Guide for good practices in MT, a help to choose the most suitable technique

Magnetic Testing (MT) is a non-destructive testing (NDT) method used to detect open to surface or subsurface (generally down to some mm deep) discontinuities, only on ferromagnetic materials. This method requires following the rules to get the best results.
You will find in this paper some useful advice. In no way, this paper can be considered as a standard or as a specification.

We, Pierre CHEMIN and Patrick DUBOSC, welcome any comment, any idea. If you have some examples you would like to see discussed here, please give us all the useful indications. If you require confidentially, we would modify locations, names and some parameters to prevent any traceability.

We may also give advice, once again on a confidential basis if needed: please, feel free to ask questions, to document our data basis: about Material Safety Data Sheets (MSDS), about environment, a chemical name you don't understand,a Penetrant process you have heard about, etc.
We have plenty of examples, some being out of all the specifications/standards, which led to the discontinuities detection, when the "current, normal, processes" prevented discontinuity finding.
