The test method consists in drawing a given block with definite speed over the test surface of in general rough structure. The bottom side of the block is covered with a layer of standard rubber to get comparable results.
Abstract
Overview
ISO 7176-13:1989 specifies a standardized test method to determine the of surfaces used for wheelchair testing. The method defines a repeatable procedure that uses a steel test block with a standardized rubber interface to produce comparable friction values for rough surfaces (typical of unfinished concrete) and other test surfaces used in wheelchair standards.
