ASNT NDT Level III Certification - Liquid Penetrant Testing (PT)
Credential: ASNT NDT Level III Certification - Liquid Penetrant Testing (PT)
Credentialing Agency: American Society for Nondestructive Testing (ASNT)
Renewal Period: 5 years
The ASNT NDT Level III program provides third-party certification for nondestructive testing (NDT) personnel whose specific jobs require knowledge of the technical principles underlying the nondestructive tests they perform, witness, monitor or evaluate. Liquid Penetrant Testing (PT) is used to reveal surface discontinuities and makes it easier to detect flaws than an unaided visual inspection. Liquid penetrant testing is one of the most widely used NDT methods. Its popularity can be attributed to two main factors: its relative ease of use and its flexibility. It can be used to inspect almost any material provided that its surface is not extremely rough or porous. Materials that are commonly inspected using this method include; metals, glass, many ceramic materials, rubber and plastics. Candidates must have a minimum of 4 years of experience in an assignment at least comparable to that of a Level II in Liquid Penetrant Testing. ASNT NDT Level III certification candidates are required to pass both the NDT Basic and a method examination in order to receive the ASNT NDT Level III certificate.
