FOREWORD
This amendment has been prepared by IEC subcommittee 61E: Safety of electrical
commercial catering equipment, 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
61E/617/FDIS 61E/620/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 maintenance result 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• withdrawn,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.

Title
Replace the title by the following:
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-49: Particular requirements for commercial electric appliances
for keeping food and crockery warm

INTRODUCTION
Replace the second sentence of the second paragraph by the following:
It also covers abnormal situations that can be expected in practice and takes into account the
way in which electromagnetic phenomena can affect the safe operation of appliances.

60335-2-49 Amend. 1 © IEC:2008 – 3 –
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.
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.
1 Scope
In the second paragraph, replace “hot cupboards” by “appliances for keeping food and
crockery warm”.
Replace the third paragraph by the following:
Examples of appliances that are within the scope of this standard are:
– hot cupboards, with or without heated tops;
– heated tops;
– heated display cases;
– heated crockery dispensers;
– heated tables;
– radiant heaters.
3 Definitions
3.1.9 Add the following:

crockery placed on induction trays. All tray supports are loaded, but partial up to full load

All controls are set to maximum, and the induction crockery is half-filled with initially cold
water. Covers (cloches) are in their position.
The appliances consist of several units, which can form up to three separated modules; they
are connected together during operation. These units are the heating module with the
induction heating source, the rack with the coil carriers and the enclosure with the
supports for the induction trays including the induction crockery.
Add the following new definitions:

The operation of appliances incorporating induction heating sources requires an increased
instruction of the personnel. In addition, the instructions shall state that any repairs shall be
carried out only by persons trained or recommended by the manufacturer.
