Coefficient of Friction (COF): ASTM® C-1028-89 is the standard test method for determining the static coefficient of friction of ceramic tile and other like surfaces by the dynamometer pull meter method. Static coefficient of friction is a term used in physics to describe the amount of force required to cause an object (shoe sole material) to start moving across a surface (flooring material). A higher coefficient indicates increased resistance of shoe sole material to start moving across a flooring material. As the degree of wear on the shoe and flooring material; presence of foreign material, such as water, oil and dirt; the length of the human stride at the time of slip; type of floor finish, and the physical and mental condition of humans. Therefore, this test method should be used for the purpose of developing a property of the flooring surface under laboratory conditions, and should not be used to determine slip resistance under field conditions unless those conditions are fully described.” Please consult ASTM® Standard Test Method C-1028-89 for a more detailed explanation of coefficient of friction and test methods.
The ASTM® procedure states that “the measurement made by this apparatus is believed to be one important factor relative to slip resistance. Other factors can affect slip resistance, such as the degree of wear on the shoe and flooring material; presence of foreign material, such as water, oil and dirt; the length of the human stride at the time of slip; type of floor finish, and the physical and mental condition of humans. Therefore, this test method should be used for the purpose of developing a property of the flooring surface under laboratory conditions, and should not be used to determine slip resistance under field conditions unless those conditions are fully described.” Please consult ASTM® Standard Test Method C-1028-89 for a more detailed explanation of coefficient of friction and test methods.
Note that the precision of this test as described in the ASTM® procedure indicates that the coefficient values can be expected to vary as much as 0.3. Since coefficient of friction is normally less than 1.0, test results will vary by more than 30%.
Also, the static coefficient of friction may vary within and between production runs because of the inherent characteristics of ceramic tile. Although ANSI® has not established a standard value for coefficient of friction, OSHA (Occupational Safety and Health Administration) has established a recognized industry of 0.5 (wet and dry) for slip-resistant surfaces. The Americans with Disabilities Act (ADA) recommends but does not require “a Static Coefficient of Friction of 0.6 for accessible routes and 0.8 for ramps” ADA does not specifically state that 0.6 is both a dry and a wet requirement.
It is important to note that any tile or other hard surface flooring can become slippery when wet or improperly maintained.
The coefficient of friction of all hard surface flooring materials, including ceramic tile, can be adversely effected by inadequate or improper maintenance, such as the use of unsuitable cleaning materials or procedures. The Florida Tile Care and Maintenance Brochure explains how to maintain your tile floor. For a copy of this brochure, see your Florida Tile Distributor or call Florida Tile at 1-800-352-8453.


DCOF AcuTest
In 2012, the method for measuring the coefficient of friction (COF) of ceramic tiles changed, as specified in the American National Standards Institute (ANSI®) national standard specifications for ceramic tile, A137.1. It changed from the ASTM® International test method C1028, which measures static coefficient of friction, to the test protocol provided in the A137.1–2012 standard in Section 9.6, known as 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 A137.1–2012 also allows the use of other equivalent tribometers. Wet measurements use 0.05% sodium lauryl sulfate solution to establish a thin film as would be present when a slip occurs. The precision, repeatability, and reproducibility of the DCOF AcuTest® protocol is provided in the A137.1– 2012 standard. The test was so named for easy recognition, and to distinguish it from other DCOF measurements using different instruments and/or protocols. The DCOF AcuTest® COF measurement is not a property of the flooring but rather a measurement of the interaction between the sensor, the lubricant, and the tile surface under controlled conditions. It is useful to allow comparison between surfaces or to evaluate how a surface has changed over time. However, while the DCOF AcuTest® can provide a useful comparison of tile surfaces, it cannot, nor can any other device, predict the likelihood a person will or will not slip on a tile surface. Because many variables affect the risk of a slip occurring, the DCOF AcuTest® measurement shall not be the only factor in determining the appropriateness of a tile for a particular application.
What is the required DCOF for ceramic tile?
According to the ANSI® A137.1–2012 standard, ceramic tiles selected for level interior spaces expected to be walked upon when wet must have a minimum wet DCOF AcuTest® value of 0.42. Tiles with a lower value are not necessarily restricted to dry areas only, but rather are restricted to applications where they are kept dry when walked upon. In the case of residential bathrooms, the common use of bathmats can accomplish this. Similarly, in entranceways, the use of entrance mats can accomplish the same. tcna technical bulletin | 3 Not all products with a DCOF AcuTest® value over 0.42 are suitable for all applications. Type of use, traffic, contaminants, maintenance, expected wear, and manufacturer’s guidelines and recommendations are important and must also be considered by the specifier. Section of ANSI A137.1–2012 explains this in greater detail and should be reviewed carefully by anyone involved in the specification process before picking the right tile for their next project!


