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.
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.
