GB/Z 43414-2023 Non-destructive testing - NDT training syllabuses
1 Scope
This document gives requirements and recommendations for non-destructive testing (NDT) training syllabuses, with the intention of harmonizing and maintaining the general standard of training of NDT personnel for industrial needs.
It also establishes the minimum requirements for effective structured training of NDT personnel to ensure eligibility for qualiication examinations leading to third-party certiication according to recognized standards. In addition to non-destructive testing in general, its guidelines for syllabuses cover acoustic emission testing, eddy current testing, leak testing, magnetic testing, penetrant testing, radiographic testing, ultrasonic testing, visual testing, thermographictesting,and strain gauge testing.
ISO/TS 25108 gives requirements and recommendations for NDT training organizations.

ISO 9712, Non-destructive testing - Qualiication and certiication of NDT personnel
3 Terms and deinitions
For the purposes of this document, the following terms and deinitions apply.
3.1
adjustment
set of operations carried out on a measuring system so that it provides prescribed indications corresponding to given valuesof a quantity to be measured
Note: Types ofadjustment of a measuringsystem include zero adjustment, offset adjustment, and span adjustment (sometimes called gain adjustment).
4 General
4.1 NDT training
Training syllabuses by themselves cannot guarantee competence of the trainees to provide adequate technical knowledge, since it is quite common that some students achieve excellent results whereas others fail in the same class. ISO 9712 provides the minimum training requirements for candidates who possess adequate skills and prior knowledge. If it is not the case, consideration for additional training should include:
a) level 1,2 and 3——mathematics;
b) level 1,2 and 3——materialsandprocess;
c) level 3——general knowledge common course applicable to all NDT methods.
As speciied in ISO 9712, direct access to the level 2 examination requires the total training time for level 1, level 2 and direct access to level 3 requires the total training time shown for level 1, level 2 and level 3.
ISO 9712 also provides the opportunity for reductions in training duration for candidates seeking certiication in more than one method or who have a certain educational degree in an NDT relevant subject. Thus, the training organizations should use discretion when implementing the syllabuses respective of their training environment taking into consideration product/industrial sectors and development or use of common focused courses which pertain to all NDT methods in developing their training curriculum.
4.2 Levels of competence
A three-levelscheme,inaccordance with ISO 9712, isused to deine levels of competence to indicate the required depth of understanding, knowledge and application of material.
Level 1
——Acquire a generalknowledge of topic areas.
——Identify equipment and accessories.
——Identify common reference documents.
——Recognize when material is applicable orwhy it is relevant.
——Demonstrate understanding by performing instructed inspection tasks.
Level 2
——Attain a sound understanding of concepts and principles.
——Develop a sound conceptual and comprehensivetechnical knowledge.
——Develop a sound working knowledge of procedures.
——Become familiar with common reference documents.
——Become proicient in the application of knowledgeto practice.
——Apply concepts and techniques to inspection situations.
——Analyse information to make preliminary conclusions.
Level 3
——Attain an in-depth understanding of concepts and principles.
——Develop in-depth comprehensive technicalknowledge of procedures.
——Be proicient in the application of knowledge to practice.
——Be proicient with theuse of reference documents.
——Analyse information to form conclusions.
——Apply concepts and techniques to new inspectionsituations.
Note: Where topics/subjects/content are listed across multiples levels in Tables 1 through 21, this indicates a more in-depth knowledge is required at the higher level(s).
4.3 General environmental and safety considerations
4.3.1 Non-destructive testing is often applied in conditions where the safety of the operator can be in danger owing to local conditions, or where the application of the particular NDT method or technique itself can compromise the safety of theoperator and others in the vicinity.
An essential element of any training for NDT personnel shall therefore be safety. The duration of the training for this subject should be adequate and be provided in addition to the technical training associated witha particular NDT method.
4.3.2 Additional training in radiation safety shall be required prior to radiographic training.
4.3.3 General safety considerations include, but are not necessarily limited to, the following:
——environmental conditions (heat, cold, humidity);
——toxicity (NDT materials, tested products,atmosphere);
——radiation safety (NDT materials, products);
——electrical safety (NDT equipment, lethal voltages, M);
——potentialfor injury to personnel (working at height or in otherdangerous environments);
——personalprotection equipment(clothing, radiation dosimeters);
——pressure test safety.
