DESCRIPTION

BS EN 15091:2013


This standard BS EN 15091:2013 Sanitary tapware. Electronic opening and closing sanitary tapware is classified in these ICS categories:
  • 91.140.70 Sanitary installations

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

The conditions of use for the supply system type are specified in Table 2:

Table 2 — Conditions of use

Water supply system Limits of use Recommended limits of operation
Tapware with normally open or normally closed (monostable) solenoid valves Tapware with latching (bistable) solenoid valves Tapware with normally open or normally closed (monostable) solenoid valves Tapware with latching (bistable) solenoid valves
Type 1 (see Figure 1) Minimum dynamic pressure 0,05 MPa (0,5 bar) 0,05 MPa (0,5 bar) (0,1 to 0,5) MPa [(1 to 5) bar] (0,1 to 0,5) MPa [(1 to 5) bar]
Maximum static pressure 1 MPa (10 bar) 1 MPa (10 bar) 1 MPa (10 bar) 0.8 MPa (8 bar)
Type 2 a (see Figure 2) Minimum dynamic pressure 0,01 MPa (0,1 bar) 0,01 MPa (0,1 bar) (0,01 to 0,2) MPa [(0,1 to 2) bar] (0,01 to 0,2) MPa [(0,1 to 2) bar]
Maximum static pressure 1 MPa (10 bar) 1 MPa (10 bar) 0.8 MPa (8 bar) 0.6 MPa (6 bar)
Temperature of the water ≤ 75 °C ≤ 75 °C ≤ 65 °C ≤ 65 °C

a For Type 2, the manufacturer is 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 recommended 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.

A vented domestic hot water and cold water supply system incorporating gravity hot water, mains cold water and alternative gravity cold water supply to sanitary appliances.
