ISO 3503:2015 Preview
Plastics piping systems -- Mechanical joints between fittings and pressure pipes -- Test method for leaktightness under internal pressure of assemblies subjected to bending
ISO 3503:2015 specifies a method for checking the leak tightness under internal pressure of assembled joints between mechanical fittings and plastic pressure pipes when subjected to bending. It defines the calculation method for the average bending radius and how to perform this bending.
Checking of the leak tightness under internal pressure is carried out in accordance with the method given in ISO 3458.
This test method is not applicable to fusion-welded joints.
