Standards Development

Scope

This European Standard specifies:

• definitions

• installation instructions

• requirements for test set-ups

• definitions for standard use cases and related actions for test parameters

• water flow rate, energy consumption per time unit

• rinsing performance or comfort

• water and energy efficiency

• the dimensional, leaktightness, pressure resistance, hydraulic performance, mechanical strength, endurance and acoustic characteristics with which taps, showers and shower systems shall comply. Furthermore, it specifies following product specific parameters, e. g.

• performance in function of the change of pressure;

• performance of water break;

• performance of cold start;

• performance of temperature break;

• difference between flow rate at highest and lowest water pressure;

• performance of thermostatic valve;

• performance of electronic tap;

• measurement of spreading area;

• measurement of spray force, where appropriate;

• performance of flow regulators;

• test methods in compliance with currently existing product standards for appliances of supply type 1 to verify the characteristics.

The tests described in this European Standard are type tests (laboratory tests) and not quality control tests carried out during manufacture.

This European Standard applies to PN 10 taps, for use with wash basins, kitchen and bidets.

This European Standard does not apply to shower taps for its own, since these products need to be used in combination with a shower outlet.

This European Standard does not apply to taps for filling bathtubs, or the tub filling function of combined taps since standard use cases require high flow rates and the water volume depends on the tub.

This European Standard applies to overhead and hand showers for connection downstream of the shut-off device of the sanitary appliance.

This European Standard applies to PN 10 shower systems, installed in rooms used for bodily hygiene (cloakrooms, bathrooms, etc.).

Purpose

Based on the European commission implementing decision of 16.12.2020, a standardisation request to the European Committee for Standardisation as regards the measurement of functional performance of taps and showers in support of Directive 2009/ 125/ EC of the European Parliament and of the Council and Regulation (EU) 2017/ 1369 of the European Parliament and of the Council has been submitted.

The standard shall support the application of potential measures for the implementation of Directive 2009/ 125/ EC and Regulation (EU) 2017/ 1369 to improve the environmental performance of taps and showers on the Union Internal Market.

The standard shall provide detailed measurement and calculation methods of parameters corresponding to the functional performance of taps and showers. The parameters concerned should include, among other possible parameters, the rinsing performance and users’ comfort as well as energy and water efficiency. They shall also reflect the generally acknowledged state of the art measurement and calculation methods. In this regard, existing standards on sanitary tapware shall be considered. The standard shall in particular ensure the necessary balance between the objectives of rinsing performance and users’ comfort, and of energy and water efficiency.
