How To Certify Your NDT Personnel
The following is a basic step-by-step guide on How To Certify Your NDT Personnel. Quality Testing Services, Inc. provides NDT Training, Consulting and Level III services to help companies like yours, certify their NDT personnel.
Establish a “Written Practice” or procedure for the qualification and certification of NDT Personnel.
The procedure should be written to comply with the American Society for Nondestructive Testing (ASNT) Document SNT-TC-1A, or National Aerospace Standard NAS – 410, or American Association of Railroads C-III, M-1002 MRSP Appendix T or one of many other documents. Your company must determine which standard is most appropriate. This procedure may be authored by your company or by a qualified Outside Agency.
Employ a NDT Level III or Use the Services of a Qualified Outside Agency
The standards described above requires NDT Level I, II & III personnel be certified by the employer. For economic reasons, an employer may opt to use a Qualified Outside Agency Level III rather than employ a full time Level III. The standards described above require a Level III to be responsible for the administration of the NDT program, training and examinations of personnel and establishing and approving techniques and procedures. This person is referred to as the Responsible Level III. Some of these duties may be delegated by the Responsible Level III.
Qualify Level I and II Personnel
Candidates must have adequate education, training, and experience in order to qualify for Level I, II or III certification. These minimum requirements are detailed in the company’s “Written Practice or Procedure for Qualification and Certification of NDT Personnel” (See Step 1). For example, an Ultrasonic Testing Level II candidate must have:
- Examinations – General, Specific and Practical Exams are required.
- Training – 80 hours of documented training in Ultrasonic Testing by a qualified instructor.
- Experience – 1600 Hours of experience under the supervision of a certified Level II or III.
A company Level III, a qualified instructor, or a qualified Outside Agency, must perform training.
Administer Certification Examinations
Level I or II candidates must pass a General, Specific, and Practical examination for each NDT method for which certification is sought. Examinations must be administered by a company Level III or an Outside Agency Level III. The candidate must also pass a vision (eye) examination. The General Examination covers NDT method theory, principles and applications. The Specific Examination tests the candidate’s knowledge of company procedures, techniques and specifications commonly used. The Practical Examination demonstrates the candidate’s ability to perform the NDT method and evaluate the results.
Employer Certification of Level I or II Personnel
The employer may certify the candidate to the appropriate level upon successful completion of the examinations. The employer must keep records of qualifications, examinations and certifications on file. An Outside Agency can only provide Level III services – certification is the responsibility of the employer. Certifications are normally valid for a period of three or years for Level I and II’s and five years for a level III.
