They state that the possibility of a slip may be affected by: The material of the shoe sole and its degree of wear The speed and length of stride at the time of a slip The physical and mental condition of the individual at the time of a slip Whether the floor is flat or inclined How the surface is used How the tile is structured How drainage takes place if liquids are involved ANSI and TCNA give no guidance as to how all of these items should factor into a higher DCOF or slip resistance, if needed, and most flooring manufacturers give no slip resistance guidelines or recommendations whatsoever. C was withdrawn by the ASTM in since it was a very bad test that was basically responsible for thousands upon thousands of needless slip and fall accidents across the country annually by spreading misinformation about the actual real-world slip resistance of various flooring materials. Do you duly consider all of the above 16 listed items when you specify, buy or sell flooring? Does anybody? Certainly these published lists can expose people on the buying side, and perhaps in the whole chain of supply as well, to accusations of negligence.

ANSI A History of Ceramic Tile Ceramics date back to antiquity , with clay figurines being contemporary to the cave paintings of Lascaux. Sometime later, ceramics were utilized for pottery. Ceramics are not inherently water-resistant, even though ceramic tile is often utilized with this quality in mind. In fact, the waterproofness of ceramic tile derives from several treatment processes of the material, particularly glazing or firing.
Ceramic tiles are available in an assortment of different types with varying characteristics, including glazed wall, mosaic, quarry, pressed floor, porcelain, and specialty tile.
For example, porcelain tile is defined, in accordance with ASTM C , as ceramic tile that has a water absorption of 0. In describing the available sizes and shapes of ceramic tile, as well as their physical properties, the basis for acceptance methods, marking and certification, and definitions, the American National Standard helps to guide producers in maintaining quality control while manufacturing ceramic tile.
Shapes, sizes, and grades of ceramic tiles are the primary categories for classification. Several procedures exist for testing ceramic tile in the standard, such as that for establishing water absorption ranges.
