Slip Meter Readings and Reports

To reduce risk exposure, agents and owners of commercial, industrial or public properties should have their flooring tested periodically for slip resistance using a Slip Meter.  This will help verify that you are maintaining the optimum slip resistance for that flooring.  FCS Specialty Services Ltd. can conduct on-site testing and submit a written report that you maintain on file so you can prove you raised the coefficient of friction on your floors.

What is Slip Resistance?

Slip resistance friction or traction is the resistance to lateral movement caused by the contact between two surfaces.  Slipperiness = Too little friction.  If we divide the horizontal force by the vertical force (weight), we get a number known as “The Coefficient of Friction”  (COF).

What is the Coefficient of Friction?

The coefficient of friction (COF) refers to a measurement based on the force of friction a surface has.  The measurement ranges from 0 – 1.0.  The higher the measurement, the more friction there is on the surface and the less slippery it is.

When we measure the coefficient of friction from a resting position, it is known as the “Static Coefficient of Friction” (SCOF). When we measure the surface in motion, we call it the “Dynamic Coefficient of Friction” (DCOF).

To measure the SCOF or DCOF, we must use a portable measuring device or send it in for strict laboratory testing. The higher the coefficient of friction (COF), the less slippery the surface is.

What is a Slip Meter?

A slip meter tests the static coefficient of friction, using widely recognized test sensor materials, onsite.  It is important that the operator performing the test do so in a conscientious manner, understanding basic test methods and procedures.  By so doing, reliable results will be obtained.

How do we take the readings?

We take the readings in four 90 degree directions, in the same spot.  Then we average the four readings, and then record this number as the coefficient of friction for this spot.  The readings are always drawn on wet surfaces because the coefficient of friction drops dramatically when surfaces are wet.

What do the numbers mean?

The higher the measurement, the more friction there is on the surface and the less slippery it is.  All readings will fall into the following categories:

  • Dangerous:  .01 to .49
  • Caution:  .50 to .59
  • Safe:  .60 to 1.00

What is the Standard of the Coefficient of Friction?

 According to the ANSI A137.1-2012 standard, level interior spaces must have a minimum wet DCOF value of .42 which equates to a minimum wet SCOF value of .60.

How often should my floor be treated?

For some properties, quarterly testing is appropriate, while for others an annual test is adequate.  Many variables go into deciding frequency.  They include the number of pedestrians using the floor (with added consideration for the aged and disabled), the turnover rate of maintenance personnel as well as other factors affecting risk.  Together we can come up with a custom schedule so we can keep your floors safe.
