8. Limits to the use of MT
Apart from the fact that MT is only applicable to ferromagnetic alloys, it has, like all other NDT methods, its own limitations of use.
8.1 Discontinuity not detectable by MT
Magnetic particle testing is a method for detecting surface discontinuities, both open and underlying (very close to the surface).
SCROLL TO TOPSome very open discontinuities will not be detected by MT, but will be visible to the naked eye. Indeed, as presented in the article...

Events
COFREND Days (French Confederation for Non-Destructive Testing) take place every three years in a French city chosen by COFREND. Those celebrating COFREND's 50th anniversary took place from May 30 to 1 er June 2017 at the Palais des Congrès in Strasbourg. The COFREND 2020 Days were cancelled due to the health and economic context, which had a strong impact on event activities in France....
