[MW:7984] Percentage for N.D.T.

Sirs
Could you tell me where to find the percentage for N.D.T. using ASME B31-3 for example.
If working on a project where there is no client specification which states the percentages but working to ASME where would I find the percentage for radiography for example, I have seen an old ANSI Specification which did include the percentages but to my knowledge not in ASME.
If there is no guide lines for N.D.T. percentage in ASME then is there any way to calculate using pressure, material and the chemical which the pipe will be used for. 
 
Best Regards
 
John
