Annex A (normative) Test method for the resistance to
                    internal pressure of the shell and of all
                    pressure containing components (see 5.1.1)
Annex B (normative) Test methods for the resistance of the
                    obturator to differential pressure (see
                    5.1.2)
Annex C (normative) Test method for the resistance of valves
                    to bending (see 5.1.3)
Annex D (normative) Minimal test method for the leak-
                    tightness to external pressure of the
                    shell and all pressure containing
                    components (see 5.2.1.2)
Annex E (normative) Test method for the resistance to
                    disinfection products (see 5.4)

Defines the minimum fitness for purpose requirements for valves to be connected to, or used in water supply pipe systems, either above or below ground, carrying water for human consumption. Establishes general performance and design requirements, and the conformity assessment procedure for valves, whatever their type and materials.

This European Standard defines the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems, above or below ground (see EN 805), carrying water intended for human consumption.

This standard specifies the general design requirements, the performance requirements and the conformity assessment method for valves, whatever their type and materials.

This standard deals with the requirements that are common to several types of valves; it is applicable only when quoted as reference in one of the other parts of this standard.
