适用范围

This International Standard specifies a method for testing the flexural fatigue resistance of piping assemblies under pressure. The method is applicable to polyethylene (PE) tapping tees, PE/metal transition fittings and PE branch saddles, intended for use with PE pipes having a nominal outside diameter de ≤ 63 mm. NOTE The test is based on simulating the stresses generated in practice on buried piping networks, i.e. combined bending and tensile stresses, at ambient temperature. The test is accelerated by magnifying the displacements observed in practice.
