| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. VISUAL LEAKAGE INSPECTION | |||
| A1 | System pressurized to test pressure (1.5 × design pressure); pressure held steady for 30 minutes minimum Acceptance: Test pressure maintained throughout, gauge stable reading, no pressure drops >0.1 bar | Cl. 13.1 — Pressure holding | OK NC NA HOLD |
| A2 | All visible joints and fittings inspected for water seepage; inspection done every 5 minutes during test Acceptance: Visual inspection at 5-min intervals, dry surface at all joints, no water droplets or streams | Cl. 13.2 — Periodic inspection | OK NC NA HOLD |
| A3 | If seepage observed at any joint: test FAILED; joint location marked, system depressurized, repair initiated Acceptance: Leaking joint isolated, repaired (retightened/re-solvent/re-seal), re-tested individually before main system re-test | Cl. 13.3 — Failure response | OK NC NA HOLD |
| A4 | After 30 minutes: zero visible leakage = PASS; full test report prepared with photos if available Acceptance: No seepage at any location, system passes, test certificate issued and signed by QC engineer | Cl. 13.4 — Acceptance | OK NC NA HOLD |
| B. LEAKAGE DOCUMENTATION | |||
| B1 | All test readings recorded in table: Time, Pressure (bar), Observations (any seepage location) Acceptance: Readings tabulated every 5 minutes, locations of any seepage noted with dimensions/identifiers | Cl. 14.1 — Record keeping | OK NC NA HOLD |
| B2 | Final verdict: PASS (zero leakage) or FAIL (seepage detected) with location/extent documented Acceptance: Pass/Fail clearly stated, leakage location (if any) marked on drawing, remedial action documented | Cl. 14.2 — Final verdict | OK NC NA HOLD |
