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. This standard applies to shredders/chippers with feed intake
openings or segments, in this standard referred to as feed safety openings and being of any shape
complying with the safety distance requirements of this standard with regard to contact with the
cutting means, that in total will fit into a square of 250 mm × 250 mm measured at the plane of the
opening(s).
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 separate 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 powered and battery-powered shredders/chippers.
Environmental hazards and EMC have not been considered in this standard.
This standard deals with all significant hazards, hazardous situations and events relevant to
shredders/chippers, when they are used as intended (see clause 4).
This document is not applicable to shredders/chippers which are manufactured before the date of
publication of this document by CEN.
