Scope: This test method specifies the procedures and devices used for both laboratory and field-testing to measure the wet dynamic coefficient of friction (DCOF) of hard-surface walkways.
Purpose: This test method provides a measurement procedure setting forth DCOF ranges which facilitate remediation of walkway surfaces when warranted.
Application: This test method does not apply to carpeting of any type, however, does address the common hard-surfaced walkway materials such as ceramic and porcelain tile, polished and un-polished concrete, stone, vinyl, wood and synthetic laminates, and such materials with coatings or polishes applied.
