Measuring coefficient of friction.
Flooring friction coefficients.
The cof of two surfaces is the ratio of the horizontal or lateral and vertical or normal forces required to move one surface over another surface to the total force pressing the two surfaces together.
Cof slip resistance ratings help you determine if you are buying the right tile for the right location.
Slips and falls happen when the coefficient of friction cof between the two surfaces is insufficient.
Slip resistance testing or floor friction testing is usually desired by the building s owner or manager when there has been a report of a slip and fall accident when there has.
This coefficient is a measurement of the relative ability of various surfaces to resist the sliding or slipping of the selected material.
When it comes to flooring measuring the coefficient of friction helps to establish how safe a surface is.
There are standards that allow for these differences and safety direct america can supply the test data and safety standards to determine whether a particular flooring is appropriate.
Coefficient of friction cof is a mathematical term used to describe the effect of dragging one substance shoe sole material over another flooring surface.
Fpo katelyn simpson laboratory manager tile council of north america when it comes to coefficient of friction cof a measurement that relates to traction and tile.

Coefficient of friction is a common unit of measurement used to characterize the slip retardance of a surface.
Acutestsm determines dynamic coefficient of friction dcof with a sophisticated instrument called the bot 3000 a type of tribometer1 specific for flooring applications.
There is a reliable way to know how slippery floor tile will be under both wet and dry conditions.
Floor slip resistance testing is the science of measuring the coefficient of friction or resistance to slip accidents of flooring surfaces either in a laboratory before or after installation or on floors in situ.
A 2003 report by the society for protective coatings states that flooring with a high static coefficient of friction scof 0 8 to 1 0 is actually more of a slip and fall hazard because the roughness of the surface can catch the sole of footwear and cause the person walking on the surface to trip and fall.
Today tribometry figures heavily into floor safety.
Having the right amount of friction between the floor and the soles of the shoes of the person walking on it is essential.
