Slip Meter Reports

To reduce risk exposure, agents and owners of commercial, industrial or public properties should have their flooring tested periodically for slip resistance.  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.

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.  Dividing the horizontal force by the vertical force (weight), we get a number called “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 the coefficient of friction is measured from a resting position, it is called the “Static Coefficient of Friction” (SCOF).  When it is measured when the surfaces are in relative motion, it is called the “Dynamic Coefficient of Friction” (DCOF).

Measuring the SCOF or DCOF can be achieved through the use of portable measuring devices or strict laboratory environment testing.  The higher the coefficient of friction (COF), the less slippery the surface.

What is a Slip Meter?

A slip meter is designed to quickly test 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 are the readings taken?

Readings are taken in four 90 degree directions, in the same spot.  The four readings are averaged, and this number is recorded as the coefficient of friction for this spot.  Readings are typically conducted on wet surfaces as the coefficient of friction drops dramatically when surfaces are subjected to water or other liquid spills.

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 expected to be walked upon when wet 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 or disabled), the turnover rate of maintenance personnel and other factors affecting risk. Together we will come up with a custom schedule to keep your floors safe.
