Responses: History of the Specification for Qualification of Penetrants, Singapore Air Show 2016

It is always interesting to see what issues of “The Penetrant Professor” stirs response from the readers. The January 2016 issue, which dealt with the history of the specification for qualification of penetrants prompted numerous emails from readers.

From a retiring government practitioner, Lisa, I will be leaving this office next week, please discontinue the Pen Prof; it’s been a great publication.

From a Canadian Quality Director,  “Thank you Lisa for continuing to copy me. I look forward to these newsletters. They really are little gems to those working the penetrant process. The insight, helpful hints and spec. interpretations are so helpful.”

From a Test Lab Level 3,“ Great read.”

From a retired aeroengine OEM Corporate Level 3, “Great job and great history lesson!!! I sure do remember participating in the round robin test and trying to arrange the sensitivity level of a penetrant using different testing methods. If I remember correctly, none of us got it right. We all had come up with different results. Some were close but none of us got the, “YA GOT EM”. Grover Hardy had a great sense of humor. This is one issue that people need to keep in their archives.”

We even had one of our French competitors ask us to include their employees on our mail list. Interesting, very interesting. Thanks to those who responded. If any of you have some hands on insights, tricks, or problem solving solutions please let us know and share with your fellow practitioners.

The Singapore Air Show is the largest aviation event in Asia. Met-L-Chek will participate in support of its’ Asian aerospace distributor McGean Cee-Bee Aviation. The CeeBee Singapore operation has been instrumental in growing Met-L-Chek’s market share in South East Asia and particularly in China. Their success was highlighted in the September 2014 Penetrant Professor. Also in attendance will be Cee-Bee Middle East which is also very active with Met-L-Chek.

Then & Now

One never knows or can anticipate what is liable to show up in the mailbox, whether it is an old fashioned mail box or an email mailbox. We
recently received an email asking if we could advise when the aerosol cans pictured below had been manufactured. A bit of research indicated
that they had been produced in late 1974 or early 1975. To add to this, the cans were still pressurized and functional.
