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.
