ISO 28927-5:2009 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven drills and impact drills. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a drill fitted with a drill bit. It is intended that the results be used to compare different models of the same type of machine.
ISO 28927-5:2009 is applicable to straight drills, drills with a pistolgrip and angle drills intended for drilling holes with rotating or impact action in all kinds of materials (see Clause 5), driven pneumatically or by other means. It is not applicable to heavy-duty drills with a screw feed or drills driven by a combustion engine.
