EN 12516 Inspection & Test Plan (ITP)
A typical stage-wise ITP / quality plan for valves supplied to EN 12516 — 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 EN 12516 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 EN 12516 (Industrial Valves - Shell Design Strength); 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 EN 12516
- Part 1 (EN 12516-1): Wall thickness tables for common valve materials (steel, stainless steel) vs pressure-temperature class
- Part 2 (EN 12516-2): Analytical calculation method for non-standard geometries and materials
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 EN 12516 / 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 pressure test per EN 12266-1 (industrial valve testing standard): 1.5× rated pressure, 2 minutes minimum
- Seat leakage test per EN 12266-1, leak rate class A/B/C/D per EN 1267
- Prototype pressure test to burst (EN 12516-3) if calculation method not applied
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- Design calculation report per EN 12516-2 or wall thickness compliance table per EN 12516-1
- Declaration of Conformity to EN 12516 and PED 2014/68/EU (for CE-marked valves)
- EN 10204 3.1 material test certificates confirming actual Rm/Rp0.2 properties
- CE Technical File including design calculations, test records, and quality documentation
Final documentation review before release/dispatch.
This is a typical ITP framework populated from EN 12516 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.
