Overview
ISO 6182-2:2025 - Fire protection - Automatic sprinkler systems - Part 2 defines performance, test methods and marking requirements for key mechanical components used in automatic sprinkler systems. Published in 2025 (fourth edition), this international standard covers equipment including wet alarm valves, dry pipe valves, preaction and deluge valves, check valves, retard devices, water motor alarms and accelerators. It is part of the ISO 6182 series for sprinkler systems and replaces earlier editions.
Key topics and technical requirements
This standard focuses on practical, verifiable requirements rather than design guidance. Major technical topics include:
- Performance requirements: Functional performance criteria for alarm valves, check valves, retard chambers and related components.
- Test methods: Standardized laboratory tests for body strength, leakage, sealing assemblies, hydraulic friction loss, endurance, operational performance and equilibrium time.
- Material and ageing tests: Warm-water and air-ageing tests for non-metallic components, and salt-mist corrosion testing for exposed parts.
- Alarm and audibility: Requirements and tests for water motor alarms including durability and sound output.
- Manufacturing controls: Production testing, quality control procedures, and sampling requirements for production body strength and leakage tests.
- Marking and documentation: Mandatory marking information and manufacturer’s installation, care and maintenance instructions.
- Scope exclusions: Trim valves for alarm valves are not covered; pressure-reducing valves and fire pump relief valves are specified in ISO 6182-16 and ISO 6182-17.
Applications and who uses it
ISO 6182-2:2025 is essential for:
- Manufacturers of sprinkler system valves and water motor alarms to ensure compliance and to design products that meet international testing criteria.
- Testing laboratories and certification bodies that perform type and production tests.
- Fire protection engineers and specifiers who select components for system design and performance verification.
- Installers, maintenance teams and facility managers who rely on manufacturer markings and installation instructions for safe system operation.
- Authorities Having Jurisdiction (AHJs) and procurement teams that enforce compliance with internationally recognized fire protection standards.
Practical uses include product development, type approval, procurement specification, factory quality control and acceptance testing of installed sprinkler system components.
