Vinyle Coefficient Of Friction

The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it.

Vinyle coefficient of friction.

Chemical resistance per astm f 925. A cof of 0 5 is not intended to be an absolute standard value. 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 cof of 0 zero means that there is no friction between the two surfaces.

Static friction is friction between two or more solid objects that are not moving relative to each other. In a nonmandatory appendix to a proposed rule in 1990 osha said a reasonable measure of slip resistance is static coefficient of friction scof is recommended as a guide to achieve proper slip resistance. Both the types of cof can be expressed by the same equation as. Solid vinyl floor tile page 1 of 5 parterre solid vinyl floor tile 4.

Static coefficient of friction per astm c 1028. Showing the concept of coefficient of friction. The static and kinetic friction coefficient values reference table shown in this article will be helpful for finding the cof values of commonly used materials. Cushioned flooring fetch content.

Vpi premium resilient tile. 12 x 12 24 x 24 36 x 36 inch static coefficient of friction 0 5 scof static coefficient of friction maximum static load 2 500 psi 1 500 psi construction doc retrieval. N normal force between the surfaces n lb there are at least two types of friction forces. F f frictional force n lb.

Static and kinetic coefficient of friction. The commonly specified and often misunderstood value of 0 60 static coefficient of friction scof determined by the astm c1028 test method has been superseded by a new method new test conditions and a new threshold value all of which can be found in the 2012 edition of ansi a137 1 the american national standard specifications for. Tile companies voluntarily subject their products to testing at independent laboratories which measure skid resistance. F f μ n 1.

For example static friction can prevent an object from sliding down a sloped surface. The coefficient of friction cof is the measurement of a surface s frictional resistance. The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. The frictional force can be expressed as.

A higher cof may be necessary for certain work tasks such as. Therefore for slip resistance purposes a higher number means the surface is less slippery when tested. μ static μ s or kinetic μ k frictional coefficient. Essentially this number tells you how slippery a surface is.
