Principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT) are established. The term 'industrial' implies the exclusion of medical applications. The certification covers proficiency in one or more of the following methods: acoustic emission testing; eddy current testing; leak testing (hydraulic pressure tests excluded); magnetic particle testing; penetrant testing; radiographic testing; ultrasonic testing; visual testing (direct unaided visual tests and visual tests carried out during the application of another NDT method are excluded).
An employer's qualification system for nondestructive testing personnel inspecting the following steel products under the employer's responsibility is described: tubes and pipes (seamless and welded); flat products; long products; rails; bars; sections; rod and wire. The standard applies to NDT personnel performing predominantly automated inspection by means of eddy current, flux leakage, leak, liquid penetrant, magnetic particle, radiographic and ultrasonic testing, and visual inspection.
Guidelines 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 are given. It also establishes the minimum requirements for effective structured training of NDT personnel to ensure eligibility for qualification examinations leading to third-party certification according to recognized standards. In addition to nondestructive testing in general, its guidelines for syllabuses cover acoustic emission, eddy current, leak, magnetic particle, penetrant, radiographic, ultrasonic and visual testing.
Guidance on tests used for the characterisation of thermally sprayed coatings is given. Details regards the different types of coatings are not included. Tests listed are procedures and test criteria in general use - visual examination, surface roughness measurement and impression, crack detection, hardness, thickness, conductivity, metallographic examination, SEM, X-ray diffraction, chemical analysis, bond strength, hardness, wear, thermal shock and corrosion resistance.
A guide to basic principles of NDT and test selection is presented. The problems and limitations of NDT are described as an introduction. Types of defects, their characteristics, common locations and their relationships with welding processes have a marked influence on the selection of inspection techniques. These include: visual inspection, dye penetrant, magnetic particle, radiographic, ultrasonic, eddy current and leak testing.
Guidance is given on visual inspection prerequisites (visual acuity, equipment, experience, training, procedures, certification, safety), fundamentals, weld surface conditions and examination equipment. Illustrations are provided of weld defects commonly encountered: scattered, aligned, elongated and piping porosity; incomplete fusion; incomplete joint penetration; undercut; underfill; overlap; laminations; longitudinal, throat, crater, toe and transverse cracks; slag inclusions; convexity; spatter; and surface oxidation.
This standard describes testing procedures and test pieces required for the nondestructive testing of brazed joints. The nondestructive examination methods described are: visual examination, ultrasonic examination, radiographic examination, penetrant detection, leak testing, proof testing and thermography. For each method, details are given of personnel qualifications, equipment, acceptance guidelines and test results and information to be reported. Imperfections in brazed joints are described in Annex A.
This standard specifies the general principles for visual testing both directly and remotely when it is used to determine the compliance of a product with specified requirements (e.g. surface condition of the part, alignment of mating surfaces, shape of part).
The standard details the visual testing of fusion welds in metallic materials. It may also be applied to visual testing of the joint prior to welding. Test conditions, personnel qualification, and data recording are also specified.
An information document providing guidance on the design and evaluation of various welded joint types and geometrical configurations subject to nondestructive testing (NDT). Test methods covered are: visual, ultrasonic, radiographic, magnetic particle and penetrant testing. Illustrations of the general NDT evaluation of welded joints are given in tabular form, indicating the suitability of the test methods for different types of welded joints. A second table shows the evaluation of more specific examples. 2ff7e9595c
