in nondestructive testing. This recommended practice identifies the specific attributes that should be considered when qualifying nondestructive test personnel. It requires the employer to develop and implement the qualifi- cation and certification of nondestructive test personnel. 2. CP-189, Qualification and Certification of Nondestructive Testing Personnel resembles SNT-TC-1A but also establishes specific attributes for the qualification and certifica- tion of nondestructive test personnel. CP-189 is a consensus standard as defined by the American National Standards Institute (ANSI). It is recognized as the American standard for nondestructive testing. It is not considered a recommended practice; it is a national standard. 3. ANSI/ASNT Standard CP-105, Topical Outlines for Qualification of Nondestructive Testing Personnel defines the subject matter for training in major nondestructive test methods. 4. ASNT Central Certification Program is the third-party certification program administered by ASNT. The program is defined in the ASNT document ACCP-CP-1 . It must be understood that documents for employer- based certification programs provide recommen- dations (or requirements) and assume that the employer who contracts can and will specify training appropriate for the application. A written practice (written procedure) details the specific process and limitation. Certification that holds the employer responsible for qualification differs from certification protocols that rely on central certify- ing agencies. Sample Recommendations from SNT-TC-1A To give an overview of the contents of these documents, the following items are specified in the 2016 edition of SNT-TC-1A . (For this discussion, the quantities cited are those that pertain to radiography.) Scope. This recommended practice provides guidelines for the qualification and certification of nondestructive testing personnel whose specific jobs require appropriate knowledge of the technical principles underlying the nondestructive tests they perform, witness, monitor, or evaluate.

Written Practice. The employer shall establish a written practice for the control and administration of nondestructive testing personnel training, examination, and certification. 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 applicable codes, standards, specifications, and procedures. Education, Training, Experience. Education, training, and experience requirements for initial qualification are defined in each ASNT certifi- cation program. Candidates for certification in nondestructive testing should have sufficient education, training, and experience to ensure qualification in those nondestructive testing methods for which they are being considered for certification. Training Programs. Personnel being considered for initial certification should complete sufficient organized training to become thoroughly familiar with the principles and practices of the specified nondestructive test method related to the level of certification desired and applicable to the processes to be used and the products to be tested. CP-105 provides topical outlines and references for training. Examinations. For Level I and II personnel, a composite grade should be determined by a simple averaging of the results of the general, specific, and practical examinations. Examinations adminis- tered for qualification should result in a passing composite grade of at least 80%, with no individual examination having a passing grade less than 70%. Vision Examination. The examination for near vision acuity should ensure natural or corrected near distance acuity in at least one eye such that the applicant can read a minimum of jaeger size 2 or equivalent type and size letter at a distance of not less than 305 mm (12 in.) on a standard jaeger test chart. This test should be administered annually. An additional examination for color discrimination at five-year intervals should demonstrate the ability to distinguish colors or shades of gray used in the method as determined by the employer. Written Examination for NDT Levels I and II. A minimum number of questions to be adminis- tered in the written examination for radiographic personnel is listed in SNT-TC-1A.
