Q. I know that you can now achieve Level III status in a specific method by going the ASNT PdM Level III route. Is that certification interchangeable with the ASNT NDT Level III as long as the certified individual has the ASNT PdM Level III for the specific method in which he is working? J.P.
A. The two certifications are not interchangeable because of differences in the Basic exam used for each, although a code may accept either. Requirements of the Basic exam used for ASNT NDT Level III and those of the Basic exam used for PdM (Predictive Maintenance) Level III are as follows.
The Basic exam for NDT Level III certification is a four-hour exam with 135 questions covering certification programs, materials, fabrication and production technology and knowledge of other NDT test methods.
The Basic exam for PdM Level III certification is a two-hour test composed of 90 questions covering certification programs (same as the NDT Level III Basic), machinery technology and knowledge of common PdM methods.
Currently, PdM certification is only available for infrared and thermal testing (IR) and vibration analysis (VA). If personnel pass the IR or VA Method exam and the PdM Basic, they obtain a PdM certification. If they pass either Method examination and the NDT Basic exam for the method as well, they get an NDT certification. (The Method exam is the same for both; only the Basic varies.) For all other NDT test methods, only NDT certification is available.
If you have personnel with IR or VA PdM certification that need an NDT certification, all that is required is that they take the NDT Basic exam, since they have already passed the Method exams for those test methods. The reverse also applies to people with NDT certification who want PdM certification.
Q. My acceptance criteria allows an indication up to .060 in. Does this mean that an indication measuring .060 in. is acceptable or rejectable?
A. Consulting with your NDT Level III or supervisor is necessary. This will be the person to best answer this question for you, as it applies to your situation.
