ANSI NFSIB-101.1-2009 pdf download American National Standard B101.1 Test Method for Measuring Wet SCOF of Common Hard-Surface Floor Materials
1.1 Scope
This test method specifies the procedures and devices used for both laboratory and field testing to measure the wet static coefficient of friction (SCOF) of common hard-surface floor materials.
1.2 Purpose
This test method provides a measurement procedure stting forth traction ranges that facilitate remediation of walkway surfaces when warranted.
1.3 Application This test method does not apply to carpeting of any type or mechanically polished tile such as polished porcelain, marble, etc., but does address the common hard-surfaced flooring materials such as ceramic tile, vinyl floor coverings, and wood laminates, as well as coatings, polishes, etc.
Note: This test method does nol purport 1o address all of the safery concerns, if amy, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. No express or implied representation or warranty is made regarding the accuracy or significance of amy test results in terms of slip resistance.
1.4 Exceptions This test method is not recommended for dry-surface testing and does not propose to be an accurate measurement method for determining dry-surface slip resistance. Dry-surface test data should not be compared to wet-surface data. No inferences should be implied or concluded regarding dry vs. wet SCOF test results or data.

3.1 Friction. Resistance to the relative motion of two solid objects in contact. This force is parallel to the plane of contact and is perpendicular to the normal force.
3.2 Grout Joint. The space between two (2) or more pieces of tile. This space may be fll or unfilled.
3.3 Grain. A characteristic of many natural materials such as wood that may exhibit directional bias as it relates to slip resistance.
