This document specifies general construction, performance and material requirements for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, elderly and disabled persons, the mixed water temperature needs to be set at a suitable bathing temperature (body temperature approximately 38 °C) as children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children during bathing. It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilets and cloakrooms) and bath rooms operating under the conditions specified in Table 1. This document allows TMVs to supply a single outlet or a small number of outlets in a "domestic" application (e.g. one valve controlling a shower, bath, basin and/or bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use). The tests described are type tests (laboratory tests) and not quality control tests carried out during manufacture.

This document applies 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 applies in the following pressure and temperature conditions: Table 1 — Conditions of use for tapware Dynamic Pressure range recommended for a good working Urinals WC DN 15 WC DN 20 0,1 MPa ≤ P ≤ 0,5 MPa (1 bar ≤ P ≤ 5 bar) WC DN 25 0,08 MPa ≤ P ≤ 0,25 MPa (0,8 bar ≤ P ≤ 2,5 bar) WC DN 32 0,08 MPa ≤ P ≤ 0,25 MPa (0,8 bar ≤ P ≤ 2,5 bar) Maximum static pressure 1 MPa (10 bar) Water temperature ≤ 25 °C NOTE 1 Although this document limits the pressure for WC DN 25 and WC DN 32 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.
