PURPOSE AND RATIONALE OF THE QUALIFICATION 
Purpose:
The purpose of the Advanced Diploma in Non-Destructive Testing is to develop the necessary knowledge, understanding, skills and competence of learners' to be able to further their learning towards becoming capable technologists in the Non-Destructive Testing (NDT) discipline at a supervisory level. A successful learner will demonstrate competence in using NDT methods and related fields that are included in the curriculum. Upon completion, a qualifying learner should be competent in solving complex problems related to NDT.

Modules such as Fracture Mechanics, Numerical Analysis with Mat lab applications and NDT Projects IV are some of the modules that will be presented in the qualification, and these will be invaluable as tools of investigation and analysis. This qualification thus forms the baseline in Non-Destructive Testing failure investigation and the range of methods that can be applied to avert component failure. In particular, the methods to be studied have more in-depth key concepts and mathematical analysis, which is needed in specialised investigations and/or innovative advancement in component inspection.

The envisaged occupations or areas of activity for qualifying learners will be to tackle problems that have emanated from Non-Destructive Testing reports and/or seek for innovative scientific methods to improve the inspections, thereby contributing to revision of the applicable standards. This will be within a plant environment; the output of which will improve inspection instructions and/or guidelines for the Non-Destructive Testing technicians. This will further position them to progress to Research and Development, if they so wish, and to Postgraduate Diploma in Non-Destructive Testing (NQF Level 8). They will therefore be best suited for employment in end-user companies of Non-Destructive Testing as opposed to the services companies. They will also contribute to the development and management of Non-Destructive Testing related business ventures, at community and industrial levels.

The qualification is designed and aligned with the development of skills and competence in Non-Destructive Testing. The development of critical skills in the specialised techniques in the Advanced Diploma in Non-Destructive Testing is designed to focus on a range of different technical and material science application. The learners will also gain team-leading skills and be able to develop applicable critical and innovative thinking skills.

The qualification is firmly within the Materials Testing/Evaluation classification of subject matter. It focusses on the major, often applied methods of non-invasive inspection and concomitant techniques for evaluating material integrity. This includes most importantly, understanding the cause and effect in material failure using computational simulation modelling.

Rationale:
With the lack of knowledgeable Non-Destructive Testing (NDT) technicians in South Africa, this qualification will pave the way for learners to acquaint themselves with the necessary foundation aspects in order to solve complex problems in NDT nationally and internationally.

Due to a lack of suitably qualified technologists in the discipline of Non-Destructive Testing this qualification has been identified to enable learners to register for a technologist status provided learners complete an Advanced Diploma at NQF Level 7 in Non-Destructive Testing. Non-Destructive testing is a niche area and a 'gap' in the industry has been identified, thus the Advanced Diploma in Non-Destructive Testing has been developed to widen articulation progression to Postgraduate studies.

Relevant industry stakeholders have been consulted in the curriculum development (Doc D) of the qualification. The qualification was mooted and discussed in the Non-Destructive Testing advisory board meeting, which includes members from the role players in the industry. Some of the advisory board members are also active members or hold office in the South African Institute for Non-destructive Testing (SAINT) and with the recognised SAINT Professional Body for Non-Destructive Testing (SPBNDT).

The qualification will be useful for end-user industries, since it will start to address, Remaining Useful Life (RUL) of components and by extension, plant machinery. This has huge cost implications in relation to maintenance and confidence in the continued operation of the plant. For example, graduates will thus 'plug' the missing input when engineering teams are deliberating at a technical level on plant maintenance schedules. The typical learners who will be enrolling for this qualification would have a 360-Credit Diploma.

    INTERNATIONAL COMPARABILITY 
    A comparability study was conducted with the following international institutions:
  • National Technical University of Ukraine in Ukraine that offers a Non-Destructive Testing Instrumentation and Systems qualification.
  • Lowa University in the United States of America (USA) that offers a Non-Destructive Evaluation (NDE).

    The qualification offered in Ukraine trains specialists in the specialty "automation and computer integrated technologies", specialisation "Computer-integrated technologies and systems of non-destructive control and diagnostics". The main direction of educational work is training of self-sufficient specialists in the design and operation of systems of non-destructive control of constructions materials and technical diagnostics of machinery. Graduates of the qualification will receive the necessary training to work in the field of medical engineering; Software and technical support of the educational process of the Department of Non-Destructive Testing Instruments and Systems.

    The learners will acquire knowledge and skills to work with different software products for designing better devices and non-destructive testing systems.

    Thus learners will be able to:
    Perform research activities in the following directions:
  • Methods of control of the stress state and fatigue of structural materials.
  • Acoustic and eddy-current flaw mobile detectors.
  • Ultrasonic methods and devices for the medical diagnostics needs.
  • Development of precision measuring instruments magnetic and electric fields.
  • Electrical methods for mineral exploration.
  • Research and development of thermal method of non-destructive testing.
  • Development of techniques to improve the quality of training of specialists in non-destructive testing and technical diagnostics. Rules for admission of foreigners and stateless persons to study at the National Technical University of Ukraine "Igor Sikorsky Kiev Polytechnic Institute".

    The qualification offered in the USA utilises a number of techniques to determine the health of an engineering component or structure without affecting its usefulness. Much like a doctor may use ultrasound or radiography to assess the health of the body, engineers use these and other techniques to decide if material properties are within an acceptable range, if a component was well manufactured, or if damage has occurred in service that would warrant retirement. NDE professionals are active in all phases of engineering, from design to manufacturing to in-service use, and in all industry sectors including aviation, power generation, transportation, manufacturing, and many others.
