Replacement:
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.
For the requirements for the measurement of the square of 250 mm x 250 mm are given in clause 20.101.1 of this standard.
In this European Standard shredders and chippers are referred to collectively as machine(s).
This European Standard does not cover requirements for
-
machines powered by combustion engines;
NOTE 1Combustion engine driven machines are covered by EN 13683 .
-
machines driven by an external power source or by battery power;
-
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 2Wood 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.

7 | Introduction This document is a type C standard as stated in EN ISO 12100:2010. The machinery concerned and the extent to which hazards, hazardous situations and events are covered is as indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the other standards, for machines which have been built and designed to the provisi… |
