MARK-II Anti-Slip Testing Machine
The MARK-II Anti-Slip Testing Machine is designed to evaluate the static friction coefficient between shoe sole materials and floor surfaces. It uses an inclined-frame testing method to determine the frictional resistance of a specimen immediately before sliding occurs.
During testing, a cut specimen is attached to the test fixture and pressed against a horizontal floor surface under a specified load. The rotating support frame is gradually tilted, increasing the horizontal force acting on the specimen until it begins to slide. The static coefficient of friction is then determined according to the test method.
The instrument features a simple mechanical structure and a portable design. It is suitable for comparing footwear sole materials and evaluating their slip-resistance characteristics during product development and quality control.
