Safety of household and similar appliances - Particular requirements for mains operated shredders and chippers
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. NOTE 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 1 Combustion 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 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.

Varnost električnih gospodinjskih in podobnih aparatov - Posebne zahteve za omrežno napajane drobilnike in sekalnike
Standard EN 50434 določa varnostne zahteve in njihovo preverjanje za načrtovanje ter konstrukcijo drobilnikov/sekalnikov z ročnim podajanjem in z vgrajenim električnim motorjem, katerih nazivna napetost ne presega 250 V pri eni fazi, z zbiranjem z vakuumom ali brez njega, ki so zasnovani za zmanjšanje organskih materialov na manjše koščke in se uporabljajo v stacionarnem položaju, z operaterjem, ki stoji na tleh. Ta standard velja za drobilnike/sekalnike s segmenti ali odprtinami za polnjenje, ki so v tem standardu poimenovane varnostne odprtine za polnjenje, ki skupaj ustrezajo kvadratu 250 mm x250 mm. V tem evropskem standardu se drobilnikom in sekalnikom skupaj reče stroji. Ta evropski standard ne obravnava zahtev za – stroje, ki jih napajajo motorji z zgorevanjem. OPOMBA 1: Stroji z motorji z zgorevanjem so obravnavani v standardu EN 13683; – stroje, ki jih poganja zunanji vir napajanja ali baterija; – stroje z motornim praznjenjem, ki so namenjeni raztresu materiala ali tovornim vozilom; – stroje z mehansko gnanim polnjenjem ali pritrditvami; – sekalnike lesa za uporabo v kmetijstvu, za trate, parke in gozdove; – stroje, ki se napajajo prek trifaznega napajanja. Ta evropski standard opisuje vsa večja tveganja, ki jih predstavljajo drobilniki/sekalniki, kadar se uporabljajo v skladu z njihovim namenom in pod pogoji razumno predvidene nepravilne uporabe. Elektromagnetna združljivost in okoljski vidiki z izjemo hrupa niso obravnavani v tem evropskem standardu. Ta evropski standard se ne uporablja za stroje, izdelane pred datumom, ko je CENELEC objavil ta dokument.

Foreword
This document (EN 50434:2014) has been prepared by WG 5, "Gardening appliances", of the
Technical Committee CENELEC TC 116, "Safety of motor-operated electric tools".
The following dates are fixed:
• latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2015-03-31
national standard or by endorsement
• latest date by which the national standards conflicting
(dow) 2017-03-31
with the EN have to be withdrawn
– alignment to the European Machinery Directive 2006/42/EC;
– alignment to EN 60335-1:2012.
This European Standard is to be used in conjunction with EN 60335-1:2012 “Household and similar
electrical appliances – Safety – Part 1: General requirements”.
When Part 1 is mentioned in this standard, it refers to EN 60335-1:2012.
This European Standard supplements or modifies the corresponding clauses in Part 1, so as to
convert that publication into the European Standard “Safety requirements for shredders/chippers”.
Where a particular subclause of Part 1 is not mentioned in this standard, that subclause applies as far
as is relevant. Where this standard states “addition”, “modification” or “replacement”, the relevant text
in Part 1 is to be adapted accordingly.
Compliance with the relevant clauses of Part 1 together with this European Standard provides one
means of conforming to the specified essential health and safety requirements of the Directive.
This European Standard follows the overall requirements of EN ISO 12100:2010.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association
