This draft European standard specifies: - the field of application; - the requirements for pressurised air inlet valves with non polymeric bodies; - the dimensional and the physico-chemical properties and the properties of general hydraulic, mechanical and acoustic design to which pressurised air inlet valves of nominal sizes DN 15 up to and including DN 50; - the family L, type A; - the family L, type B; - the test procedure and requirements for verifying these properties. For combined devices 1) only the anti-pollution tests are to be performed; - the marking and the presentation; - the acoustics; - this draft specifies the characteristics of pressurised air inlet valves of nominal size DN 15 up to and including DN 50 that are suitable for use in drinking water systems at pressures up to an including 1 000 kPa (10 bar) and temperatures up to and including 65 °C and for 1 h at 90 °C.
