| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. TEST PROCEDURE & METHODOLOGY | |||
| A1 | Adhesion test method: Pull-off test (ASTM C1583) — tensile adhesion measurement Acceptance: Pull-off adhesion tester; 50mm diameter dolly; maximum loading 10 kN | Cl. 402 — Test standard | |
| B. TEST EXECUTION & RESULTS | |||
| B1 | Test point 1: Adhesion strength measured (N/mm²); failure mode noted (cohesive/adhesive) Acceptance: Minimum ≥0.5 N/mm² for waterproofing; ≥1.0 N/mm² preferred; cohesive failure preferred | Cl. 402 — Individual test result | |
| B2 | Test point 2: Adhesion strength measured; failure mode noted Acceptance: Minimum ≥0.5 N/mm²; cohesive failure (within coating or substrate) indicates good adhesion | Cl. 402 — Individual test result | |
| B3 | Test point 3: Adhesion strength measured; failure mode noted Acceptance: Minimum ≥0.5 N/mm²; consistent with previous results | Cl. 402 — Individual test result | |
| B4 | Average adhesion strength calculated; standard deviation noted; compliance assessed Acceptance: Average ≥0.5 N/mm²; standard deviation <0.2 N/mm² indicates consistent application | Cl. 402 — Statistical analysis | |
| C. FAILURE MODE ANALYSIS | |||
| C1 | Failure mode classification: Cohesive (in coating/substrate), Adhesive (interface), or Mixed Acceptance: Cohesive failure = good adhesion (preferred); Adhesive failure = poor adhesion (failure); Mixed acceptable | Cl. 402 — Failure assessment | |
