This part of ISO 28927 specifies a laboratory method for measuring handtransmitted vibration emission at the handles of handheld,
powerdriven, portable polishers and rotary, orbital and random orbital sanders used for
surfacefinishing processes, not for material removal. It is a typetest procedure for establishing the magnitude of vibration in the gripping areas of a machine when operating under typetest conditions. It is intended that
the results be used to compare different models of the same type of machine.
This part of ISO 28927 is applicable to handheld machines (see Clause 5), 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.
