Which activity is not within the scope of a Level II individual according to SNT-TC-1A?

A Level II individual, as defined by SNT-TC-1A, possesses the qualifications to conduct tests, evaluate results, and perform inspections under the supervision of a Level III individual. The intention behind this structure is to allow those at higher levels to establish the techniques and methods that guide testing and evaluation.

Establishing techniques is typically reserved for individuals at the Level III designation. This is because developing and validating testing techniques requires a deeper understanding of the principles and intricacies of the testing methods, often involving the design of test protocols and parameters tailored to specific applications. Level II technicians are generally expected to apply existing procedures and techniques rather than create new ones. This delineation of responsibilities ensures that individuals with the appropriate level of expertise oversee the most critical and complex aspects of non-destructive testing.

In summary, while a Level II individual plays a vital role in performing tests and evaluations, the responsibility for establishing testing techniques lies with Level III personnel, making the correct answer related to this demarcation of duties.
