by endorsement, at the latest by February 2004, and conflicting national standards shall be withdrawn at the latest

by Feburary 2004.
This document supersedes EN 246:1989.

In respect to potential adverse effects on the quality of water intended for human consumption, caused by the

product covered by this standard, it should be noted that, while awaiting the adoption of verifiable European

criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.

This European Standard specifies:

the dimensional, mechanical, hydraulic and acoustic characteristics with which flow rate regulators should

comply;
the procedures for testing these characteristics.
This European Standard is applicable to:

flow rate regulators intended to be mounted on tapware used with sanitary appliances in toilets, washrooms

and kitchens (single taps, combination tap assemblies, mechanical mixing valves, thermostatic mixing valves);

flow rate regulators used under the following pressure and temperature conditions:

Table 1 – Conditions for the use of flow rate regulators
Limits of use Recommended limits for correct
operation
Dynamic Pressure 0,05 MPa £ P £ 0,5 MPa 0,1 MPa £ P £ 0,5 MPa
(0,5 bar £ P £ 5 bar) (1 bar £ P £ 5 bar)
Temperature £ 70 °C £ 65 °C

Flow rate regulators can only be connected downstream of the obturator of the tap.

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.
