This European Standard specifies safety requirements and their verification for the design and construction of hand fed, shredders/chippers with integral power source and with or without vacuum assisted collection which are designed primarily to reduce organic material to smaller pieces. It is only applicable to shredders/chippers that are designed for use outdoors in a stationary position by an operator standing on the ground. It applies to shredders/chippers with feed intake openings in the form of a single opening or an opening divided into a number of segments. The feed intake openings or segments each being of any shape that will fit into a square of 250 mm × 250 mm measured at the relevant safety distance to the cutting means. NOTE Feed safety openings are limited to 250 mm × 250 mm but the total feed intake opening can be any size. This standard describes methods of elimination or reduction of hazards arising from the use of shredders/chippers. In addition it specifies the type of information to be provided by the manufacturer on safe working practices. This standard does not cover requirements for: - units driven by an external power source; - mobile use of units which can be used in both stationary and mobile modes; - units with powered discharge intended to broadcast material or load vehicles; - units with mechanically powered feed intake or attachments; - units with cutting means of either one or more non-metallic filaments, or one or more non-metallic cutting elements pivotally mounted on a generally circular central drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting means of less than 10 J; - electrical aspects of electrically driven shredders. Environmental hazards and EMC have not been considered in this standard.
