Introduction: Scratch Tester is applied to the scratch resistance performance evaluation of single coating or complex coating system in insulated color coated sheet. It will be known the coating scratch resistance performance by evaluating whether the coating is scratched by tungsten carbide hemispherical stylus with a certain weight or the maximum load of the coating which can not be scratched.

The Mechanised Scratch Tester is dedicated to coatings hardness evaluation based on the scratching resistance method.

A test panel is clamped and slowly moved whilst a stylus or alternative tool scratches the surface. Depending on test procedures, specified or variable loads can be applied to obtain different degrees of failure, from trace to destruction. A voltmeter indicates the contact of the tool with the metallic sample substrate. Max. panel size : 100x150x1.6mm (0.3mm coating).

The Mechanised Scratch Tester comes with the weight set required by ISO 1518-1. The weight set specified by the preceding international standard, ISO 1518, is optionally available
