Micom offers ASTM C1028 – Standard Test Method for Determining the Static Coefficient of Friction of Ceramic Tile and Other Like Surfaces by the Horizontal Dynamometer Pull-Meter Method. This test method is offered as part of the Micom material testing service offer. The coefficient of friction (COF) defines the ratio between the force required to put an object in motion and the force exerted on it, resulting from the gravity. Consequently, a COF close to “0” refers to slippery surfaces whereas a COF near “1” refers to high friction surfaces. It is generally accepted that a coefficient of friction of 0.5 or above is relatively safe on a surface.
Determining the Static Coefficient of Friction – Use and factors to be considered:
ASTM C1028 purports to determine the static coefficient of friction of surfaces in both dry and wet conditions. Though it has been found more appropriate for laboratory testing conditions, ASTM C1028 can also be used on site where the surface to be tested is not movable. Overall, the test consists of applying a horizontal force on a specific sled assembly until movement is achieved; the maximum recorded force is part of the COF calculation.
The Coefficient of Friction is believed to be an important factor relative to slip resistance on surfaces used in public areas. Slip resistance can be affected by different factors such as floor material, floor finish, presence of foreign material like water, oil and dirt, length of human stride, slip duration as well as the human physical and mental conditions.
