标准摘要
[中文适用范围]： 本文件规定了铁磁材料磁粉检测的一般原则。 磁粉检测主要是一种检测表面不均匀性，特别是裂纹的方法。 靠近表面也可以检测到不均匀性，但灵敏度随着深度的增加而迅速下降。 本文件规定了测试对象的表面处理、磁化技术、测试设备的要求和应用、指示登记和评估。 没有定义资格标准。 产品相关标准中规定了磁粉检测的附加要求。 本文件不适用于剩磁。 [外文原描述]： ISO 9934-1:2016 specifies general principles for the magnetic particle testing of ferromagnetic materials. Magnetic particle testing is primarily applicable to the detection of surface-breaking discontinuities, particularly cracks. It can also detect discontinuities just below the surface but its sensitivity diminishes rapidly with depth. ISO 9934-1:2016 specifies the surface preparation of the part to be tested, magnetization techniques, requirements and application of the detection media, and the recording and interpretation of results. Acceptance criteria are not defined. Additional requirements for the magnetic particle testing of particular items are defined in product standards (see the relevant International Standards or European standards). ISO 9934-1:2016 does not apply to the residual magnetization method.
