DIN EN ISO 28927-11:2011-05

This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held stone hammers. It is a type-test procedure for establishing the magnitude of vibration which must be stated in the instruction manual. This Standard applies to engraving pens and stone hammers intended for use by stone masons. It does not apply to demolition hammers or to chipping hammers primarily intended for use on metal or in construction. The machines covered by this part of ISO 28927 may be pneumatically driven, or driven by other means.
