This Recommended Practice has been prepared to establish guidelines for the qualification and certification of NDT personnel whose specific jobs require appropriate knowledge of the technical principles underlying the nondestructive tests they perform, witness, monitor, or evaluate. 1.2 This document provides guidelines for the establishment of a qualification and certification program. 1.3 These guidelines have been developed by The American Society for Nondestructive Testing, Inc., to aid employers in recognizing the essential factors to be considered in qualifying personnel engaged in any of the NDT methods listed in Section 3. 1.4 It is recognized that these guidelines may not be appropriate for certain employer's circumstances and/or applications. In developing a written practice as required in Section 5, the employer should review the detailed recommendations presented herein and modify them, as necessary, to meet particular needs. Such modification may alter but shall not eliminate basic provisions of the program such as training, experience, testing, and recertification. Supporting technical rationale for modification of detailed recommendations should be provided in an Annex to the written practice. 2.0 Definitions 2.1 Terms included in this document are defined as follows: 2.1.1 Certification: written testimony of qualification. 2.1.2 Certifying Authority: the person or persons properly designateci in the written practice to sign certifications on behalf of the employer. 2.1.3 Certifying Agency: the employer of the personnel being certified. 2.1.4 Closed Book Examination: an examination administered without access to reference materia! except for materials supplied with or in the examination (See 8.1.3.). 2.1.5 Comparable: being at an equivalent or similar level of NDT responsibility and difficulty as determined by the employer's NDT Level III. 2.1.6 Documented: the condition of being in written form. 2.1. 7 Employer: the corporate, private, or public entity, which employs personnel for wages, salary, fees, or other considerations. 2.1.8 Experience: work activities accomplished in a specific NDT method under the direction of qualified supervision including the performance of the NDT method and relateci activities but not including time spent in organized training programs. 2.1.9 Grading Unit: A Qualification Specimen can be divided into sections called grading units, which do not have to be equal length or be equally spaced. Grading units are unflawed or flawed and the percentage of flawed/unflawed grading units required should be approved by the NDT Level III. 2.1.10 Limited Certification: nondestructive test methods may be further subdivided into limited disciplines or techniques to meet specific employer's needs; these are NDT Level II certifications, but to a limited scope. 2.1.11 Nondestructive Testing: a process that involves the inspection, testing, or evaluation of materials, components, and assemblies for materials' discontinuities, properties, and machine problems without further impairing or destroying the part's serviceability. Throughout this document the term NDT applies equally to the NDT inspection methods used for material inspection, flaw detection, or predictive maintenance (PdM) applications. 2.1.12 Outside Agency: a company or individual who provides NDT Level III services and whose qualifications to provide these services have been reviewed by the employer engaging the company or individual. 2.1.13 Qualification: demonstrated skill, demonstrated knowledge, documented training, and documented experience required for personnel to properly perform the duties of a specific job. 2.1.14 Recommended Practice: a set of guidelines to assist the employer in developing uniform procedures for the qualification and certification of NDT personnel to satisfy the employer's specific requirements. 2.1.15 Technique: a category within an NDT method; for example, ultrasonic thickness testing. 2.1.16 Training: an organized program developed to impart the knowledge and skills necessary for qualification. 2.1.17 Written Practice: a written procedure developed by the employer that details the requirements for qualification and certification of their employees. 3.0 Nondestructive Testing Methods 3.1 Qualification and certification of NDT personnel in accordance with this Recommended Practice is applicable to each of the following methods: Acoustic Emission Testing Electromagnetic Testing Ground Penetrating Radar Guided Wave Testing Laser Testing Methods Leak Testing Liquid Penetrant Testing Magnetic Flux Leakage Magnetic Particle Testing Microwave Technology Neutron Radiography Testing Radiographic Testing Thermal/Infrared Testing Ultrasonic Testing Vibration Analysis Visual Testing 4.0 Levels of Qualification 4.1 There are three basic levels of qualification. The employer may subdivide these levels for situations where additional levels are deemed necessary for specific skills and responsibilities. 4.2 While in the process of being initially trained, qualified, and certified, an individua! should be considered a trainee. A trainee should work with a certified individual. The trainee should not independently conduct, interpret, evaluate, or report the results of any NDT test. 4.3 The recommended technical knowledge and skill sets for the three basic levels of qualification are as follows: 4.3.1 NDT Level I. An NDT Level I individua! should have sufficient technical knowledge and skills to be qualified to properly perform specific calibrations, specific NDT, and specific evaluations for acceptance or rejection determinations according to written instructions and to record results. The NDT Level I should receive the necessary instruction and supervision from a certified NDT Level II or III individual. 