Terms and Definitions Friction The action of hindering the sliding of two contacting surfaces. Divided into kinetic friction and static friction. static friction static friction The moment the sliding begins, the &#8220;critical&#8221; friction that needs to be overcome. dynamic friction The friction that exists during sliding at a given velocity. frictional force The force required to overcome friction. It is divided into static friction force FS and dynamic friction force FD normal force normal force is the force applied perpendicularly to the two contact surfaces. FP friction coefficient coefficient of friction friction and normal force ratio. Static coefficient of friction static coefficient of friction\u03bcs=static friction FS\/normal force FP dynamic coefficient of friction \u03bcD=dynamic friction FD\/normal force FP Note 1: The friction coefficient of the film is usually between 0.2-1 Ideally, the coefficient is an inherent property independent of the test instrument and test conditions. Since the film is usually not ideal, GB\/T 10006-2021 specifies all test parameters.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5a54ea9 e-flex e-con-boxed e-con e-parent\" data-id=\"5a54ea9\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-fcc27cf elementor-widget elementor-widget-text-editor\" data-id=\"fcc27cf\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><strong>Test equipment <\/strong><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-d3c0ede e-flex e-con-boxed e-con e-parent\" data-id=\"d3c0ede\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-aaba6e2 elementor-widget elementor-widget-text-editor\" data-id=\"aaba6e2\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The test device consists of a horizontal test bench, a slider, a force measuring system and a drive mechanism that moves the two test surfaces on the horizontal test bench relative to each other.
