COURSE OVERVIEW

 

This hands-on, highly-interactive course includes various practical sessions and exercises.  Theory learnt will be applied using our state-of-the-art simulators. 

 

This course is designed to provide participants the theory lectures and practical training with a preliminary understanding of Visual Testing (VT), Liquid Penetrant Testing (PT) and Magnetic Particle Testing (MT) as per the ANSI/ASNT CP-105-2016 Standard for qualification of non-destructive testing personnel and as per the ASNT Recommended Practice No. SNT-TC-1A 2016 for Personnel Qualification and Certification in Non-destructive Testing. 

 

This course covers the visual testing applications; the liquid penetrant testing equipment including the principles of magnets and magnetic fields; the liquid penetrant processing and various penetrant testing methods; the characteristics of magnetic fields and the effect of discontinuities of materials; magnetization by means of electric current; the proper method of magnetization and the principles of demagnetization; the magnetic particle testing equipment; the types of discontinuities detected by magnetic particle testing; and and magnetic particle test indications and interpretations. 

 

Sample Questions for general examinations will be presented in the question booklet A that was obtained from ASNT headquarters.  Participants will further demonstrate familiarity with and ability to operate the necessary equipment for VT, PT and MT, record and analyze the resultant information to the degree required as well as test flawed specimen and component and analyze the results of NDT as part of the practical training. 

 

At the completion of the course, participants will be appearing for a Level I exam.  Each candidate will be a ‘Certified ASNT NDT Level I in Visual Testing, Liquid Penetrant Testing and Magnetic Particle Testing’ upon successfully passing the examination with a minimum passing composite grade of at least 80 percent (%). 

 

Examinations Category & Criteria 

Vision Examinations 

·      Near-Vision Acuity 

o   This examination will ensure natural or corrected near-distance acuity in at least one eye such that the applicant is capable of reading a minimum of Jaeger Number 2 or equivalent type and size letter at the distance designated on the chart but not less than12 inches (30.5 cm) or a standard Jaeger test chart.  The ability to perceive an Ortho-Rater minimum of 8 or similar test pattern is also acceptable.  This examination shall be administered annually. 

·      Color Contrast Differentiation 

o   This examination will demonstrate the capability of distinguishing and differentiating contrast among colors or shades of gray used in the method as determined by the employer.  This shall be conducted upon initial certification and at five-year intervals thereafter 

 

General (Written) 

·      This examination will address the basic principles of the applicable method 

·      The NDT Level III will provide appropriate questions covering the applicable method to the degree required by the employer’s written practice 

·      The minimum number of examination questions that will be given is 40 

Specific (Written) 

·      This examination will address the equipment, operating procedures and NDT techniques that the individual may encounter during specific assignments to the degree required by the employer’s written practice 

·      The specific examination will also cover the specifications or codes and acceptance criteria used in the employer’s NDT procedures 

·      The minimum number of examination questions that will be given is 20 

·         The candidate shall demonstrate familiarity with and ability to operate the necessary NDT equipment, record and analyse the resultant information to the degree required 

·         At least one flawed specimen or component shall be tested and the results of the NDT analysed by the candidate 

·         The description of the specimen, the NDT procedure including check points and the results of the examination shall be documented 

·         Proficiency shall be demonstrated in performing the applicable NDT technique on one or more specimens or machine problems approved by the NDT Level III and in evaluating the results to the degree of responsibility as described in the employer’s written practice. At least ten (10) different checkpoints requiring an understanding of test variables and the employer’s procedural requirements will be included. The candidate shall detect all discontinuities and conditions specified by the NDT Level III 

Note: While it is normal to score the practical on a percentile basis, practical examinations will contain check points that failure to successfully complete will result in failure of the examination 

Additional Criteria 

All written examinations will be closed-book except that necessary data such as graphs, tables, specifications, procedures, codes, etc., may be provided during the examination. All questions are approved by the responsible NDT Level III.
