TRAINING OBJECTIVES: This course is intended to provide detailed instruction in the theory and practices of magnetic particle inspection, including the capabilities and  limitations of the method. Instruction will be given in generally accepted inspection techniques in accordance with codes and standards.

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

DEFINITION OF LEVEL 2 PERSONNEL: Level 2 personnel are defined as personnel qualified in magnetic particle testing who will perform and/or direct magnetic particle inspection according to established or recognized procedures and shall be responsible for the magnetic particle method or technique to be used, and for the assessment of test results.
