This European Standard specifies, dimensions, materials and performance requirements (including methods of test) for combined temperature and pressure relief 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). Combined temperature an pressure relief valves are intended for fitting to storage water heaters, having a maximum distribution temperature of 95°C, for all energy sources.
