| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. TEST PROCEDURE | |||
| A1 | Upper manhole sealed; lower manhole filled with water to top (or design level) Acceptance: Water level at top of pipe, maintained for 30 minutes observation | Cl. 10.1 — Filling procedure | |
| A2 | Visual inspection for seepage from joints, pipe walls, or manhole connection points Acceptance: No water seeping from pipe joints, no weeping from manhole walls, dry downstream | Cl. 10.2 — Leakage detection | |
| B. ACCEPTANCE & VERDICT | |||
| B1 | PASS: Zero seepage observed; water level drop ≤1% per 100m length acceptable Acceptance: Drop ≤0.01m per 100m (or <5mm total for typical 500m section), test certificate issued | Cl. 10.3 — Pass condition | |
| B2 | FAIL: If seepage observed, location marked, repair made, and section re-tested Acceptance: Leaking pipe replaced or joint sealed, re-test confirms zero leakage | Cl. 10.4 — Failure response | |
