This is a not-so-easy-to-answer question, often asked, especially by users of Penetrant Testing installations. The answer could be used as well for Magnetic Particle Testing, and, very likely, for any other NDT method.

NADCAP has clarified the situation.

As per the NADCAP auditors, the term "Reference Picture Baseline" refers to the picture of a BRAND-NEW test panel. This reference picture baseline shall be used as such, as long as the involved reference panel is used.

As our readers know well, the writers of this Website, dedicated to all aspects of Penetrant Testing and Magnetic Particle Testing, are experienced Engineers.

Experienced men: that means that we have worked in these NDT methods for quite a long time, in fact, for almost four decades…implying that we are now in the exciting and restless third part of our life.

We do have friends who are even more experienced than us in this area, and are still active. We like sharing pieces of information with them. Their practical experience and skills are of the utmost importance to the NDT community.

In some American papers, standards and specifications, we see the terms "visible dye", "visible penetrant", "fluorescent dye" and "fluorescent penetrant". The definitions of some of these terms are given in the ASTM E1316 standard.

In the ISO standards, we see the terms: "colour contrast penetrant" and "fluorescent penetrant". The definitions of these terms are given in the ISO 12706 standard.
Any time, in France, we called the first ones: "pénétrants colorés", which means "coloured penetrants".

This paper, though published on a website specifically dedicated to Penetrant Testing and Magnetic Testing, does not deal with one of these methods.
Indeed, it won’t even deal with any NDT method.

Its topic: Quality Assurance.
However, when you read it, we are sure this story will make you think about very similar occurrences, linked, or not, to NDT.
