Friction coefficient testing measures the resistance between two surfaces in contact—specifically, the static (when not moving) and kinetic (during sliding) friction. Industry standards like ASTM D1894 guide the process, commonly applied to materials such as plastics, films, rubber, paper, metals, and composites
