Testing & Commissioning

NFPA 13, 14, and 20 acceptance testing — hydrostatic test, flush test, and the fire pump acceptance test at churn, rated, and 150% of rated flow — plus commissioning documentation and the contractor's material and test certificate.

About this module

Module 14 covered installing a system correctly; this module covers proving it. It works through the hydrostatic test's two-hour hold requirement, why flush testing has to hit a minimum scouring velocity rather than just run for a set duration, the three specific points — churn, 100% of rated flow, and 150% of rated flow — a fire pump acceptance test checks against its certified curve, and the standpipe flow test performed at the hydraulically most remote hose connection.

It closes with the contractor's material and test certificate — the signed, durable record that converts a one-time witnessed test into a standing document — and how this module's commissioning baseline hands off directly into Module 16's ongoing NFPA 25 inspection, testing, and maintenance program.
