1 Scope
This Standard specifies a testing method for determining the acceptance limits of surface discontinuities detected by penetrant testing, when such a testing procedure has been contractually agreed upon at the request of the purchaser.
This Standard applies to all steel castings, whatever casting process is used.
Note: It should be remembered that penetrant testing, like all methods of non-destructive testing, forms part of an overall or special assessment which is defined in the contract.
