What is the typical E value if no RT is performed?

• A. 0.85
• B. 1.0
• C. 1.2
• D. 0.75

Answer: (B)

The value E is the examination effectiveness factor used to adjust defect acceptance based on the nondestructive testing performed. If no radiographic testing (RT) is done, you don’t get any extra credit for higher detection capability, so you use the baseline level with no RT credit. That baseline is 1.0. So, when RT is not performed, the typical E value is 1.0. Choosing values above 1.0 would reflect added credit for performing RT (increasing detection probability), while values below 1.0 would indicate less reliable inspection or reduced coverage.
