NDT is a quality control phase in the manufacturing, fabrication and construction of steel structures that, by means of examination or measurement to determines the condition of the structures to predetermined quality requirements.

The NDT personnel are responsible to the owner/user to assure the quality manufacturing, fabrication and construction of steel structures meet the specifications and codes requirement during one or more of the following processes;
A. welding, B. machining, C. casting, D. rolling, E. forging, and F. heat treatment.

All NDT activities shall be performed by personnel certified as qualified to perform NDT as Level 1, Level 2, or Level 3 as described in Section 6.0 below.

Job Tasks

The NDT personnel shall be competent in performing the following tasks;
a. Select NDT methods, techniques and procedure by the given type and configuration of steel structures.
b. Select equipment, accessories and consumables required by the procedure.
c. Check the equipment performance and calibration.
d. Set-up equipment for NDT works.
e. Make the proper surface preparation of the test surface for NDT works.
f. Perform the required NDT works.
g. Identify, evaluate and measure the test indications produced by NDT works.
h. Accept or reject the measured indication against the relevant acceptance criteria.
i. Write a precise NDT report for used by production and/or client's disposal.
j. Explain the detail finding to the supervisor and/or engineer in-charge, when required.

Level of Certification

1. Level I

    An NDT Level 1 individual shall have sufficient technical knowledge and skills to be qualified to properly perform specific standardizations, specific NDT, and specific evaluations for acceptance or rejection determinations according to written instructions and to record results.
    The NDT Level 1 shall receive the necessary instruction and supervision from a certified NDT Level 2 or 3 individual.
2. Level II

    An NDT Level 2 individual shall have sufficient technical knowledge and skills to be qualified to set up and standardize equipment and to interpret and evaluate results with respect to applicable codes, standards, and specifications.
    The NDT Level 2 shall be thoroughly familiar with the scope and limitations of the methods for which qualified and should exercise assigned responsibility for on-the-job training and guidance of trainees and NDT Level 1 personnel.
    The NDT Level 2 shall be able to organize and report the results of NDT tests.
3. Level III

    An NDT Level 3 individual shall have sufficient technical knowledge and skills to be capable of developing, qualifying, and approving procedures; establishing and approving techniques; interpreting codes, standards, specifications, and procedures; and designating the particular NDT methods, techniques, and procedures to be used.
    The NDT Level 3 shall be responsible for the NDT operations for which qualified and assigned and should be capable of interpreting and evaluating results in terms of existing codes, standards, and specifications.
    The NDT Level 3 shall have general familiarity with other appropriate NDT methods, as demonstrated by an ASNT Level III Basic examination or other means.
    The NDT Level III, in the methods in which certified, shall have sufficient technical knowledge and skills to be capable of training and examining NDT Level 1, 2, and 3 personnel for certification in those methods.


Applicants for certification in NDT shall have sufficient education and experience to ensure qualification in those NDT methods in which they are being considered for certification.

Documentation of prior certification may be used as evidence of qualification for comparable levels of certification.

The applicant documents required include a listing of all educations, relevant work and employment. The documents shall include:

    A. an education background with relevant supporting documents,
    B. a listing of all relevant employers and their contact information when available,
    C. the nature of the work performed, the dates of employment, and
    F. a letter of verification from the employer or client.
The educations, relevant work and employment documentation is subject to verification by Certification Department and false information is caused to reject the application and can disqualify the applicant from testing to become NDT Level 1, Level 2 or Level 3 personnel.

Table 1 lists the required hours experience to be considered for the pre-requisite of NDT Level 1 and Level 2 application.

Table 2 lists the required hours experience for limited certifications. Limited certification applies to individuals who do not meet the full experience of Table 1.

Table 3 lists the required education and experience to be considered for the pre-requisite of NDT Level 3 application.

If the applicant is being qualified directly to Level 2, with no time at Level 1, the experience shall consist of the sum of the times required for Level 1 and Level 2.

If the applicant is being qualified directly from Level 1 to Level 3, with no time at Level 2, the experience shall consist of the sum of the times required for Level 2 and Level 3.

Quality Assessment

The applicant shall fulfil the minimum requirements of education, training, experience, examinations and vision prior to certification.

The applicant shall provide documentary evidence, acceptable to RSA, the following:
e. education,
f. experience,
g. satisfactorily completed training, and
h. recent vision test.

Certification Department shall verify the examination grades given by the Examination Department.

For RT, the applicant shall hold a valid radiation safety certification from the relevant local authority.

Certification Validity

Certification becomes effective from the date of completion of the initial examination and shall be valid for five (5) years unless revoked for reasons defined in Sections 18.0 and 20.0.

Condition Of Certification

The period of validity shall commence (date of issue of the certification) when all of the requirements for certification (education, training, experience, satisfactory vision test, success in examination) are fulfilled. Certification becomes invalid:

  1. at the discretion of RSA, e.g. after reviewing evidence of behaviour incompatible with the certification procedures or failure to abide by a code of ethics,
  2. if the NDT personnel becomes physically incapable of performing his duties based upon failure of the visual acuity examination taken annually under the responsibility of his employer,
  3. if the NDT personnel has not been actively engaged in the performance of the certified NDT method for a period of six (6) months or more during the certification period,
  4. if the NDT personnel fails recertification, until such time he/she meets the requirements for recertification or initial certification, and
  5. if examination or certification fees are not paid when due.
