BS ISO 4986:2010 Steel castings. Magnetic particle inspection

BS ISO 4986 specifies a method for the magnetic particle inspection of ferro-magnetic steel castings.

It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present.

BS ISO 4986 applies to all ferro-magnetic castings, independent of the moulding method.

A steel 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.

BS ISO 4986 only applies to those areas of the castings specified for inspection, as well as the percentage of castings to be inspected
