标准范围

ISO 17638:2016规定了通过磁粉检测检测铁磁性材料（包括热影响区）焊缝表面缺陷的技术。该技术适用于大多数焊接工艺和接头配置。附录a中描述了将提供更高或更低测试灵敏度的基本技术的变化。ISO 17638:2016未规定指示的验收水平。ISO 23278或产品或应用标准中提供了有关指示验收水平的更多信息。

ISO 17638:2016 specifies techniques for detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The techniques are suitable for most welding processes and joint configurations. Variations in the basic techniques that will provide a higher or lower test sensitivity are described in Annex A.ISO 17638:2016 does not specify acceptance levels of the indications. Further information on acceptance levels for indications may be found in ISO 23278 or in product or application standards.
