What does DCOF mean in tile?
dynamic coefficient of friction
DCOF, or dynamic coefficient of friction, is a measurement that determines how much friction there is on wet, level floors when walked upon. The results of DCOF testing help us determine the likelihood of whether or not a tile surface could contribute to someone slipping and/or falling.
What is DCOF for shower floor?
0.42
There is little agreement on what is suitable, but it is normally accepted to have an average Coefficient of Friction rating of . 6 per ASTM C1028 or DCOF minimum of 0.42 per ANSI A137. 1 for wet and dry surfaces.
Is DCOF .42 slippery?
According to modern DCOF AcuTest results, receiving higher than a 0.42 DCOF rating on level surfaces means there is a high slip resistance potential and therefore a low probability of slipping.
What is the difference between COF and DCOF?
COF (Coefficient of Friction) is a numeric value that represents the amount of friction between two objects. DCOF (Dynamic Coefficient of Friction) specifically tests the friction of an object that is already in motion (kinetic).
Is a higher DCOF better?
Slip Resistance for Level Interior Floors Other situations, such as standing water, oil, grease, or other slippery substances, may require higher DCOF numbers. It is also important to point out that a DCOF of 0.42 doesn’t necessarily equate to a safe floor; nor does a DCOF below 0.42 indicate a dangerous floor.
Does porcelain tile get slippery when wet?
Ceramic and porcelain tile floors can be notoriously slippery. There is a reliable way to find out how slippery floor tile will be under both wet and dry conditions. It’s a slip resistance rating system called COF (or coefficient of friction) published by tile manufacturers.
What kind of tile is not slippery when wet?
Vinyl tile is a budget-friendly option, and some vinyl tile is slip-resistant. It is available in a wide range of colors, designs and patterns, and many styles feature a textured surface that provides effective traction. Vinyl can be customized to look like ceramic tile, wood, stone or other types of flooring.
What is the dynamic coefficient?
Dynamic Coefficient of Friction (DCOF) is the new industry standard for measuring a surface’s slip resistance and is quickly replacing Static Coefficient of Friction (COF) tests. DCOF measures slip resistance during motion while COF measure slip resistance to put an object in motion.
What are the ratings for a wet DCOF?
Wet DCOF Ratings Product Finish Wet DCOF Range Empire PO 0.22-0.32 Cross-Colors Mingles PO 0.31-0.41 Jazz Age UP 0.42-0.52 Story Teller UPS 0.42-0.52
What is DCOF acutest®?
It is the most accurate test to measure dynamic coefficient of friction on ceramic tile and meets ANSI A137.1 testing procedure. We no longer use SCOF testing because DCOF more realistically measures conditions of walking on tile. DCOF AcuTest® uses slightly soapy water instead of clean water to recreate environments where slipping occurs.
What is the DCOF standard for wet and level tile?
The DCOF AcuTest® has determined that 0.42 wet is the standard for tile that can be used in potentially wet and level applications. Dal-Tile Corporation recommends the following guidelines that shall be utilized along with a regular maintenance program: Public areas that are normally DRY, level, and contaminant free.
What is DCOF and why is it important?
WHAT IS DCOF? When it comes to tile and natural stone on the floor, slip-resistance is a main consideration, especially in bathrooms or industrial installations. DCOF, or dynamic coefficient of friction, is a measurement that determines how much friction there is on wet, level floors when walked upon.
