    NDT World,

    Does anyone know if a facility needs any type of certification to perform destructive testing? I am writing out a program, specifically to MIL-STD-248, to perform bend testing on welded performance qualifications, however i can not find in 248 or AWS B4.0 which clarifies whether or not the destructive testing activity needs a certification to do so, any one have info on this matter? I do hold an ASNT NDT Level III in Visual and Optical Testing but i am unsure if my cert would transcend into DT.

    Thanks in advance!

    In my long career I was involved with all aspects of testing, inspection and quality control including destructive Testing. We did not have any formal certification but we had to ensure that each test was as per a national / international standard specified in the individual specifications – for example tensile testing as per ASTM – E8. The tensile testing machine has to be calibrated again as per the relevant ASTM specification…..that means each test has to be carried out as per user specified specification and the equipment has to be certified (internally or by a third party).

    However, if you are planning to use your testing laboratory for carrying out lot of third party testing, you may need a formal certification from the national accreditation bureau. In India, we have NABL (National Accreditation Bureau for Laboratories) – who check all aspects of the lab and certify it.

    The NDT Level III certification has no value or relevance as far as mechanical / destructive testing is concerned…

    Best regards
