Floor coefficient of friction (COF) testing is the measuring of the slip resistance of a flooring surface. The static coefficient of friction (SCOF) is the force required to start an object moving relative to the surface, divided by the weight of the object on the floor. It is a measure of the resistance to sliding […]

Maximum Coefficient of Friction is not Limited to 1.00
It’s sometimes assumed that coefficient of friction (COF) has a maximum theoretical and practical value of 1.00. This isn’t true; there is no maximum. It is true that values exceeding 1.00 are so slip-resistant that their actual value is often of little interest. Some COF measuring instruments, such as BOT-3000E and English XL, are not […]
A Review of Standards for Pedestrian Slip Resistance Testing
There are a number of floor slip test methods established by standards-setting organizations that assess pedestrian slip resistance. Here we’ll review the most widely known and current ones. They are distinguished by the devices used in the testing. Terms such as DCOF rating, coefficient of friction, slip coefficient, slip resistance rating, and friction coefficient all […]
New Study Shows Sotter Engineering to be one of World’s Most Accurate Pendulum Floor Slip Test Labs
A recent global interlaboratory program “Slip Resistance Proficiency Testing — Pendulum Friction Tester,” showed Sotter Engineering Corporation’s Safety Direct America (SDA) floor slip resistance testing laboratory to be one of the world’s most accurate in use of the pendulum skid tester. The pendulum is a national standard for pedestrian floor and tile slip resistance testing […]
