This Eruopean Standard applies to flushing valves for WCs and valves for urinalswith automatic hydraulic closure, intended for: -WC pans prEN 997; -urinals; -siphon action urinals. It does not apply to no-contact detection valves. It is intended to specify: -the marking, identification, physical-chemical, dimensio- nal leaktightness, pressure behaviour, hydraulic, mechanical endurance and acoustic characteristics to determine requirement for the atmospheric interrup- ters (air gaps) which shall form an integral part of WC and urinal flushing valves with automatic closure.
