Re: [MW:22905] Excess penetration measurment in Radiograph

Yes, I agree with your Radiography image, but ASME B 31.3 acceptance criteria is only for Visual Inspection not for

Radiography image, moreover ball passing test is not specified in ASME standard,

Any idea about  Image Contrast graph method, Shell DEP has specified this test procedure for measuring Excess penetration,

Hi,

My opinion, in DWSI superimpose, you can see the excess penetration clearly. Please refer the attached image.

Please refer table 341.3.2 for acceptance criteria. However as Mr. Jerald mentioned earlier you can go for ball passing test to confirm the ID.

what is acceptance criteria for excess penetration as per ASME B 31.3 code, Please clarify the IMAGE CONTRAST GRAPH method .
