Some readers are facing a problem to use the links between the newsletter and our Website, thanks to the parameters of the antivirus and/or antispam set in the server through which they receive this document. A warning message may be displayed.

If you do not trust in the DPCNewsletter or if you have any doubt, you may go directly to ou Website, by following this link.

An address we strongly advise you to put in your "Favorites", to make it easy to access to the reading of this DPCNewsletter and to all the papers already released, as well as the new ones released this month.

Our monthly DPCNewsletter draws your attention on the papers published on this Website at the same time, or reminds you of some papers already published (all of them are still available and some of them have been updated!) on the same topics as those dealt with in the new papers.

Enjoy reading this letter.

Underneath, find the list of the new papers that you can read this month on our Website:

That’s good old times!

This month, we describe a thing that fitted-so-many-applications, in a time when "applications" was not written "apps" … It is likely that people under 50, or even 60, have never heard about this extraordinary item. A comparison with our today’s requirements, therefore, is valuable.

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.
