This ensures that any deformed metal does not interfere with the performance of the other tests methods for the Izod impact on metals

) which should generally be checked before the accuracy is tested

Plastics piping systems. Valves for polyethylene (PE) piping systems. Test method for leaktightness under and after bending applied to the operating mechanism has-digital Sensitive information: any information1 Scope This standard specifies a method for testing the ability of a valve, intended for use in polyethylene (PE) piping systems for gas supply, to maintain its pressure retaining capabilities under and after being subject to a bending moment applied to the operating mechanism (cap).
