标准摘要
[中文适用范围]： 本文件规定了通过磁粉探伤检测铁磁焊缝表面缺陷（包括热影响区）的技术。 这些技术适用于大多数焊接工艺和连接类型。 附录 A 中描述了这些基本技术具有更高或更低测试灵敏度的变化。 本文件并未对广告设定任何可接受性限制。 有关适应症可接受限值的更多信息，请参阅 ISO 23278 或产品或应用标准。 [外文原描述]： 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.
