This European Standard specifies safety requirements and their verification for the design and construction of hand fed, shredders/chippers with integral electric motor, not exceeding 250 V single phase, with or without vacuum assisted collection which are designed to reduce organic material to smaller pieces and are used 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 that in total will fit into a square of 250 mm x 250 mm.

– machines with powered discharge intended to broadcast material or load vehicles;
– machines with mechanically powered feed intake or attachments;
– wood chippers for agricultural, lawn and park and forestry use;
NOTE 2 Wood chippers are covered by EN 13525.
– machines powered from a 3 phase supply.
This European Standard deals with all significant hazards presented by shredders/chippers when they are used as intended and under conditions of misuse which are reasonably foreseeable.
EMC and environmental aspects, except noise, have not been considered in this European Standard.
This European Standard is not applicable to machines which are manufactured before the date of publication of this document by CENELEC.
