3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply:
flow rate regulator
A device which is fitted on the nozzle outlet of a tap to enable its jet to be regulated
A distinction is made between:
flow rate regulators without air intake, when operating without aeration of the water;
flow rate regulators with air intake, when aeration of the water occurs;
ball joint flow rate regulators, when a flow rate regulator with or without aeration is fitted into a ball joint.
4 Designation
A flow rate regulator is designated by:
its type ; (with/without air intake)
its dimension (Q);
its acoustic group (I) and flow rate class (A);
reference to this standard.
Example of designation :
Flow rate regulator without air intake, with internal thread : M22X1; I; A – EN 246 (cf. Figure 1 and Table 2)
Flow rate regulator without air intake, with external thread : M28X1; I; A – EN 246 (cf. Figure 2 and Table 1)
5 Marking – Identification
Flow rate regulators complying with this standard shall be marked permanently and visible on their outer face with:
the mark or name of the manufacturer;
the acoustic group and the flow rate class.
The flow rate class shall be marked on the outer face of the skirt of the grille cage, if it is an interchangeable type
detachable changer
In order to distinguish flow rate regulators with air intake from flow rate regulators without air intake they shall also
be marked with an X on the exterior surface.
Ball joint flow rate regulator shall be marked both on the ball joint device and on the flow rate regulator.
6 Materials
6.1 Chemical and hygienic characteristics
All materials coming into contact with water intended for human consumption shall present no health risk up to
a temperature of 90 °C. They shall not cause any deterioration in water intended for human consumption, with
regard to food quality, appearance, odour or taste.
Within the recommended limits given in clause 1 for correct operation, the materials shall not be subject to any
deterioration which might affect the operation of the flow rate regulator. Pressurized parts shall withstand the limits
of use specified in Table 1. Materials with inadequate corrosion resistance shall be given additional protection.

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).

Sanitary tapware - Low pressure thermostatic mixing valves - General technical specification
SIST EN 1287:2017

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 - 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. toilet and cloakrooms) and bathrooms 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.
