This document specifies a method for the magnetic particle testing of ferro-magnetic steel and iron castings.<\/p>\n
It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present.<\/p>\n
This document is applicable to all ferro-magnetic castings, independent of the moulding method.<\/p>\n
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.<\/p>\n
This document only applies to those areas of the castings specified for testing, as well as the percentage of castings to be tested.<\/p>\n
