Revised Standard from Last Update.

1. SCOPE

1.1 This standard deals with the acceptance standard for discontinuities at or near the surface, detected by magnetic particle inspection for steel castings. The procedure adopted for this examination is as specified in IS 3703.

1.2 A steel shall be considered to be magnetic if the magnetic induction is greater than 1 tesla for a magnetic field equal to 2.4 kA/m. This standard does not apply to the testing of nonmagnetic or feebly magnetic material such as austenitic steel.
