This document is applicable to flushing valves for WCs and valves for urinals, with automatic hydraulic closure, intended for:
— WC pans EN 997;
— single flush urinals EN 13407;
— siphon acting urinals EN 13407.
It does not apply to no-contact detection valves.
It is intended to specify:
— marking and identification, physico-chemical, dimensional, leaktightness, pressure behaviour, hydraulic, mechanical endurance and acoustic characteristics of flushing valves for WCs and urinals with automatic closure;
— test methods used to verify these characteristics;
— and to determine requirements for the atmospheric interrupter which shall be an integral part of the WC flushing valve.
It is applicable in the following pressure and temperature conditions (see Table 1):
[Table 1 — Conditions of use for tapware]
NOTE Although this document limits the pressure for WC DN25 and WC DN32 valves till 0,25 MPa (2,5 bar), some European countries have legislation and recommendations for higher pressures.
Health and quality requirements in accordance to European and national legislation for final materials in contact with water intended for human consumption are not covered by this document.
