Kusnadie,
I guess you mean Magnetic Particle Inspection ASNT Level 1 or 2 in MT, or PCN Level 1 or 2 in MT, and it can be done to most Specs ASME, API, ANSI just depends on which code you are working to. But ASME V appendix 6 Methods for Magnetic Particle Examination (MT) should cover you for most things. Hope that has helped you.

Phil

Electromagnetic inspection is normally divided in 2 catagories
a. Eddy current inspection - typically performed on non magnetic materials - and commonly used in the inspection of aerospace components and things like thin walled boiler tubes
b. Magnetic flux leakage testing - performed on ferromagnetic materials and most commonly used in the inspection of oilfield tubulars and tank floors
Eddy current inspectors are typically qualified at level 1 or 2 in the ASNT or PCN systems - I'm not sure about which codes and standards are applicable to this method
Magnetic flux leakage testing was recognised as a separate method in SNT-TC-1A 2006 and there is a training syllabus and example questions in htis document. At this time I'm not aware of anyone doing formal training and qualification in the Magnetic flux leakage method although I'll be happy to be corrected on this point
My area of specialisation is the inspection of oilfield tubulars using the MFL method and there are several applicable standards issued by the American Petroleum Institute (API) which address the MFL method including API 5CT, API RP5A5, APIRP-7G-2 etc

Hope this helps

Thanks Bruce I have not been involved with Eddy Current inspection so this has helped me also.

Eddy curent bsaed inspections are frequently performed on ferritic materails. I know becacuse I have developed equipment for those applications, including "blind" inspection where MPI could not be done without major dismantling.

The FGI technology that I developed well lends itself to mapping the damage at the rail-wheel interface and reveals patterns of damage/defects ot revealed in other ways. It provides other valuable means of condition assessment.

You can get PCN certification in Eddy Current weld inspection from most of the training schools in the UK.

Eddy Current Inspection of welds both Ferromagnetic and Non-Ferrromagnetic is covered by the European Standard EN1711:2000. It has particular advantages in inspecting though coated surface (both conductive and non-conductive) and in poor access areas when compared with MPI.
