Ultrasonics Level 1

TRAINING OBJECTIVES: This course is intended to provide a basic knowledge of ultrasonic testing fundamentals sufficient to enable the technician to carry out ultrasonic testing to established procedures under the supervision of Level 2 or Level 3 personnel.

APPLICABLE STANDARDS: This program meets the requirements of CAN/CGSB-48.9712, ISO 9712 and SNT-TC-1A.

RESPONSIBILITIES OF LEVEL 1 PERSONNEL (AS PER CGSB): Level 1 personnel are defined as personnel who properly perform specific calibrations and specific evaluations for acceptance or rejection determinations, according to written instructions, and record results. Level 1 carry out industrial ultrasonics under the supervision of Level 2 or Level 3 personnel and shall receive the necessary instructions from a Level 2 or Level 3 individual.
