How is "slip resistance" measured in tile?

Slip resistance in tile is measured using the Coefficient of Friction (COF) test. This test helps determine how much friction is generated between the surface of the tile and a person’s shoe. A higher COF indicates greater slip resistance, making the tile safer for walking or standing, particularly in wet or slippery conditions.

This method is crucial in assessing the safety of flooring materials in various environments, such as residential homes, commercial buildings, or outdoor spaces. The COF value is often used to meet regulations and standards for public safety, especially in areas where slipping hazards are a concern.

In contrast, tensile strength measurement pertains to the ability of a material to withstand tension and does not relate to slip resistance. Visual inspection alone does not provide a quantifiable analysis of slip resistance and can be subjective. Water absorption tests measure the porosity of tiles but do not assess how well they resist slipping, meaning they don't directly correlate with slip resistance.
