Magnetic Particle Levels 1 & 2

Course Overview

Training Objectives
This course provides 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 course meets the training syllabus requirements of CAN/CGSB-48.9712, ISO 9712 and SNT-TC-1A.

Definition of Level 2 Personnel (as per CGSB)
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.
