What is a DCOF rating for flooring?
DCOF Rating for Floors. As such it can provide a useful comparison of surfaces, but does not predict the likelihood a person will or will not slip on a hard surface flooring material .” This means that this DCOF rating is not an assessment of real-world slip risk, but rather a way to compare surfaces to one another.
What is the DCOF test for tiles?
To paraphrase the standard, the DCOF test only applies to interior level surfaces expected to be walked on when wet. It does not cover tiles installed on exterior applications, sloped surfaces, areas exhibiting poor drainage, or polished products.
What is the minimum DCOF value of ceramic tiles?
According to the new standard, ceramic tiles used in interior spaces that will be walked upon wet must have a minimum DCOF value of 0.42.
What is the minimum DCOF value and how does it compare?
What is the required minimum DCOF value and how does it compare to SCOF values? According to the new standard, ceramic tiles used in interior spaces that will be walked upon wet must have a minimum DCOF value of 0.42.
What does DCOF mean in tile?
dynamic coefficient of frictionThe coefficient of friction (COF) and the dynamic coefficient of friction (DCOF) slip ratings can tell you how slippery a tile will be in a variety of conditions.
What is a good DCOF for a shower floor?
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.
What is DCOF code?
The code specifies a minimum wet dynamic coefficient of friction (DCOF) of 0.42 “for tiles in level interior spaces expected to be walked upon wet.” The test uses a hard rubber slider to simulate the heel of a dress shoe. Does this mean that a tile is safe if it has a wet DCOF of at least 0.42?
What DCOF is considered slip resistant?
Slip Resistance for Level Interior Floors 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.
Is higher DCOF better?
Slip-resistant This rating is called the Dynamic Coefficient of Friction (DCOF). 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 kind of tile is not slippery when wet?
Terracotta tile, quarry tile, and brick have high COF ratings, so they are very slip resistant. Honed natural stone, slippery like glass, is one of the lowest COF-rated floor tiles.
How is DCOF measured?
What is the DCOF AcuTest? The DCOF AcuTest is an evaluation of the COF of a tile surface under known conditions using a standardized sensor prepared according to a specific protocol. Measurements are made with the BOT-3000, an automated and portable device that measures DCOF. The ANSI standard A137.
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).
What is the standard for slip resistance?
“Slip resistance” is defined under ASTM C 1028 as being 0.6 (level) – 0.8 (ramp) with a wet testing surface.
Are porcelain tiles slippery when wet?
In summary, outdoor porcelain does become a little slippery when it is wet or with snow, but not any more slippery than you'd find with a flamed granite or a traditional concrete paver.
What is DCOF testing?
The results of DCOF testing help tile manufacturers to determine the probability of whether a tile could contribute to someone slipping or falling. By knowing the DCOF of the tiles, one can determine with mathematical and scientific certainty which tiles are safer. DalTile also recommends that customers have tiles independently tested to determine if their products meet the requirements prior to product selection.
Why is Daltile slippery?
DalTile recommends regular and proper maintenance to avoid extreme changes. Improper maintenance can result in a build-up on the surface of the tile causing the tile to be slippery. If you have concerns regarding traction, consider testing the surface with a slip meter to determine the traction in those slippery area.
