Specifies the test needed to confirm the ability of hand-operated plastics valves to withstand prolonged use, with repeated closure and openings. Does not specify the ability of valves to withstand adverse conditions; particularly those of chemically aggressive fluid media and/or environments, or excessive fluid velocities and cavitation. Includes values of parameters necessary for the proper performance of the endurance test (although parameters may be different in particular product standards).
