This International Standard specifies a method of test for the slip resistance of PPE footwear including overshoes such as electrically insulating overshoes, which are worn over other footwear. It is not applicable to special purpose footwear containing spikes, metal studs or similar. NOTE 1 Footwear claiming slip resistance would be deemed an item of personal protective equipment. NOTE 2 For product development purposes, sole units, outsoles or other soling components such as top pieces may be tested.
