Which type of tests may an ASNT Level III prepare personnel to administer?

An ASNT Level III certified individual possesses a high level of expertise in nondestructive testing (NDT) methods, allowing them to prepare personnel for administering various types of tests. These tests include ultrasonic, magnetic particle, and radiographic testing, among others. The role of a Level III is to ensure that the methods are carried out correctly, adhere to applicable standards, and produce reliable results.

Ultrasonic testing uses high frequency sound waves to detect imperfections within materials, while magnetic particle testing is effective for identifying surface and near-surface discontinuities. Radiographic testing involves the use of radiation to visualize internal features of a material. Each of these methods serves a unique purpose and is crucial in ensuring the integrity of materials and components without causing damage.

By contrast, the other options are limited in scope. Destructive tests, while important for certain material evaluations, fall outside the realm of NDT, which focuses on preserving the integrity of the test item. Visual inspections, while a component of many NDT processes, do not encompass the full range of techniques that an ASNT Level III would be qualified to oversee. Similarly, limiting the scope to only ultrasonic testing methods ignores the broader capabilities inherent in the Level III certification.
