Household and similar electrical appliances - Safety - Part 2-91: Particular requirements for walk-behind and hand-held lawn trimmers and lawn edge trimmers
This clause of Part 1 is replaced by the following. This European Standard specifies safety requirements and their verification for the design and construction of electric powered walk-behind and hand-held lawn trimmers and lawn edge trimmers, with cutting element(s) of non metallic filament line or freely pivoting non-metallic cutter(s), with a kinetic energy of not more than 10 J each, used by a standing operator for cutting grass, their rated voltage being not more than 250 V for a.c. or 75 V d.c.. NOTE 101 The method of calculating the kinetic energy for the purposes of this standard is given in 22.103. In this European Standard, hand-held and walk-behind lawn trimmers and lawn edge trimmers are referred to collectively as machine(s). This European Standard does not apply to - scissor type or lawn trimmers and lawn edge trimmers with cutting means other than those described above; - lawn trimmers and lawn edge trimmers with collecting devices; - self-propelled lawn trimmers or lawn edge trimmers; EMC and environmental aspects, except noise, have not been considered in this European Standard. This European Standard does not apply to chargers as covered by EN 60335-2-29. This European Standard does not apply to batteries as covered by EN 62133. This European Standard deals with all the significant hazards presented by hand-held and walk-behind lawn trimmers and lawn edge trimmers when they are used as intended and under conditions of misuse which are reasonably foreseeable.

Appareils électrodomestiques et analogues - Sécurité - Partie 2-91: Règles particulières pour les coupe-gazon et les coupe-bordures portatifs et à conducteur à pied
S'applique aux coupe-gazon et coupe-bordures électriques, portatifs et à conducteur à pied, comportant un ou plusieurs organes de coupe constitués d'un filament non-métallique ou d'une lame non métallique à pivotement libre, chacun étant caractérisé par une énergie cinétique infériure ou égale à 10 J, utilisés par un opérateur à pied pour couper l'herbe.
Gospodinjski in podobni električni aparati - Varnost - 2-91. del: Posebne zahteve za ročno vodljive in prenosne motorne kose za trate in robove trat
To točko 1. dela nadomešča naslednje besedilo.
Ta evropski standard določa varnostne zahteve in njihovo preverjanje za načrtovanje ter konstrukcijo električno gnanih, ročno vodljivih in prenosnih motornih kos za trate in robove trat, z rezalnimi deli iz nekovinskih niti ali prosto vrtečih se nekovinskih rezil, pri čemer nobeno nima več kot 10 J kinetične energije, ki jih uporablja stoječ upravljavec za košnjo trave, njihova nazivna napetost pa ne sme presegati 250 V izmeničnega toka ali 75 V enosmernega toka.
OPOMBA 101: Metoda za izračun kinetične energije za namene tega standarda je navedena v 22.103.
V tem evropskem standardu so prenosne in ročno vodljive motorne kose za trate in robove trat
označene s skupnim imenom stroji.
Ta evropski standard se ne uporablja za
– škarje ali motorne kose za trate in robove trat s sredstvi rezanja, ki niso
navedena v zgornjem besedilu;
– motorne kose za trate in robove trat z zbiralnimi napravami;
– samognane motorne kose za trate ali robove trat;
Elektromagnetna združljivost in okoljski vidiki z izjemo hrupa niso obravnavani v tem evropskem standardu.
Ta evropski standard se ne uporablja za polnilnike iz standarda EN 60335-2-29.
Ta evropski standard se ne uporablja za baterije iz standarda EN 62133.
Ta evropski standard obravnava vsa večja tveganja, ki jih predstavljajo prenosne in ročno vodljive
motorne kose za trate in robove trat, kadar se uporabljajo v skladu z njihovim namenom in pod pogoji razumno predvidene nepravilne uporabe.

When “Part 1” is mentioned in this standard, it refers to EN 60335-1:2012.
This document supplements or modifies the corresponding clauses in Part 1, so as to convert that
publication into the European Standard “Safety requirements for walk-behind and hand-held lawn
trimmers and lawn edge trimmers”.
Where a particular subclause of Part 1 is not mentioned in document, 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 document 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.
Warning: Other requirements arising from other EU Directives can be applicable to the products
falling within the scope of this European Standard.
The following numbering system is used:
– subclauses that are numbered starting from 101 are additional to those in Part 1;
– additional annexes are lettered AA, BB, etc.;
NOTE In this European Standard the following print types are used:
- requirements proper: in roman type;
- test specifications: in italic type;
- explanatory matter: in smaller roman type.
Words in bold in the text are defined in clause 3. When a definition concerns an adjective, the adjective and the associated
noun are also in bold.
