Friction scratch resistance test
The friction scratch test is a method to test the scratch and wear resistance of the material surface. The basic principle is to rub a hard object back and forth on the material surface with a certain force and speed, and then observe whether there are scratches or damage on the material surface. This test method is often used for quality inspection of various engineering materials, coatings and automotive paint.
During the test, it should be noted that the test parameters should be as close to the actual use conditions as possible, such as strength, speed, number of times, etc. At the same time, different test methods will also have different effects on the results, so the appropriate test method should be selected according to different needs.
What is the IEC 60335-1 standard?
IEC 60335-1 is a general safety standard for household appliances, which requires that household appliances must have good insulation performance and protective measures to protect the safety of consumers. The standard stipulates measures such as protection against electric shock, overload protection, radiation, toxicity and similar hazards, and also stipulates that the design and manufacture of household appliances should ensure safe and reliable operation in normal use, and even if there may be misoperation during use, it will not cause harm to users and the surrounding environment.
Scratch Resistance Test Machine
The scratch resistance test machine usually consists of a motor, a table and a fixed test arm. The test sample is placed on the table. The test arm moves slowly and applies a certain amount of friction to the sample surface. During the test, a magnifying glass or microscope can be used to observe whether there are obvious scratches or color differences on the sample surface. Based on the test results, information such as the sample’s friction coefficient, scratch depth, and surface damage degree can be obtained.
