Final answer:
Only certified nondestructive testing personnel should interpret the results of tests, as this ensures accuracy and reliability in the vital technical and safety assessments.
Step-by-step explanation:
Only certified nondestructive testing personnel shall interpret test results. Nondestructive testing (NDT) involves evaluating the properties of a material, component, or system without causing damage. Due to the technical and safety-related nature of the interpretations, it's vital that the individuals responsible are not only experienced but are also formally certified as per industry standards. Certification provides a formal recognition of the proficiency and comprehension in understanding the NDT methods and results, ensuring that the interpretations are accurate and reliable.
