| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. MAIN SUPPLY PRESSURE AND FLOW TEST | |||
| A1 | Static pressure at main inlet measured without flow Acceptance: Minimum ≥ 3.5 bar; measurement recorded with calibrated gauge; reading taken at stabilized state (≥ 30 seconds) | Cl. 4.1 — Baseline pressure measurement | OK NC NA HOLD |
| A2 | Hydrant #1 outlet flow measured at 3.5 bar minimum outlet pressure Acceptance: Flow ≥ 20 litres/minute; measured with calibrated flow meter or bucket method (30-second collection); pressure at outlet ≥ 2.8 bar | Cl. 4.2 — Hydrant flow rate | OK NC NA HOLD |
| A3 | Hydrant #2 outlet flow measured simultaneously (if 2-hydrant simultaneous operation required) Acceptance: Both hydrants flowing; total flow ≥ 40 litres/min combined; pressure at each outlet ≥ 2.5 bar (may drop with simultaneous draw) | Cl. 4.3 — Multiple hydrant operation | OK NC NA HOLD |
| A4 | Pressure drop measured along the system during flow (from inlet to farthest hydrant) Acceptance: Pressure drop < 1.0 bar for 20 m/min flow; indicates acceptable pipe sizing and friction losses | Cl. 4.4 — Pressure loss assessment | OK NC NA HOLD |
| B. HYDRANT OUTLET AND COUPLING TEST | |||
| B1 | Outlet dimension verified (38 mm standard coupling, ISO/Storz compatible) Acceptance: Outlet measured 38 mm ± 1 mm; standard fire department hose coupling fits smoothly; no leakage when connected | Cl. 5.1 — Coupling compatibility | OK NC NA HOLD |
| B2 | Nozzle/shut-off valve operation tested under flow and pressure conditions Acceptance: Nozzle closes smoothly with one-hand operation; no water spray when closed; open/close cycles ≥ 5 with smooth operation | Cl. 5.2 — Valve functionality | OK NC NA HOLD |
| B3 | Water leakage at outlet cap/closure when hydrant not in use Acceptance: No visible water dripping from outlet; cap seated firmly; gasket condition checked (replace if deteriorated) | Cl. 5.3 — Outlet sealing | OK NC NA HOLD |
| C. HOSE REEL OPERATION TEST | |||
| C1 | Hose reel rotation and extension tested; hose deploys smoothly without kinks or snagging Acceptance: Reel rotates without binding; hose extends fully without twisting; return mechanism functional (if spring-loaded) | Cl. 6.1 — Reel functionality | OK NC NA HOLD |
| C2 | Hose condition inspection: diameter, length, surface integrity checked for cracks/splits Acceptance: Hose 25-30 mm diameter; length ≥ 30 m; no visible cracks, splits, or hard spots; pressure-tested at 5 bar (visual only for this test) | Cl. 6.2 — Hose integrity | OK NC NA HOLD |
| C3 | Water spray pattern from nozzle verified (conical/straight stream adjustable if multi-pattern nozzle) Acceptance: Spray covers minimum 3 m² area at 5 m distance; uniform pattern with no dead spots; adjustment smooth | Cl. 6.3 — Spray pattern | OK NC NA HOLD |
