1 Scope
This European Standard is applicable to single and mixer taps with automatic shut-off
for use with sanitary appliances installed in washrooms.
It does not apply to urinal or WC flushing valves or valves which open automatically.
The purpose of this standard is to specify the marking, identification, chemical/hygiene,
dimensional, leaktightness, pressure resistance, hydraulic, mechanical endurance,
and acoustical characteristics of automatic shut-off tapware.
The tests described in all the standard are type tests (laboratory tests) and not
quality control tests carried out during manufacture
The conditions of pressure and temperature given in Table 1 apply:

Conditions for the use of self-closing tapware
| Limits of use | Recommended limits of operation | |
|---|---|---|
| Dynamic pressure | 0,05 MPa (0,5 bar) min. | 0,1 MPa ≤ P ≤ 0,5 Mpa (1 bar ≤ P ≤ 5 bar) |
| Static pressure | 1 MPa (10 bar) max | − |
| Hot water temperature | Max ≤ 90 °C | 55 °C ≤ T ≤ 65 °C |
| Cold water temperature | - | T ≤ 25 °C |
(The pressures given are flow pressures)
