Over deze norm
This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power driven percussive machines with and without rotary action (portable rock drills, plug hole drills, rotary hammers, breakers (e.g. pavement breakers, concrete breakers or road breakers), riveting hammers, chipping hammers, pick hammers, or similar). It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of machine fitted with inserted tool bit. This part of ISO 28927 applies to rotary percussive machines intended for making holes in hard materials like rock and concrete. It also applies to breakers intended to work downwards to break hard material like concrete, rock, pavement, asphalt, etc. and for hammers intend to work in any direction to perform riveting or chiselling work. The machines covered by this part of ISO 28927 may be pneumatically driven, or driven by other means. Typical machines are illustrated in Figures 1-7. This part of ISO 28927 applies to the machines mentioned in clause 5. It does not apply to impact drills with direct mechanical impact mechanisms. Also this standard does not apply to jack leg type rock drills and push feed rock drills which are hand guided (the feed force is not applied by hand, but by an additional device). It is intended that the results can be used to compare different models of the same type of machine.
