Shoe Outsole Slip Resistance Tester
1. Product Introduction & Applications
The Shoe Outsole Slip Resistance Tester is designed to measure the slip resistance of footwear and heel materials under conditions that closely simulate real-world walking. Extensive biomechanical research informs the design, ensuring test conditions reflect the moments during a step when slipping is most likely to occur:
Slip is most likely shortly after heel strike and just before toe lift, when half of the body weight is applied on the toes.
The equipment measures friction and slip resistance between shoe soles/heels and the floor surface.
Applications:
Footwear safety testing for chefs, nurses, industrial workers, and other professionals exposed to slippery environments.
Laboratory and quality control evaluation of slip-resistant shoe designs.
Comparative assessment of different sole materials against standardized flooring surfaces.
Performance verification for claims of “slip-resistant” footwear.
Working Principle:
The machine lifts the heel while keeping the toes on the ground, simulating the phase of a step most prone to slipping. A variable speed motor and a precision control system regulate the movement and forces applied to produce accurate friction coefficient measurements.
The tester supports standard calibrated flooring, and additional floor types can be used if compatible. Both footwear and floor materials can be evaluated against each other.
2. Conformity Standards
The tester is designed to provide measurements comparable to recognized slip resistance testing standards:
