Magnetic Particle Testing

Magnetic Particle Testing is an Conventional Testing Method which involves the component under testing being magnetized. This magnetization process is supplemented by the application of ferromagnetic particles to the already magnetized surface. The magnetic particles are attracted to areas of flux leakage (escaping magnetism) and form an indication at that point.

This NDT method is used to test welds, castings, and forgings for surface or slightly subsurface defects. However Magnetic Particle Testing can only be used to inspect materials that can be magnetized, i.e. ferromagnetic materials.

The SGS NDT Training Center provides NDT Magnetic Particle Testing Courses and Examinations suitable for any of the following certification schemes:

• PCN/EN473/ISO 9712 Levels 1, 2, and 3
• Preparation training for ASNT Level 3
• SNT-TC-1A in accordance with your company's written practice
