Fire protection — Automatic sprinkler systems — Part 2: Requirements and test methods for sprinkler system alarm valves, check valves, water motor alarms, retard devices and accelerators (ISO 6182-2:2025)
This document specifies performance, requirements, methods of test and marking requirements for the following equipment for use in automatic fire protection systems:
— wet alarm valves;
— retard devices;
— water motor alarms;
— dry pipe valves;
— accelerators;
— deluge valves;
— preaction valves;
— check valves.
Performance and test requirements for trim valves for alarm valves are not covered by this document.
The requirements for pressure reducing valves and fire pump relief valves are provided by ISO 6182-16 and ISO 6182-17.
