Inspection & Test Plan

ISO 17292 Inspection & Test Plan (ITP)

A typical stage-wise ITP / quality plan for valves supplied to ISO 17292 — inspection activities, tests, acceptance references and verifying documents, with recommended hold, witness and review points for QC and third-party inspection.

What is the ITP for ISO 17292 valves?

An Inspection & Test Plan (ITP) sequences every check between raw material and dispatch, and assigns each an inspection level — Review (document check), Witness (inspector may attend), or Hold (work stops until released). The plan below is a typical ITP for valves built to ISO 17292 (ISO 17292 - Metal Ball Valves for Petroleum, Petrochemical and Allied Industries); the tests and documents are drawn directly from the standard's requirements. Use it to structure your QAP or coordinate third-party inspection.

Inspection level:ReviewWitnessHold

1. Documentation & design review

Review
  • Approval of drawings, datasheets and QAP against ISO 17292
  • Full-bore (full-port) and reduced-bore (reduced-port) designs covered
  • Pressure-temperature ratings per ASME B16.34 or EN 1092-1 / ASME B16.5 flanges

2. Raw material verification

Review
  • Material Test Reports (MTRs) review per EN 10204 3.1/3.2
  • Positive Material Identification (PMI) of pressure-containing parts

3. Dimensional inspection

Witness
  • Dimensional check per ISO 17292 / ASME B16.34 / applicable face-to-face
  • Wall thickness verification

4. NDE (as applicable)

Witness
  • Visual, and RT/UT/MPI/DPT of castings/welds per specification

5. Pressure & performance testing

Hold
  • Shell hydrostatic test 1.5× rated pressure
  • Seat test at rated pressure bidirectional
  • Optional fire test to ISO 10497

Primary hold point — witnessed shell, seat and backseat tests.

6. Fire-type test (qualification)

Hold
  • Fire test per API 607 / API 6FA with post-fire leakage acceptance

7. Marking, painting & preservation

Review
  • Nameplate & body marking verification
  • Painting/coating DFT check, end protection and preservation

8. Final documentation

Hold
  • ISO 17292 compliance certificate
  • Hydrostatic test report
  • EN 10204 3.1 MTCs

Final documentation review before release/dispatch.

This is a typical ITP framework populated from ISO 17292 requirements, for reference. The actual hold/witness/review split is agreed per project between purchaser, manufacturer and the third-party inspection agency in the approved QAP. Confirm project-specific requirements before use.
