July 2012

1- Introduction

The contrast ratio is a topic rarely discussed in PT and MT training courses or documents. However, it is of the utmost importance for the detection of discontinuities in white light or under (UV-A) ultraviolet radiation.

Magnetic particle testing and the European Directive on the exposure of operators to low frequency magnetic fields (follow-up)

June 2012

We have to come back to this topic, as the implementation of the European Directive 2004/40/EC(1) has been postponed, and the threshold limits will be modified.

Further, is it useful to remind users, Occupational Medicine, Health and Safety responsible persons in companies, that since MT is widely used (i.e. back to the ‘30s), no correlation has ever been established between exposure to – for a long time and unknown – to magnetic fields and to any disease of the operators.

A help to choose the most suitable technique

April/May 2012

1- Introduction

Penetrant Testing is a Non-Destructive Method (NDT), simple in its principle, but, which requires following the rules to get reliable results.

You will find in this paper some useful advice. In no way, this paper can be considered as a standard or as a specification.

A help to choose the most suitable technique

March 2012

1- Introduction

Magnetic Particle Testing (MT) is a non-destructive testing (NDT) method used to detect surface-breaking or just-below-surface (generally down to some mm deep) discontinuities, only on ferromagnetic materials. This method requires following the rules to get the best results.

You will find in this paper some useful advice.

February 2012

This document is based on a conference given by George HOPMAN, in Las Vegas, on 13 November 2007.
It is important to know a bit more about this man, well known - and renowned - in the American NDT world. You may find his résumé at the end of this paper.

Time goes by and some things may have changed since this conference. What we wish here is to show "the critical thinking" we all of us shall continuously have: this is not always because one does "according to the relevant standards or documents" that one shall perform a successful inspection, i.e. finding the discontinuities that must be detected.
