ASNT NDT Level II Certification - Magnetic Particle Testing (MT)
Credential: ASNT NDT Level II Certification - Magnetic Particle Testing (MT)
Credentialing Agency: American Society for Nondestructive Testing (ASNT)
Renewal Period: 5 years
The ASNT NDT Level II program provides third-party certification for nondestructive testing (NDT) personnel whose specific jobs require appropriate knowledge of the NDT method(s) for which certification is sought. Magnetic Particle Testing uses one or more magnetic fields to locate surface and near-surface discontinuities in ferromagnetic materials. The magnetic field can be applied with a permanent magnet or an electromagnet. When using an electromagnet, the field is present only when the current is being applied. When the magnetic field encounters a discontinuity transverse to the direction of the magnetic field, the flux lines produce a magnetic flux leakage field of their own. Candidates must have a minimum of 530 hours of experience in NDT with 280 hours in the specialty, a minimum of 20 hours of training in the specialty, and agree to abide by the code of ethics of ASNT Level II personnel. Candidates applying for initial certification must take both the general examination and at least one specific examination in each test method for which certification is sought.
More information can be found on the certifying agency's website.
