ASNT NDT Level III Certification - Magnetic Flux Leakage (MFL)
Credential: ASNT NDT Level III Certification - Magnetic Flux Leakage (MFL)
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. Magnetic flux leakage (MFL) is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic principle is that a powerful magnet is used to magnetize the steel. Candidates must have a minimum of 4 years of experience in an assignment at least comparable to that of a Level II in Magnetic Flux Leakage. 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.
More information can be found on the certifying agency's website.
