标准范围

本国际标准规定了在以下条件下测试管道组件抗弯曲疲劳性能的方法压力。该方法适用于聚乙烯(PE)分接头三通、PE/金属过渡配件和PE分支鞍座，适用于公称外径de u 63 mm的PE管。注:试验是基于模拟埋地管网实际产生的应力，即组合弯曲和拉伸应力。通过放大实践中观察到的位移来加速测试。

This International Standard specifies a method for testing the flexural fatigue resistance of piping assemblies underpressure.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 u 63 mm.NOTE The test is based on simulating the stresses generated in practice on buried piping networks, i.e. combined bendingand tensile stresses, at ambient temperature. The test is accelerated by magnifying the displacements observed in practice.
