FOREWORD


This amendment has been prepared by subcommittee 61H: Safety of electrically-operated

farm appliances, of IEC technical committee 61: Safety of household and similar electrical

appliances.


The text of this amendment is based on the following documents:


FDIS Report on voting

61H/287/FDIS 61H/289/RVD


Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
The committee has decided that the contents of this amendment and the base publication will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.

_____________
CONTENTS
Replace the title of Clause 3 but not the clause number, by the following:

Terms and definitions
Replace the title of Clause 28 but not the clause number, by the following:
Screws and connections

INTRODUCTION
Replace the fifth paragraph by the following:
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.

---------------------- Page: 4 ----------------------
60335-2-76 Amend. 2 © IEC:2013 – 3 –


NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is

not necessary to specify particular requirements for the appliance in question over and above the general
requirements.


This standard is a product family standard dealing with the safety of appliances and takes

precedence over horizontal and generic standards covering the same subject.


NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into

consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as

ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
