Abstract

Overview

ISO 6182-4:2019 - Fire protection - Automatic sprinkler systems - Part 4: Requirements and test methods for quick opening devices - specifies performance and test requirements for accelerators (quick-opening devices) used with dry pipe valves. The standard ensures these devices reliably hasten valve operation when one or more sprinklers operate, improving response time in dry-pipe sprinkler systems.

Key topics and technical requirements

Scope and definitions: Defines accelerator, antiflooding device, holding chamber, rated working pressure and service pressure.
Rated working pressure: Minimum rated working pressure is 1.2 MPa (12 bar).
Leakage tests:
- Pneumatic leak test: 0.7 MPa for 1 minute (no leakage).
- Hydrostatic leak test: 2× rated working pressure for 5 minutes (no leakage).
Strength tests: All parts must withstand 4× rated working pressure for 5 minutes without permanent distortion.
Component durability: Springs and diaphragms must survive 5 000 cycles of normal operation (≤ 6 cycles/min). Sealing elements must show no damage after operational tests.
Materials and construction: Bodies/covers require corrosion resistance at least equivalent to cast iron; non-metallic body parts limited (no plastics with melting point
