SSPC Guide 21

This guide collects information on various standards for evaluating slip resistance into a single document to assist owners and specifiers who must specify required slip resistance for a floor surfacing (or coating) in a given service environment. It contains recommended maintenance protocols for hard flooring surfaces to increase slip resistance, and a sample form that can be used to investigate accidents and determine corrective actions. Explanations of terminology related to slip resistance, descriptions of standard methods and testing equipment for assessing slip resistance, and considerations when interpreting test results are also included.
