Automatic scratches are used to measure the scratch resistance of the coating, and a half spherical pin with a diameter of 1mm (standard) is used to slowly contact the surface of the test and draw a 10cm long scratch.
Depending on the purpose of the test and the loading of the load, different degrees of penetration can be observed, from the surface trace to the complete penetration.
The motor drives the cutter lightly in contact with the sample, without the influence of the load (50-2500g) size, the needle is drawn on the sample, and automatically starts and stops.
The contact between the scriber and the metal matrix is identified by a voltmeter.
Used in GB/T 9279 "paint and varnish scratch test" and ISO 12137 "paint and varnishes" criteria.
