Sample Preparation

It is a common procedure to prepare coated test sheets for corrosion tests by applying various linear scoring marks in vertical, horizontal and intersecting forms in order to test the resistance of the coating system to sub-corrosion. For this purpose, in addition to the use of a test probe according to "van Laar" as a scribing tool, a test probe according to "Clemen" is often prescribed as a scribing tool. A single test probe for cross-cut tests is also occasionally used.

Erichsen offers instruments for sample preparation for corrosion tests such as salt spray tests, condensation water tests etc. Depending on the requirements to be fulfilled by the user, these test probes, which are to be used as scribing tools, are suitable tools for the preparation of defined scribing marks on paints/coatings in accelerated corrosion tests, such as condensation water, gas corrosion, salt spray, continuous or alternating immersion tests, short-weathering tests, etc.
