Prior training requirement is tabulated in number of training hours for Level 1, 2 and 3 in ISO As per ISO , the candidate must complete a course of theoretical and practical training recognized by the certification body. Training requirements may also vary depending on the number of sectors opted by the candidate. Apart from instructor led training, SNT-TC-1A also talks about virtual instructor led training, self-study, computer based training or web based training.
But inclusion of such methods is left to the discretion of the employer or the companys written practice. ISO is silent on this aspect. Conditions for reduction in training hours exist in both the documents.
The syllabi are much focused and in details, and form a solid foundation of the success of the program. A major difference in the two standards is the sector wise approach in ISO ISO defines product sectors and industrial sectors.
This is the unique feature of the standard, which aims at making specialists in particular sectors. The product sectors defined are: castings, forgings, welds, tubes and pipes, wrought products and composite materials. A number of product sectors can be combined to form an industrial sectors.
Some industrial sectors defined are manufacturing, pre and in-service testing, railway maintenance and aerospace. The certifying body is given the freedom of creating additional sectors, with welldefined scope.
Certification in any method, at any of the three levels, can be for specific sectors. The examinations, of course will be sector specific.
The experience requirement is given in ISO method-wise, but it should be noted that this is actually duration of experience required in the sector. Level III experience requirement is tabulated, but is applicable after specific educational qualification.
The pattern of examination for Level I and II is the same in both standards general, specific and practical. Specific and practical examinations in ISO are required to be sector specific. The standard is clear about identification, master report, number of areas or volumes to be tested, types of discontinuities within the specimen and the timings allowed for the examination. Number of specimens for practical examination are detailed sector-wise in a table.
The specimens used for the examination must have master reports, against which the candidates performance is graded.
ISO also requires the Level 2 candidate to be able to draft a written instruction suitable for level 1. The number of questions for specific examination depend upon the number of sectors opted by the candidate. All this ensures a certain degree of firmness in the practical examination.
Advanced NDT Training Courses
As per SNT-TC-1A, the practical examinations are evaluated on the basis of 10 checkpoints as per the employers procedural requirements. It is expected that the employer and his level III take care of all the smaller points. But prior to this, he should have passed the practical examination for level 2 in the relevant sector and method.
A candidate who is already level 2 in the same method and sector need not repeat this practical exam.
This is a good point to ensure that the candidate has done or is capable of doing hands-on work, and is better than a written testimony of the experience. The specific examination may be waived off by the employer for such candidates if the required experience is evidenced.
Personnel Qualification and Certification Activities
There is no practical examination for level III. In ISO , the main method examination stresses on application of the method in the concerned sector, and hence no separate specific examination is required.
In ISO , a person already certified to Level 1 or 2 and wanting to add another sector is required to take only the specific and practical examination in that sector. Similarly, a certified Level 3 wanting to add a sector need not take the basic examination and the level 3 knowledge related part of the method examination. But in ISO , for passing Level 1 and Level 2 examinations, a minimum grade of 70 per cent is required in general, specific, for each specimen tested in practical examination, and in written NDT instruction.
For passing Level 3, a minimum grade of 70 per cent is required in each part of the basic examination A- M aterial science and process technology, B- Certification bodys qualification and certification scheme based on ISO , C- General knowledge of at least four chosen NDT methods , and a minimum grade of 70 per cent is required in each part of the method examination D Level 3 knowledge, E Application of the method in the sector, including codes, standards etc.
But ISO seems to apply the stringency in asking 70 per cent in every part of the examination. The grading of the practical examination in ISO is to be done using weighting factors. SNTTC-1A does not specify any such factors, but talks about a minimum ten checkpoints to be included in the examination. A candidate failing the examination as per ISO has to may retake the examination twice more. The re-examination can be only in the failed part.Methods of NDT. The logic applied by ISO is that visual testing forms the base of interpreting indications of all other methods as well.
