Household and similar electrical appliances - Safety - Part 2-92: Particular requirements for pedestrian-controlled mains-operated lawn scarifiers and aerators

Deals with the safety of pedestrian-controlled mains-operated electric lawn scarifiers and aerators. These scarifiers have rotating cutters for regenerating lawns by, for instance, combing out grass thatch and moss, or by cutting vertically into the lawn face. These scarifiers are designed primarily for home use, with a rated voltage not more than 250 V single phase. For lawnmowers, see IEC 60335-2-77; for lawn trimmers, see IEC 60335-2-91. The contents of the corrigendum of May 2003 have been included in this copy.

Gospodinjski in podobni električni aparati - Varnost - 2-92. del: Posebne zahteve za ročno upravljane rahljalnike in prezračevalnike travne ruše, priključene na električno omrežje

To točko 1. dela nadomešča naslednje besedilo.
Ta evropski standard določa varnostne zahteve in njihovo preverjanje za načrtovanje ter konstrukcijo ročno upravljanih rahljalnikov in prezračevalnikov, priključenih na električno omrežje, v nadaljnjem besedilu: »stroji«, ki so zasnovani za obnavljanje trate, in sicer na primer z izčesavanjem trave, slame in mahu ali navpičnim rezanjem v površino trate z uporabo zobcev, ki se vrtijo okoli vodoravne osi. Ta standard se uporablja v povezavi s 1. delom.
OPOMBA 1: Rahljalnikom zemlje se reče tudi grablje za trato.
Ta evropski standard se ne uporablja za nenapajane rahljalnike in prezračevalnike, baterijsko napajane rahljalnike in prezračevalnike, rahljalnike in prezračevalnike z navpično osjo ali tiste prezračevalnike, ki režejo v zemljo
s povratnim gibanjem, ter stroje s sedežem.
Ta evropski standard se ne uporablja za
– vrtne kosilnice (EN 60335-2-77);
– motorne kose za trate (EN 60335-2-91);
– motorne kose za robove trat (EN 60335-2-91);
– izdelovalce tratnih robov, gonilnike mlatilcev, kosilce s srpom na drogu ali poljedelske kosilce.
Ta evropski standard se ne uporablja za prezračevalnike/rahljalnike, izdelane pred izdajo tega dokumenta.
Ta evropski standard opisuje vsa večja tveganja, ki jih predstavljajo ročno upravljani rahljalniki in prezračevalniki travne ruše, kadar se uporabljajo v skladu z njihovim namenom in pod pogoji razumno predvidene nepravilne uporabe.
OPOMBA 2: Stroji z motorjem z zgorevanjem so obravnavani v standardu EN 13684.

Foreword
This document (EN 50636-2-92:2014) has been prepared by CLC/TC 116 "Safety of motor-operated
electric tools".
The following dates are fixed:
(dop) 2014-12-20
• latest date by which this document has to be
implemented
at national level by publication of an identical
national standard or by endorsement
• latest date by which the national standards conflicting (dow) 2016-09-02
with this document have to be withdrawn
This document supersedes EN 60335-2-92:2005.
EN 60335-2-92:2014 includes the following significant technical changes:
– rewording of some clauses;
– alignment to the European Machinery Directive 2006/42/EC;
– alignment to EN 60335-1:2012.
This document 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 document supplements or modifies the corresponding clauses in Part 1, so as to convert that
publication into the European Standard “Particular requirements for pedestrian-controlled walk-
behind mains operated scarifiers and aerators”.
Where a particular subclause of Part 1 is not mentioned in this 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 Stan
