MR Chemie India Pvt. Ltd.

Penetrant Testing acc. to EN ISO 3452-1:2013

The liquid penetrant test method is used in the examination of welding seams, cast pieces, in shipbuilding, automobile and aircraft construction, apparatus and tank construction, etc.

Liquid penetrant inspection can be carried out with at daylight visible (red dye penetrant) and/or under UV-light fluorescent penetrants.

The PT method is charactestic for the fact that, contrary to the magnetic particle inspection (MT), defects or discontinuities can be proven also on not magnetizable materials.
