What is Magnetic Testing?
Magnetic Testing involves the magnetisation of a component, followed by the application of ferromagnetic particles. The particles align along discontinuities in the surface, or shallow sub-surface discontinuities. This method is used to test welds, castings, and forgings for surface or subsurface defects; however it can only be used on ferromagnetic metals.
What are the responsibilities of a individual who is certified to Magnetic Level 1?
An individual certified to Magnetic Level 1 has to demonstrate competence to carry out NDT according to written instructions and under the supervision of Level 2 or Level 3 personnel. Within the scope of the competence defined on the certificate, Magnetic Level 1 personnel may be authorised by the employer to perform the following in accordance with NDT instructions:
- Set up Magnetic Testing equipment;
- Perform the Magnetic Inspection tests;
- Record and classify the results of the tests according to written criteria;
- Report the results
Level 1 certified personnel shall neither be responsible for the choice of test method or technique to be used, nor for the interpretation of test results.
