PT test panels: criteria for choosing ones for on-site use

July 2010

Having read the DPCNewsletter N°025 – June 2010: PT test panels: criteria for choosing ones for on-site use, one of our French readers, who works for a large prime in aerospace industry, sent us this message:

‘‘Reading this paper on test panels, I did not (or I failed to) see a sentence about the penetrant in opened tanks. In such a situation, the penetrant may become less sensitive; this could be a major reason to use test panels as those you described (PSM-5® or another one). I would like to know what you think on this topic if useful to you /your readers.”

Around 1970, I was a young sales engineer for an ET equipment manufacturer.

May 2010

Among the many questions sent us every month we have chosen two which will be of some
interest for you- at least we hope so!

Why a dry developer must be used only with a fluorescent penetrant?

Our answer comes as follows:

On our Website as in many PT training courses/documents, there is no clear explanation why a dry powder developer can be used only with fluorescent penetrants.
