NDT LEVEL-II (SNT-TC-1A)

Non-destructive Testing is part of the function of Quality Control and is complementary to other long established methods. By definition non-destructive testing is the testing of materials, for surface or internal flaws or metallurgical condition, without interfering in any way with the integrity of the material or its suitability for service. The technique can be applied on a sampling basis for individual investigation or may be used for 100% checking of material in a production quality control system. Non-destructive Testing is not just a method for rejecting substandard material; it is also an assurance that the supposedly good is an actual good. The technique uses a variety of principles; there is no single method around which a black box may be built to satisfy all requirements in all circumstances.
  The ASNT NDT Level II program provides third-party certification for non-destructive testing (NDT) personnel whose specific jobs require knowledge of the technical principles underlying the non-destructive tests they perform witness, monitor or evaluate. The program provides a system for ASNT NDT Level II certification in NDT accordance with Recommended Practice No. SNT-TC-1A.
  Certification under this program results in the issuance of an ASNT certificate and wallet card attesting to the fact that the certificate holder has met the published guidelines for the Basic and Method examinations as detailed in Recommended Practice No. SNT-TC-1A.
