EN 1092-1 Inspection & Test Plan (ITP)
A typical stage-wise ITP / quality plan for valves supplied to EN 1092-1 — 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 1092-1 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 1092-1 (Flanges and Their Joints - Circular Flanges for Pipes, Valves, Fittings and Accessories, PN Designated - Part 1: Steel Flanges); 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 1092-1
- PN (Pressure Nominal) designations from PN 6 through PN 400 - each with defined P-T rating by material group
- Flange type designations: Type 01 (plate, flat face), Type 02 (loose plate), Type 05 (blind), Type 11 (weld neck), Type 12 (hubbed slip-on), Type 13 (hubbed threaded), Type 21 (integral), Type 34 (welding boss)
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 1092-1 / 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- Dimensional inspection of flange face, bolt circle, and outer diameter per EN 1092-1 tables
- Shell hydrostatic test per manufacturer standard or PED requirements
- Material verification: PMI or 3.1 MTR for alloy and stainless steel flanges
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- EN 1092-1 dimensional compliance marking on flange
- CE Declaration of Conformity under PED 2014/68/EU (for EU supply)
- Material Test Report (MTR) per EN 10204 3.1
- Dimensional inspection report
Final documentation review before release/dispatch.
This is a typical ITP framework populated from EN 1092-1 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.
