Scope
This International Standard specifies a method for checking the leaktightness 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 leaktightness 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.
