The Coefficient of Friction- Is Your Business Compliant?

Coefficient of Friction

What is the coefficient of friction?

What is the coefficient of friction (COF)?

The coefficient of friction is a number that is used to determine the amount of slip resistance on a commercial, residential or industrial floor surface.

What is the minimum coefficient of friction required on a business floor surface?

Some regulatory agencies set requirements for the COF, others set recommendations. For example OSHA has a minimum COF requirement of .50. The Americans With Disabilities Act recommends a .60 COF for flat surfaces and a .8 COF for ramps. It is important to note that different testing devices produce varying testing results.

How is the coefficient of friction measured?

There are two ways to measure the COF:

1) From a resting position. This is called the Static Coefficient of Friction.

2) From a moving position. This is called the Dynamic Coefficient of Friction.

SlipStop Florida uses the Sellmaier FSC 2000 machine to measure the COF. The Sellmaier FSC is a portable device that measures both the static and dynamic friction levels.
