NON-destructive testing: liquid penetrants

DETECTION OF SURFACE MARKS ON METALS

Our staff are qualified under ISO 9712 and SNT TC 1A in the penetrant method for detecting surface marks on all types of metal (welds, forged and cast products etc.) according to ISO and ASME standards.

Liquid penetrant testing can be of various types and the most commonly used are colour contrast and fluorescent.

The choice is made according to surface finish, type of mark, shape, and size of the mark to be displayed.
