Building valves. Hydraulic safety groups. Tests and requirements algolia-search-ignore Requirements for marking and information1 Scope This European Standard specifies dimensions, materials and performance requirements (including methods of test) for hydraulic safety groups, of nominal sizes from DN 15 to DN 25, having working pressures1) from 0,1 MPa (1 bar) to 0,7 MPa (7 bar). Hydraulic safety groups are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95C. Hydraulic safety groups limit the pressure in hot