Moh’s Hardness: Scratch resistance of glazes is measured by scratching the glaze with a mineral of known hardness. Hardness of minerals is classified by Moh’s Scale, which lists 10 minerals according to their hardness. Each mineral in this scale will scratch those with lower numbers in the scale, but will not scratch minerals with higher numbers. Talc is classified as number one on the Moh’s Scales and diamond ten. Resilient flooring materials, such as vinyl and asphalt tile, are relatively soft and can be scratched by talc, number one on the scale. White polished marble can be scratched by calcite, which is number three. Black marble rates a four and can be scratched by fluorite. Most glazes used on ceramic tile fall in the five to six range, which is also slightly harder than most steels. Case-hardened steel, such as what is used in drill bits used for drilling holes in steel, is approximately six and will scratch most glazes. Some glazes used on ceramic tiles, designed for floor use, cannot be scratched by a case-hardened drill bit. Quartz, number 7 on Moh’s Scale, will scratch most glazes and all but the hardest unglazed ceramic tiles. Sand is a common example of natural quartz.


Breaking Strength
Breaking Strength: ASTM® C-648 describes the standard test method for determining structural strength of ceramic tile. This test provides a means for establishing whether or not a lot of ceramic tile meets the strength requirements which may be required for a specific installation procedure and its ability to withstand load and impact. The ANSI® standard requires an average breaking strength of 90 lbs. for wall tiles and 250 lbs. for floor tiles. Tiles installed on floors with adhesives may require higher breaking strengths.


Acid Resistance
Acid Resistance: ASTM® C650 is the standard test method for determining resistance of ceramic tile to chemical substances. The glazed surface of Florida Tile products is resistant to virtually all caustic and corrosive liquids. Typical exceptions are: fluorides and concentrated hydrochloric acid.


Freeze-Thaw Resistance
Frost Resistance: ASTM® C-1026 describes the standard test method for determining ceramic tile’s ability to withstand repeated cycles of freezing and thawing. Ability of tile to resist damage or deterioration when tested in freezing and thawing situations such as those found in central and northern sections of the United States.
The use of Florida Tile products are not recommended for exterior horizontal surfaces.
Florida Tile Product Information: Florida Tile products are glazed, high-strength, flat-backed tiles. All Florida Tile floor tile products are made by the “single-fired” process, which generally imparts superior impact resistance and superior breaking strength. All products are formulated using high quality clays, specifically designed for density and strength then pressed, glazed and fired. Note that the data represented in this literature represents typical test results of randomly selected “standard” products.


Shade Variation
Shade and texture variations are inherent in these nature-inspired products. These types of tiles are packed by shade blends and not specific shades. Products of a common shade blend type may be used together. Specific product lots are identified by the last letter of the shade code.

V1 Uniform Appearance: 
Version1Differences among pieces from the same production run are minimal.

V2 Slight Variation: 
Version2Clearly distinguishable differences in texture and/or pattern with similar colors.

V3 Moderate Variation: 
Version3While the colors present on a single piece of tile will be indicative of the colors to be expected on the other tiles, the amount of colors on each piece may vary significantly. For example "that little bit of color" on one piece of tile may be the primary color on the next piece.

V4 Random Variation: 
Version4Random color differences from tile to tile, so that one tile may have totally different colors from that on other tiles. Thus, the final installation will be unique.



Note: In Order to provide as many size formats as possible, some sizes may be originally pressed as larger formats and then professionally cut to size.
