Slip Resistance -- Occupational Health & Safety
WebA low COF indicates smoother surfaces while a higher rating suggests that the surfaces are rougher and less slippery. In other words, a high COF will denote a low slip factor. According to ASTM, it is equally effective to use a stationary sled with a moving plane or a moving sled with a stationary plane when calculating COF. The new measurements in ANSI 137.1-2024 and ANSI A326.3 require that tiles wet with water have a minimum slip resistance of 0.42 DCOF. Keep in mind that this is a minimum level of slip resistance for level interior floors that are wet with water. Other situations, such as standing water, oil, grease, or other … Ver mais Prior to 2012, the coefficient of friction (slip resistance) for ceramic tile was tested using the method specified in ASTM C1028, which provided the Static Coefficient of Friction … Ver mais The device used to measure the new DCOF is called a tribometer and the most common device used is the BOT-3000. It is a fully automatic … Ver mais In 2012, the American National Standards Institute updated their ANSI 137.1 standard to change the measurement system for tile slip resistance to DCOF, or Dynamic Coefficient … Ver mais Unfortunately, there are no prescribed DCOF values for areas other than level interior floors since there are an infinite number of other conditions possible. For instance, wet ramps or auto mechanic floors where there is a … Ver mais chip tuning pdf
