American Society for Nondestructive Testing (ASNT) Radiographic Testing Practice Test

The recommendation for the number of test specimens for Level I and Level II practical examinations is that one or more test specimens are ideal. This approach allows for flexibility in the examination process while still ensuring that candidates have the opportunity to demonstrate their capabilities in performing tasks relevant to radiographic testing.

Having at least one test specimen allows the examiner to evaluate the candidate’s understanding of the procedures and techniques involved in radiography. The phrase "one or more" captures the necessity of having sufficient material to assess a candidate's practical skills without imposing a strict requirement for a minimum number, which can be beneficial in varying testing environments and contexts.

While having multiple specimens can enhance the evaluation by allowing for more diverse testing scenarios, the core purpose remains rooted in assessing the fundamental skills with at least one specimen. This is aligned with the need to maintain a balance between comprehensive skill evaluation and practical logistical considerations.
