ASTM International is developing a proposed standard for measuring the traction of pedestrian walkways, including in wet conditions.

The proposed standard (WK60578) covers the use of variable-angle tribometers, which are a particular configuration of devices that measure friction. The standard is being developed by the traction subcommittee of ASTM International’s committee on pedestrian and walkway safety and footwear (F13).

The proposed standard will cover testing under wet walkway surface conditions. There are currently no ASTM test methods for using modern portable tribometers to test walkway traction.

Once approved, organizers say that the standard could be referenced in other planned ASTM International standards on tribometer validation to human reference standards, traction thresholds, flooring traction ratings and bathing surface traction.
