Coefficient of Friction Tester GM-4 with heating function Standard ISO 8295, ASTM D1894, TAPPI T816, GB 10006 Introduction The coefficient of friction tester GM-4 is a measuring instrument developed and manufactured by the GBPI R&D team based on various test standards of GB, ISO, ASTM and market demand. The measured friction coefficient can accurately determine the smoothness, ease of opening and uniformity of the film, so as to guide the production correctly. It is suitable for measuring the static friction coefficient, dynamic friction coefficient and peel strength of plastic films, composite films, aluminum foils, aluminized films, plates, rubber, ceramics and other materials when sliding. Test Principle Clamp the strip test sample, and wrap the slider with the sample to be tested, and then place the slider on the hanging hole of the sensor. Under a certain contact pressure, the conveyor belt is driven by the motor to move the force sensor. That is, to move the two test surfaces relative to each other. The force signal measured by the force sensor is amplified by the integrator and sent to the recorder, and the kinetic friction coefficient and the static friction coefficient are recorded respectively.
