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

Specifies the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems, above or below ground, carrying water intended for human consumption.
