This standard specifies: - materials, surface coatings and finishes of the product. - dimensions, hydraulic characteristics, tightness and mechanical properties, which shall be fulfilled by the expansion valves. - tests to determine that the characteristics and properties are met. - marking and presentation for pressure safety valves of nominal sizes DN 15 to DN 40 and with working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar) for fitting to storage water heaters and heating circuits, with a distribution temperature not exceeding 95 °C for all energy sources. The pressure safety valve does not control the temperature and does not constitute alone the protection required for storage water heaters. It is not intended that it acts as a expansion valve under normal conditions.
