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