标准摘要
[中文适用范围]： 本国际标准规定了管材环拉伸试验的方法，通过使试件承受应变直至发生断裂来揭示表面和内部缺陷。 该测试也可用于评估管的延展性。 环拉伸试验适用于外径超过150mm、壁厚不大于40mm的管材。 内径应大于100毫米。 [外文原描述]： ISO 8496:2013 specifies a method for a ring tensile test of tubes to reveal surface and internal defects by subjecting the test piece to strain until fracture occurs. This test may also be used to assess the ductility of tubes. The ring tensile test is applicable to tubes having an outside diameter exceeding 150 mm and a wall thickness no greater than 40 mm. The inside diameter shall be greater than 100 mm.
