Which level of NDT personnel is primarily responsible for equipment calibration?

The correct choice is Level 2 personnel, who are primarily responsible for equipment calibration within non-destructive testing (NDT) frameworks. Level 2 technicians are expected to have a comprehensive understanding of the testing equipment and its operational principles, which includes the ability to calibrate and maintain that equipment to ensure accurate and reliable test results.

Level 2 personnel are trained to set up and calibrate equipment, perform tests, and interpret results according to established procedures. Calibration is a critical aspect of ensuring that NDT instruments function correctly and provide valid data, and Level 2 professionals are adequately equipped with the knowledge and skills necessary for this task.

While Level 1 personnel focus on specific handling and implementation tasks under the supervision of higher-level technicians, and Level 3 personnel are responsible for overseeing the entire NDT program, including training and technique development, it is the Level 2 personnel that are tasked specifically with calibration activities. This distinction highlights the progressive nature of qualifications and responsibilities within NDT certifications.
