聚乙烯管材和管件 拉申强度的测定和熔接对接接头试件的失效模型

[中文适用范围]： 本国际标准描述了测定对接熔融聚乙烯（PE）管道组件的拉伸强度和拉伸破坏模式的测试方法。 本方法适用于公称外径不小于90mm的PE管之间的对接熔接接头。 该方法可以与其他测试方法一起使用来评估对接熔接接头的质量。 [外文原描述]： This International Standard describes a test method for determination of the tensile strength and tensile failure mode of butt-fused polyethylene (PE) pipe assemblies. The method is applicable to butt-fused joints between PE pipes with a nominal outside diameter of not less than 90mm. . The method may be used, together with other test methods, to evaluate the quality of the butt-fused joints.
