Annex A (normative) Test method for the resistance of valves
        to operating loads (see 5.1.4)
Annex B (normative) Torque requirements for gate valves to be
        operated by ring key and bar (see 5.2.3 and Annex A)
Annex C (normative) Test method for the operation of valves
        (see 5.2.3)
Annex D (normative) Test method for the endurance of valves
        (see 5.5)

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