Are black magnetic particles coloured or not?
A rather peculiar question sent to people involved in Magnetic Particle Testing!

Again and again : Are penetrant testing and magnetic particle testing definitely obsolete NDT methods ?
Though we have already written, and will write in the future, about this topic, we think it necessary to focus again on this media hype (it cannot be something less than media hype!): “Death of penetrant testing and magnetic particle testing: in their death throes”
A recently released article, in a French technical journal, may make NDT users believe that the future will be bright without PT and MT, called by some people: "historical methods."

Catering trucks and MT
Some years ago (the truth is: some decades ago!), one of us was contacted by a French airline, which owned its own Ground Support Equipment (GSE). Among this GSE, there were many catering trucks. Catering trucks are similar to very large hydraulic scissor lifts, used to supply an aircraft with meals, drinks, etc. Within some weeks, on one of the Paris airports, several catering trucks broke when in-service, fortunately without any human damage, but with a lot of meals, drinks, etc. falling down and unserviceable – at least, we hope so!!!

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.
