标准范围

ISO 9934-1:2016规定了铁磁性材料磁粉检测的一般原则。磁粉检测主要适用于检测表面断裂不连续性，尤其是裂纹。它还可以探测地表以下的不连续性，但其灵敏度随着深度的增加而迅速降低。ISO 9934-1:2016规定了待测零件的表面处理、磁化技术、检测介质的要求和应用，以及结果的记录和解释。验收标准没有定义。产品标准（见相关国际标准或欧洲标准）中规定了特定项目磁粉检测的附加要求。ISO 9934-1:2016不适用于剩余磁化法。

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.
