Rolling resistances ISO2175 test conditions


Harder the wheel the lower the rolling resistance or force required to start and maintain a given movement and higher the load capacity. Hard wheels however can damage any surface if the wheel material is harder than the floor surface. Test period for wheel or castor should not show deformation which will interfere with continued operation. Actual laboratory conditions can last longer than normal operational conditions and as such should only been used for guide purposes. ISO2175 will not define life expectancy this an impractical measure as environments change
