Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).
This adjustment allows the scale beam to be maintained in a level position in respect to the specimen and turntable. Designed with an integrated bearing, the scale beam can be tilted in a rest position enabling the operator to mount or remove specimens.
This test method is used to test the scratch resistance surface material refers to cause injury. According to the material may be exposed to the use of nails or other hard objects, using different materials scraping means, in accordance with the direction of travel, speed, a certain pressure is applied to the sample surface, scratches and samples head relative motion, resulting in one-way, non-linear reciprocating the wiping trajectory between parallel scratches. Final assessment grade material senses scratches, scratches and color difference regions, not scratches or sample surface area was damaged when the minimum scraping force.
