX, a welder's qualification lapses if the process is not used for six months; the employer must keep continuity records or re-qualify the welder.

Heat number traceability

The mill heat number is transferred to each cut piece before cutting so that chemistry and mechanical properties stay linked to the finished component.

Material test report check

Verify that heat number, chemical composition, tensile properties, heat treatment condition, and specification grade on the MTR match the drawing and purchase order requirements.

Preheat and interpass control

Measure preheat and interpass temperature with a calibrated contact thermometer or temperature-indicating crayon before and during welding, and record values against WPS limits.

Radiograph density requirement

ASME Section V requires film density between 1.8 and 4.0 in the area of interest, measured with a densitometer, with IQI sensitivity demonstrated on each film.

Nonconformance report disposition

An NCR documents the deviation; disposition options are rework, repair, use-as-is, or reject, and use-as-is requires approval by the design authority rather than the supplier.

Low-stress stamping

Marking pressure-containing parts with shallow rounded-nose stamps or vibro-etch avoids notch-like stress raisers; hard stamping is limited to areas the specification permits.

Hydrostatic shell test pressure

API 598 sets shell test pressure at 1.5 times the valve pressure rating at 38 °C (100 °F), with no visible leakage permitted at any body joint or connection.

Seat leakage test pressure

API 598 seat tests use 1.1 times the pressure rating at 38 °C, with allowable leakage limits set by valve type and size rather than zero leakage for every design.

Pressure gauge range rule

ASME code requires the test gauge to be calibrated and its full-scale range to be at least 1.5 and no more than 4 times the intended test pressure.

Chloride limit for test water

Water used for hydrotesting austenitic stainless steel must have controlled chloride content, commonly 30 ppm maximum, and be drained and dried after the test.

Positive material identification

PMI by X-ray fluorescence or optical emission verifies alloy chemistry on critical components; API 578 governs the program, the sampling, and acceptance of results.

Pneumatic test hazard

Pneumatic testing stores far more energy than hydrostatic testing, so the code requires lower pressure ratios, remote gauges, barricades, and written approval before use.

Re-test after repair

Any repair or rework affecting the pressure-containing boundary requires the affected test to be repeated after repair, heat treatment, and NDE are complete.

Acceptance criteria source

Acceptance criteria come from the referencing code or specification, not from the NDE procedure; the procedure defines the technique and the code defines what is acceptable.

Certificate of conformity

A signed statement that the product meets purchase order and specification requirements, issued only after all hold points, tests, and nonconformances are closed.

Record retention requirement

API Q1 requires documented retention times for quality records; contracts often specify five years, and records must remain legible and retrievable for that period.

Document control basics

Only current revisions may be available at the point of use; obsolete documents are removed or marked, and changes are reviewed and approved before release.

Corrective action requirement

A corrective action addresses root cause rather than only the symptom; it includes containment, cause analysis, implementation, and verification that the problem does not recur.

Traceability record linkage

Heat numbers, serial numbers, and test report numbers must link the mill certificate, manufacturing records, and the finished item so any component can be traced back.

Inspector stop-work authority

The inspector may halt work when a documented nonconformance or specification violation is found; release then requires objective evidence of correction and acceptance.

API Q1 scope

API Q1 specifies quality management system requirements for organizations manufacturing equipment for the petroleum and natural gas industry and is used with API product specifications.

Inspection report content

A source inspection report identifies purchase order, item and serial or heat numbers, specification revision, date, activities witnessed, results, nonconformances, and the inspector's signature.
