IEC 60335-2-92:2000

Safety of household and similar appliances - 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.

SAFETY OF HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –

Part 2-92: Particular requirements for pedestrian-controlled

mains-operated lawn scarifiers and aerators

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC subcommittee 61F:
Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of
household and similar electrical appliances.
It forms the first edition of IEC 60335-2-92.
The text of this standard is based on the following documents:

FDIS Report on voting
61F/320/FDIS 61F/344/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This part 2-92 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the third edition (1991) of that standard.
This part 2-92 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert it into the IEC standard: Safety requirements for pedestrian-controlled mains-operated
lawn scarifiers and aerators.
60335-2-92  IEC:2000(E) – 5 –

Where a particular subclause of part 1 is not mentioned in this part 2-92, that subclause

applies as far as is reasonable. Where this standard states "addition", "modification" or

"replacement", the relevant text in part 1 is to be adopted accordingly.

NOTE 1 The following print type are used:

– requirements: in roman type;

– test specifications: in italic type;

– notes: in small roman type;
Words in bold in the text are defined in clause 2. When a definition of part 1 concerns an adjective, the adjective
and the associated noun are also in bold.

NOTE 2 Subclauses which are additional to those in part 1 are numbered starting from 101.
A bilingual version of this publication may be issued at a later date.
