This standard specifies magnetic particle testing methods to determine surface discontinuity D acceptance boundary as required by the purchaser, when testing procedures are specified in the contract.
This standard is applicable to the magnetic particle testing for ferromagnetic steel castings produced with various casting methods.
When magnetic intensity is 2.4 KA/m, the steel is ferromagnetic steel if its magnetic induction is greater than 1T.
Note: as all non-destructive testing methods, this standard constitutes part of the general evaluation or particular evaluation specified in the contract.
