ISO 9017:2017规定了试样的尺寸和进行断裂试验的程序，以获得有关内部缺陷类型、尺寸和分布的信息，如孔隙、裂纹、未熔合、未穿透和断裂表面上的固体夹杂物。 ISO 9017:2017适用于所有形式的产品中的金属材料，其接头由厚度大于或等于2 mm的任何熔焊工艺制成。

ISO 9017:2017 specifies the sizes of test specimen and the procedures for carrying out fracture tests in order to obtain information about types, sizes and distribution of internal imperfections such as porosities, cracks, lack of fusion, lack of penetration and solid inclusions on the fracture surface. ISO 9017:2017 applies to metallic materials in all forms of product with joints made by any fusion welding process with a thickness greater or equal to 2 mm.
