Coefficient Of Friction For Vinyl Flooring

Coefficient of friction is a common unit of measurement used to characterize the slip retardance of a surface.

Coefficient of friction for vinyl flooring.

In dcof rating floor slip resistance safety standards osha slip resistance standard ramps or inclined surfaces slip resistance testing slipping accident prevention. Cof or coefficient of friction slip ratings published by tile manufacturers. Cof slip resistance ratings help you determine if you are buying the right tile for the right location. Cushioned flooring fetch content.

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. Dcof rating for floors. A floor is generally deemed safe if the scof measures 0 60 or higher. Astm d 2047 static coefficient of friction 0 75 astm d 2240 hardness shore d 59 5 astm d 3389 abrasion resistance h 18 500 g 1 000 cycles sheet vinyl floor covering 0 7 mm type i grade 1 wear layer astm f 1700 solid vinyl floor tile class iii type a or b fetch here.

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. 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. This is the standard set by the ada american disability act and it s what the majority of companies throughout the united states and canada run with.

Posted on march 18 2018. In this test water was placed on the floor and a weighted plate with a sensor was placed over the water. Static coefficient of friction per astm c 1028. The most common measurement used in the united states today is the static coefficient of friction scof rating.

Chemical resistance per astm f 925. The worst part of astm c1028 was it sometimes gave very high slip resistance ratings for floors. Solid vinyl floor tile page 1 of 5 parterre solid vinyl floor tile 4. 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coefficient of friction of ceramic tile and other like surfaces by the horizontal dynamometer pull meter method was withdrawn in 2014 with no replacement.

The latest american slip test for floors is the dcof rating test method specified in ansi a326 3 although this test is a much better test than the now withdrawn.
