Building valves - Pressure safety valves - Tests and requirements

Scope

This European Standard specifies, dimensions, materials and performance requirements (including methods of test) for pressure safety valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Pressure safety valves are intended for fitting to the cold water supply of storage water heaters, having a maximum distribution temperature of 95°C, for all energy sources. Pressure safety valves do not control the temperature and alone do not constitute the protection required for storage waters heaters.
