SCOF- Static: Measures the amount of force required to initiate movement or cause slipping when a person is standing still on a surface. It is important to note that standards for measuring SCOF have all been withdrawn. DCOF- Dynamic: The dynamic (or kinetic) coefficient of friction (DCOF) is the measure of the resistance to
PTV stands for the Pendulum Test Value, a measurement of how slippery a surface is, measured with a tribometer called the British Pendulum, which stimulates a foot swinging across a surface.Check out the graphic below to understand where your PTV should be at in order to be considered in the 'Low Slip Potential' category.
Yes, our testing concludes with a legal document that is in accordance with both the ASTM F1694-14 "Standard Guide for Composing Walkway Surface Investigation, Evaluation and Incident Report Forms for Slips, Stumbles, Trips and Falls" and the ASTM F2048-00 "Standard Practice for Reporting Slip Resistance Test Results." Our testing follows the Daubert Principle and therefore
Static friction is friction that occurs between two bodies in contact with one another while they are at rest. It’s friction which prevents an object from moving while it is still. Dynamic (or kinetic) friction is friction that opposes the movement of a body which is already in motion. It’s friction that slows or stops
We are able to provide testing for the following standards: ANSI A326.3 (DCOF) ANSI A137.1 (DCOF) NFSI B101.1 (SCOF) ASTM E303 (PTV)* Please note that classifications under the ASTM E303 Test Method is also compatible with the following international standards: CEN/TS 1615:206 BS 7976-2:2002+A1:2013 We test using the BOT-3000e and the British Pendulum Skid Tester.
According to a study done by CNA Insurance, 50% of all floor surfaces in the United States are under the ANSI A326.3 standard of interior, wet dcof value of 0.42. We recommend you use the ANSI A326.3 standard to monitor and track your dcof levels. If you are concerned with slip potential, we recommend you
