What qualifies an individual as NDT trained personnel at level 1?

To qualify as NDT (Non-Destructive Testing) trained personnel at level 1, an individual must possess basic theoretical knowledge as well as some practical on-the-job training related to NDT methods. This level of certification indicates that the individual is capable of performing certain types of NDT under direct supervision and is familiar with the basic principles and practices. The focus is on ensuring that the individual can accurately perform tests and understand basic concepts, rather than requiring an extensive level of experience or advanced theoretical knowledge required at higher levels.

Basic theory provides a foundational understanding of the methodologies in NDT, while on-the-job training ensures that the individual has practical experience with specific testing techniques and equipment. Higher levels of training would require more advanced knowledge and a greater amount of practical experience, which is not the requirement for level 1 qualification. Thus, this combination of basic theory and some hands-on training distinctly defines someone as qualified at the level 1 standard in NDT.
