P4 Slip Rating Explained

Smooth natural stone, as slippery as glass, is the floor tile with the lowest coefficient of friction. DIN 51130 Shod-footed Inclined Ramp Test R10 (Medium Friction) – Application R10 (Medium Friction) – Suitable for dampening on residential flooring on a regular basis, e.g. Entrances that are likely to become wet during routine usage – A 39 pendulum test or an R11 ramp test is required in the entry and transition area of a public building. ABC Rating (Bare Feet) Ramp can also be used to evaluate floors in predominantly wet environments such as swimming pools or showers, providing an aABCa floor slip rating.


Test the floor with a tribometer (P4 slip rating) to find out if there is a high tendency to slip, if it is dry and/or (in most cases) wet with water or with other contaminants such as edibles Grease, hydraulic oil, etc. Many tribometers for testing the slip resistance of floors and laboratory devices for measuring static (stationary) and dynamic (moving) coefficients of friction are produced around the world, but only a few of them have proven to be reliable for obtaining results. Test Methods. The Occupational Safety and Health Administration (OSHA) recommends a SCOF of 0.50 for work environments, but floors that typically score 0.60 or higher (maybe more slippery than 0.50 floors) are supported by reliable testers (and suffer from many slip and fall accidents) ) will be very, very slippery when wet using this outdated test method. The modified test described in ANSI A137.1/A326.3 does not appear to be the case and should not be used solely to assess the slip risk of any floor covering.


Unfortunately, when manufacturers supply tiles, they can only list an aRa value and not a PTV value, making it very difficult to determine if a floor will be safe for its intended use. and also the surface of floors (eg marble floor) resists slipping better when dry, but much worse when damp or dirty. If the selected floor has a slip resistance rating of R11 but no PTV is specified, we recommend testing a sample of the floor. There is no direct comparison between these tests, which can be confusing when comparing a tile with one test result with a tile with a different test result, so to help you compare and choose the right type of tile for your floor, Mountain Tile details the classification on their website sliding DIN 51130 for our floor tiles. Non-slip floor tiles are assigned a strength rating to help classify a particular tile’s delayed level of anti-slip capability.


Floor tiles are usually assigned an R rating; this rating refers to the slip resistance of the tile and therefore will determine the specific end use of the tile. Generally, low-traffic or R-rated floor tiles are not suitable for high-traffic areas (especially public or commercial areas). Not all tiles will have a slip rating, but usually tiles designed to provide traction will. Each slip index is used to evaluate the surface friction characteristics under different environmental conditions.


The R rating runs from R9 (a tile with a higher risk of slipping) to R13 (a tile with a very low risk of slipping). The tile is then given a P-score, ranging from P0 (very high slip risk) to P5 (very low slip risk). Tile ratings, which specifically test the tile surface for slip resistance, are especially important to consider when the floor gets very wet. While it’s understandable that people choose the tiles they want to install in their kitchens, bathrooms, or even gardens purely for aesthetic reasons, it’s important to understand that most floor tiles are given a non-slip rating and that you should choose tiles with that rating. slip class suitable for the tiling site.


If handled improperly, tiles become particularly slippery when wet and dry, which can lead to serious slips and falls. Non-slip floor paint can also be used on many surfaces: wood, metal, concrete and asphalt. Floor surfaces such as natural stone and timber finishes will have a high R rating and high wear resistance. Due to their anti-slip properties, they can also be used as outdoor floor tiles (porcelain tiles only) or commercial tiles.


Slip resistance R10. R10 slip-rated options provide moderate to moderate slip resistance, making them ideal for use in hallways, kitchens and other living areas, including bathrooms. While the R9 and R10 values ​​are often used and recommended for household bathroom or kitchen tiles where there is less risk of slipping. The tile is assigned an “R rating” from 9 to 13 inclusive, with the highest score indicating more resistance. The table below shows the possible uses offered for tiles in each classification.


This classification was obtained by testing the tiles both dry and wet before laying. In addition to the above tests and slip resistance ratings, some tile collections will also include a V rating in their description. To determine the R rating of a tile, you need to test it with a linear test. The angle at which the tester stopped is then translated into an R score associated with the risk of a particular tile slipping.


After a series of repeated tests, this angle is averaged and used to determine the tile’s R rating. The wet oil slope test uses the same slope as the wet barefoot test, the test surface is coated with cladding timber oil instead of water, and the test subjects wear special test shoes. The Barefoot Wet Foot Ramp Platform Test uses a water-damped ramp platform to evaluate the slip resistance of a material on a walking floor surface. The pendulum test measures the frictional resistance between wet tile and a foot mass equipped with a rubber slider mounted on a swing arm that simulates the effect of a standard shoe sole on wet tile.


The Pendulum Slip Tester is also the basis for the Sustainable Slip Test Standard, which has been defined by McDonald’s restaurants since 2006 and helps architects and designers understand how slippery a particular tile will perform after a year or two of use. Use traffic. The pendulum is also an instrument used in a sustainable anti-skid test method, which measures the possible impact of years of use on the potential anti-skid performance of a pavement. Both the BOT-3000E and Tortus (see below) are capable of performing more slip tests per hour than a pendulum can, making these valuable tools for testing and/or comparing multiple sections of large floors fairly quickly. Different areas of the floor (for example, in high-traffic areas) vary. In most cases, a high friction floor will provide enough grip to prevent a person from falling, and HSE/HSL has determined that the likelihood of slipping is low on floors with a minimum slip resistance value (SRV) of 0.36 coefficient of friction (COF) One in ten thousand.
