(Amendment)

Sanitary tapware - Thermostatic mixing valves (PN 10) - General technical specification

Sanitary tapware - Thermostatic mixing valves (PN 10) - General technical specification

This European Standard 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 standard 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 is currently submitted to the CEN Enquiry.

1 Modification to Subclause 13.2.2.1
Replace entire subclause:
"The measurement is made at the maximum available flow rate going from cold to hot and then from
hot to cold. For the measurement a TMV, as supplied, or the outlet pipework, as defined in A.3, is used.
If the TMV is equipped with water saving accessories or aerators not complying with the flow rates
specified in EN 246, the flow rate test and acoustic test shall be made with the mixing valve as delivered
by the manufacturer.
Single sequential valves shall be adjusted to be able to attain a maximum 44 °C. Starting at full cold (off)
slowly adjust to 44 °C and then return to 34 °C.
Other device control systems (e.g. push-buttons, touch screens, etc.) shall be tested by a method that
ensures the correlation between outlet temperature and flow rate can be suitably recorded. The
procedure is subject to agreement between manufacturer and test laboratory."

Sanitary tapware - General specifications for aerators
SIST EN 246:2022

This document specifies:
- the dimensional, mechanical, hydraulic and acoustic characteristics with which sanitary tapware aerators (with and without flow regulation) should comply;
- the procedures for testing these characteristics.
This document is applicable to:
- Sanitary tapware aerators intended to be mounted on tapware used with sanitary appliances in toilets, bathrooms and kitchens (e.g. single taps, combination tap assemblies, mechanical mixing valves, thermostatic mixing valves);
- Sanitary tapware aerators used under the following pressure and temperature conditions (see Table 1).
[Table 1: Conditions for the use of aerators]
NOTE 1   Sanitary tapware aerators can only be connected downstream of the obturator of the sanitary tapware product.
NOTE 2   For the purposes of brevity, sanitary tapware aerators will be detailed only as aerators in the rest of this document.
NOTE 3   The tests described in this document are type tests (laboratory tests) and not quality control tests carried out during manufacture.
NOTE 4   Aerator swivels are to be tested in combination with a specific aerator only and are therefore considered to be sanitary tapware accessories. (Testing of the stand-alone swivels is therefore not covered by the scope of this document. Where swivels are used they are considered to be part of the tapware constructions, e.g. for bidet taps).
