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. Leak Testing (LT) is used to detect through leaks using one of the four major LT techniques: Bubble, Pressure Change, Halogen Diode and Mass Spectrometer Testing. Candidates must have a minimum of 4 years of experience in an assignment at least comparable to that of a Level II in Leak 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.

More information can be found on the certifying agency's website.

RECERTIFICATION

ASNT NDT Level III Certification - Leak Testing (LT)

Renewal Period: 5 years

The ASNT NDT Level III Certification - Leak Testing (LT) credential has the following recertification information:

  • The ASNT NDT Level III program permits ASNT Level III certificate holders to renew by "Points" at 5-year intervals. The "points" system requires that certificate holders earn 25 points during their current 5-year certification period for NDT-related activities. See the point categories and structure.
  • Personnel that cannot document 25 points during their current certification period may renew by retaking the initial method examination for each method in which certified but must do so before their current certificates expire. 

    Personnel recertifying by examination need not retake the Basic examination as long as the applicant holds one currently valid ASNT NDT Level III certificate at the time of examination and passes that examination.

In Demand

This certification is considered in demand. The U.S. Department of Labor sponsored CareerOneStop's analysis indicates the certification is frequently mentioned in online job postings.
