Misconceptions within magnetic testing

This document is based on a conference given by George HOPMAN, in Las Vegas, on 13 November 2007.
It is important to know a bit more about this man, well known - and renowned - in the American NDT world. You may find his résumé at the end of this paper.

A somewhat unscrupulous supplier

In many areas of the business life, including Penetrant Testing, we may rely upon our suppliers … until one of them, (a rarity for sure), make us think the other way.

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.
Nevertheless, we are convinced that our site may be a kind of surge-valve: the topic is NOT to target this company, or that auditor; but it is always to make users think, to make them ask themselves, or others, the right questions.

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.
