How Do You Measure Slip Resistance In Barefoot Situations?

The UKSRG guidelines cover the use of the pendulum for barefoot areas. The guidelines detail a secondary rubber slider which is used to assess barefoot slip potential in wet conditions. The use of Rz microroughness measurements to supplement pendulum measurements is equally valid for barefoot situations. There are two standards for barefoot testing, but both are laboratory based, and so can not be used to assess installed flooring.
