ISO 9001 Inspection & Test Plan (ITP)
A typical stage-wise ITP / quality plan for valves supplied to ISO 9001 — 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 9001 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 9001 (Quality Management Systems - Requirements); 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 9001
- Context of the organisation: documented understanding of internal/external issues affecting quality
- Leadership: top management commitment and quality policy
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 9001 / 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- Calibrated test equipment for hydrostatic and pneumatic testing (traceable to national measurement standards)
- Dimensional inspection records using calibrated gauges, micrometers, and CMM
- Material verification records matching mill certificates to physical products
- Non-conforming product identification, segregation, and disposition records
Primary hold point — witnessed shell, seat and backseat tests.
6. Marking, painting & preservation
Review- Nameplate & body marking verification
- Painting/coating DFT check, end protection and preservation
7. Final documentation
Hold- ISO 9001:2015 certificate from UKAS, DAkkS, NABCB, or equivalent IAF-accredited certification body
- Quality Management System manual (or documented procedures) available for customer audit
- Certificate scope must include valve design, manufacture, inspection, and testing
- Certificate must be current (valid) - verify expiry date against IAF/IQNET registry
Final documentation review before release/dispatch.
This is a typical ITP framework populated from ISO 9001 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.
