Abstract

Overview - ISO 6182-6:2020 (check valves for automatic sprinkler systems)

ISO 6182-6:2020 is the international standard that specifies performance, requirements, test methods and marking for check valves used to supply water in automatic fire protection sprinkler systems. It applies to check valves (not trim valves) installed in the main waterway of sprinkler installations to prevent backflow and to help manage multiple pumps or flow-switch arrangements. Key takeaways: minimum nominal size DN25, rated working pressure ≥ 1.2 MPa (12 bar), and comprehensive mechanical, hydraulic and ageing tests.

Key topics and technical requirements

Scope and applicability
- Check valves for automatic sprinkler systems; not applicable to trim valves.
Nominal sizes & connections
- Valve sizes ≥ DN25; connections must meet the rated working pressure and relevant international/national standards.
Rated working pressure
- Minimum specified: 1.2 MPa (12 bar); manufacturer must specify rated working pressure.
Materials and construction
- Bodies and covers: materials with corrosion resistance at least equivalent to cast iron.
- Cover fasteners: steel, stainless steel, titanium or equivalent.
- Non-metallic body parts restricted; melting point of metals
