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 SNT-TC-1A, BINDT/PCN, CAN/CGSB-48.9712 and ISO-9712.
RESPONSIBILITIES OF LEVEL 1 PERSONNEL: 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.
