A floor is generally deemed safe if the scof measures 0 60 or higher.

Coefficient of friction for vinyl flooring.

Dcof rating for floors. The previously used test method astm c1028 standard test method for determining the static coefficient of friction of ceramic tile and other like surfaces by the horizontal dynamometer pull meter method was withdrawn in 2014 with no replacement. Posted on march 18 2018. 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.

Solid vinyl floor tile page 1 of 5 parterre solid vinyl floor tile 4. Static coefficient of friction per astm c 1028. Coefficient of friction is a common unit of measurement used to characterize the slip retardance of a surface. The most common measurement used in the united states today is the static coefficient of friction scof rating.

There is a reliable way to know how slippery floor tile will be under both wet and dry conditions. Cof slip resistance ratings help you determine if you are buying the right tile for the right location. In this test water was placed on the floor and a weighted plate with a sensor was placed over the water. Chemical resistance per astm f 925.

Astm c1028 coefficient of friction coefficient of friction test cof floor slip resistance standards osha osha slip test scof skid test. Prior to 2012 the coefficient of friction slip resistance for ceramic tile was tested using the method specified in astm c1028 which provided the static coefficient of friction scof. Cushioned flooring fetch content. 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.

The worst part of astm c1028 was it sometimes gave very high slip resistance ratings for floors. Cof or coefficient of friction slip ratings published by tile manufacturers. 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.

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.
