本文件规定了铁磁钢和铁铸件的磁粉检测方法。 它还通过不连续性的性质、面积和尺寸定义的严重程度给出了验收标准。 本文件适用于所有铁磁铸件，与成型方法无关。 如果磁场强度为2.4 kA/m时，磁感应大于1 T（特斯拉），则认为钢和铁铸件具有铁磁性。 本文件仅适用于指定用于测试的铸件区域，以及待测试铸件的百分比。

This document specifies a method for the magnetic particle testing of ferro-magnetic steel and iron castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. This document is applicable to all ferro-magnetic castings, independent of the moulding method. A steel and iron casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T (Tesla) for a magnetic field strength of 2,4 kA/m. This document only applies to those areas of the castings specified for testing, as well as the percentage of castings to be tested.
