| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. TEST CONFIGURATION AND LOAD SETUP | |||
| A1 | Load distribution and centering in car Acceptance: Load centered in car; distributed uniformly; no hanging loads; test weights certified | Cl. 15.2 — Load must be evenly distributed | OK NC NA HOLD |
| A2 | Calibration of load measurement equipment Acceptance: Load cells/scale certified; within ±2% accuracy; certificate valid and current | Cl. 15.2 — Accurate measurement required | OK NC NA HOLD |
| B. RATED LOAD TEST (100% CAPACITY) | |||
| B1 | Load = Rated Capacity; travel upward from pit bottom Acceptance: Load mass = rated capacity (±2%); smooth upward motion; no jerking; completion time within ±10% of design | Cl. 15.2 — Test with 100% rated load | OK NC NA HOLD |
| B2 | Load = Rated Capacity; travel downward to pit Acceptance: Smooth descent; brake engagement smooth; arrival velocity controlled; no excessive noise | Cl. 15.2 — Test descent with rated load | OK NC NA HOLD |
| B3 | Speed stability at rated load Acceptance: Actual speed within ±2% of rated speed; measured using speedometer or tachometer | Cl. 15.2 — Speed must remain stable | OK NC NA HOLD |
| B4 | Brake holding torque with rated load Acceptance: Car held on brake without motion; no drift for 60 seconds at each floor; brake pressure stable | Cl. 15.2 — Brake must hold safely | OK NC NA HOLD |
| C. OVERLOAD TEST (125% CAPACITY) | |||
| C1 | Load = 125% Rated Capacity; short travel test Acceptance: Load mass = 1.25 × rated capacity; car rises ≥ 1.0 m minimum; motor current ≤ 130% rated; no damage observed | Cl. 15.2 — Overload safety verification | OK NC NA HOLD |
| C2 | Overload protection activation Acceptance: Car stops rising at limit; alarm activates; doors lock; load held securely on brake | Cl. 15.2 — Overload limit must trigger | OK NC NA HOLD |