4.3.2 NDT Level II. An NDT Level II individuai should have sufficient technical knowledge and skills to be qualified to set up and calibrate equipment and to interpret and evaluate results with respect to applicable codes, standards, and specifications. The NDT Level II should 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 I personnel. The NDT Level II should be able to organize and report the results of NDT tests. 4.3.3 NDT Level III. An NDT Level III individuai should 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 2 NDT Level III should 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 III should have sufficient practical background in applicable materials, fabrication, and product technology to establish techniques and to assist in establishing acceptance criteria when none are otherwise available. The NDT Level III should 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, should have sufficient technical knowledge and skills to be capable of training and examining NDT Level I, II, and III personnel for certification in those methods. 5.0 Written Practice 5.1 The employer shall establish a written practice for the control and administration of NDT personnel training, examination, and certification. 5.2 The employer's written practice should describe the responsibility of each level of certification for determining the acceptability of materials or components in accordance with the applicable codes, standards, specifications, and procedures. 5.3 The employer's written practice should describe the training, experience, and examination requirements for each level of certification by method and technique, as applicable. 5.4 The employer's written practice should identify the test techniques within each test method applicable to its scope of operations. 5.5 The employer's written practice shall be reviewed and approved by the employer's NDT Level III. 5.6 The employer's written practice shall be maintained on file. 6.0 Education, Training, and Experience Requirements for Initial Qualification 6.1 Candidates for certification in NDT should have sufficient education, training, and experience to ensure qualification in those NDT methods in which they are being considered for certification. Documentation of prior certification may be used by an employer as evidence of qualification for comparable levels of certification. 6.2 Documented training and/or experience gained in positions and activities comparable to those of Levels I, II, and/or III prior to establishment of the employer's written practice may be considered in satisfying the criteria of Section 6.3. 6.3 To be considered for certification, a candidate should satisfy one of the following criteria for the applicable NDT level: 6.3.1 NDT Levels I and II Table 6.3.1 A lists the recommended training and experience hours to be considered by the employer in establishing written practices for initial qualification of NDT Level I and Level II individuals. Table 6.3.1 B lists initial training and experience hours, which may be considered by the employer for specific limited applications as defined in the employer's written practice. Limited certifications should apply to individuals who do not meet the full training and experience of Table 6.3.1 A. Limited certifications issued in any method should be approved by the NDT Level III and documented in the certification records. 6.3.2 NDT Level III 6.3.2.1 Have a baccalaureate degree (or higher) in engineering or science, plus one additional year of experience beyond the Level II requirements in NDT in an assignment comparable to that of an NDT Level II in the applicable NDT method(s), or: 6.3.2.2 Have completed with passing grades at least two years of engineering or science study at a university, college, or technical school, plus two additional years of experience beyond the NDT Level II requirements in NDT in an assignment at least comparable to that of NDT Level II in the applicable NDT method(s), or: 6.3.2.3 Have four years of experience beyond the NDT Level II requirements in NDT in an assignment at least comparable to that of an NDT Level II in the applicable NDT method(s). The above NDT Leve! III requirements may be partially replaced by experience as a certified NDT Level II or by assignments at least comparable to NDT Level II as defined in the employer's written practice. 3 Table 6.3.1 A: Recommended Initial Training and Experience Levels Examination Method Acoustic Emission Electromagnetic Ground Penetrating Radar Guided Wave Laser Methods NOT Level I II I II I II I II I II I Penetrant Testing Magnetic Flux Leakage Magnetic Particle Microwave Technology Neutron Radiography Radiographic Testing I II I II I I II I II I II I II Bubble Testing Pressure Change Halogen Diode Mass Spectrometer I I II I II I II I II I II II II II I II I II Training Hours Radiographic Computed Radiography Computed Tomography Digital Radiography Building Diagnostics Electrical and Mechanical Materials Testing Time of Flight Diffraction Phased Array Experience Minimum Hours Total Hours in Method or Technique in NOT 34 210 630 210 630 210 630 210 630 60 420 240 240 70 140 210 630 3 35 105 280 105 280 280 420 70 140 70 210 70 210 210 630 420 1680 210 630 210 630 210 630 210 630 210 1260 400 1200 400 1200 400 1200 400 1200 120 800 460 460 130 260 400 1200 15 80 200 530 200 530 530 800 130 270 130 400 130 400 400 1200 800 2400 400 1200 400 1200 400 1200 400 1200 400 34 1260 1800 40 160 n/a 40 40 40 40 40 40 40 40 8 20 40 40 8 24 40 40 2 4 24 16 12 8 40 24 4 8 II II 4 H...
