Plastics piping systems - Valves for polyethylene (PE) piping systems - Test method for leaktightness under and after bending applied to the operating mechanisms

This document specifies a test method for PE valves to maintain tightness during and after being subjected to a force, applied as a bending moment to the operating mechanism.Valves according to these standards are intended for use in polyethylene (PE) piping systems for the transport of fluids.When specified in the product document, this document can be applied to valves and plastics pipes of material different than PE.
