June 2011

Our Website is 3 years old since April 2011! Isn’t it funny how time slips away?

Time had come for us to look not backward, but forward, to be better.

Should we only carry out maintenance and updating of your favorite Website when dealing with Penetrant Testing and Magnetic Testing?

This was our first approach. The easiest one.

However, we thought about designing and building a brand new portal:
• More modern and professional-like.
• Easier to read and more practical.
• Ergonomic.
• Attractive.
• Friendly.
• Open-ended.

Indeed, after ca two months of work, our new portal is born.

Top right of each paper, you will find:

• The ''Print'' tab. After your clicking on the tab, the paper is displayed in a pop-up fullscreen window. The paper may then be printed: on paper, in PDF format, etc.

• The ''E-mail'' tab, right of the ''Print'' tab, which allows you to e-mail anyone the URL address of a paper that you consider as interesting.

You may still use the same link:

http://www.ressuage-magnetoscopie-penetranttesting-magnetictesting-dpc.info
that is already in your “Favorites” list!

Our monthly DPCNewsletter

will now draw your attention on the papers published on this Website at the same time, or remind you of some papers already published (all of them are still available!) on the same topics as those dealt with in the new papers. You will find using the new portal format easier than previously. Feel free to report any bug or trouble, as we are as anyone, never “failsafe”!

We will continue to welcome our readers’ comments, suggestions, criticisms … though, most often, we receive congratulations!

The authors: Pierre CHEMIN and Patrick DUBOSC are happy to be again of some help to you!

Here are the papers that you can read this month on our Website:

In the ‘‘Edito’’ section

Non-relevant versus non-significant

A vocabulary problem, in English only.
This paper, written by two French people, deals with something we feel as a problem of vocabulary.
Depending on the documents in use, these two terms may be used as synonyms, or with different meanings, when talking about indications.

In the ‘‘NEWS’’ section

Waste-water treatment and penetrant testing

Penetrant Testing (PT) critics claim that this method is polluting and that it should be banned and replaced by Ultrasonic or Eddy current Testing!
However, as we have repeatedly stated, each method has its advantages and limitations: PT will not be wiped off, whatever some people’s view on the matter. Indeed, this paper shows that the treatment of rinsing/washing water from PT process lines is perfectly handled and that, therefore, PT is not a polluting method.

In the ‘‘Oldies but goodies’’ section

A developer that changed habits

For decades, NAWDs, for most of them, have been chlorinated solvent-based and packed in spray cans propelled with chlorofluorocarbons (CFCs).
Following the phase-out of CFCs and the requirements for extremely low levels of halogens in the aerospace and nuclear industries, other solvents and propellants were needed. This has somewhat modified the way a developer is applied.
By the way, we recommend that you read again our DPCNewsletter N° 035 of April 2011 titled ‘‘Penetrant Testing - Non-aqueous wet developer: how to apply a thin, even layer from a spray can?’’(Completed and updated in June 2011).

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.
