Introduction
This document is relevant for electrically operated (opening and closing) sanitary tapware used with
sanitary appliances, with a maximum voltage of 42 V AC / 72 V DC, in the enclosure of the tap.
Such tapware can be operated by any electrical source e.g. mains with a transformer, battery, etc.
Flow and temperature regulation devices installed either upstream or downstream of the tapware are
not covered by this specification.
The purpose of this document is to define requirements for the:
a) marking, identification, leak-tightness, electrical and operational safety, mechanical performance
and limitation of water hammer for electrical opening and closing tapware;
b) dimensional, hydraulic, endurance and acoustic characteristics;
c) procedure of tests in order to verify these characteristics.
As for possible unfavourable effects of the product to which this document applies, on the quality of water
intended for human consumption:
d) no information is provided by this document on possible use restrictions of the product in any of the
member states of the EU or EFTA;
e) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or characteristics of this product remain in force.
Requirements for different products are defined in different clauses of this document as illustrated in

1 Scope
The purpose of this document is to define requirements for marking, identification, leaktightness,
electrical and operational safety and mechanical resistance for sanitary tapware with opening and closing
controlled electronically.

For Type 2, the manufacturer is expected to declare the minimum operating pressure at which opening, closing
and the specified flow rate can be obtained.
There is usually no acoustic classification for tapware used in supply systems of Type 2 and no specifications
governing the level of noise emissions from these water installations. If supply pressures are such that excessive
noise is generated it is advised that pressure or flow regulators are fitted in the system. Or where practicable,
tapware conforming to the appropriate acoustic classification are used.
Annex B lists possible consequences of using a product outside its recommended operating range.
