Describes a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven, portable polishers and rotary, orbital and random orbital sanders used for surface-finishing processes, not for material removal.

This part of ISO28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven, portable polishers and rotary, orbital and random orbital sanders used for surface-finishing processes, not for material removal. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine when operating under type-test conditions. It is intended that the results be used to compare different models of the same type of machine.

This part of ISO28927 is applicable to hand-held machines (see Clause5), driven pneumatically or by other means. It is not applicable to straight grinders equipped with a sanding wheel or to belt sanders.

NOTE To avoid confusion with the terms “power tool?? and “inserted tool??, machine is used for the former throughout this document.
