In the October 2010 issue of the NDT Technician published by the ASNT (American Society of Nondestructive Testing), we have found a very interesting paper (1) that you may read.

It explains an MT technique using only one of the two legs of an AC hand-held electromagnet and which then produces a radial magnetic field.

It seems that, quite often, we “feel” what the topics of papers published in technical journals will be.

For instance, we wrote a draft, titled “Quality of some calibration services” in May 2010, about … well … the quality of the calibration/verification of UV-A irradiance meters, luxmeters and magnetic field meters.

Mid ‘80s, one of us was paying a visit to the plant of a large French metallurgical group.

He was told by the man who welcomed him that, quite recently, an American prime asked the question:

- "Are you metric?" which means: ‘‘Do you use the metric system?”

You bet the man was surprised: such a question by an American friend! Americans have not yet accepted the International System even nowadays!

The last PRI-NADCAP newsletter highlights some parameters of a PT line that are of the utmost importance. The topic is about the shape of the water flow, and water pressure is also mentioned. In some way, this newsletter substantiates our last month’s paper titled: “The water pressure: a myth?”

On May 22, 2010, we had the great pleasure to welcome a distinguished PT expert: William E. MOOZ, the very active life-blood of Met-L-Chek, a Californian company renowned the world over - at least in the PT world!  Bill Mooz was anxious to pay us a visit, and we deeply thank him for it.

We started our website exactly two years ago: our readership is far from what we anticipated! Never before we could have thought getting so precise and so many technical questions.

Every week we understand that NDT specialists are a bit “blown away”  by the "omnipotence" of "Quality Assurance specialists" when these "specialists" know so few about PT or MT technical requirements - just to talk about two methods we know some things about.

In our last month’s Editorial we asked for help by our readers about our mini-story “Forgotten old PT processes’’ published in the “OLDIES BUT GOODIES” series.

We were trying to understand why the ‘‘Wink fluorescent PT’’ is no longer in favour.

One of our readers sent us a message stating the winking method is not obsolete as a manufacturer markets a blue light searchlight with a blinking mode easing the indications detection, as written in our DPCNewsletter N°021 of February 2010 titled "Tomorrow's penetrants".
