FOREWORD
This amendment has been prepared by subcommittee 61B: Safety of microwave ovens, of IEC
technical committee 61: Safety of household and similar electrical appliances.
The text of this standard is based on the following documents:
FDIS Report on voting
61B/416/FDIS 61B/424/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.
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• withdrawn,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.

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.
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.

– 4 – 60335-2-90 Amend. 1 © IEC:2010
The door system, including hinges, microwave seals and other associated parts, shall be
constructed to withstand wear that may be expected in normal use.
Compliance is checked by the following test.
The door system is subjected to 100 000 cycles of operation with the appliance supplied at
rated voltage and containing an appropriate microwave-absorbing load. It is then subjected
to 100 000 cycles of operation without microwave generation.
The door is opened and closed as in normal use. It is opened from the closed position to a
position approximately 10° before fully open. The rate of operation is 6 cycles per minute.
With the agreement of the manufacturer the rate of operation without microwave generation
can be increased to 12 cycles per minute.
After the test, the microwave leakage shall not exceed the limit specified in Clause 32 and the
door system shall still function.
NOTE 101 Controls may be rendered inoperative in order to carry out the test.
NOTE 102 Components, the deterioration of which does not impair compliance with this standard, may be
replaced in order to complete the test.
NOTE 103 Bricks or additional water of maximum 1 000 g may be added if necessary to avoid stopping of the test
due to overheating.
22 Construction
Add the following new subclause:
22.119 If electronic circuits are used to provide protection against microwave leakage they
shall be designed so that a fault condition will not affect protection against microwave
leakage.
Compliance is checked by applying the tests in Clause 19 in conjunction with the
requirements and test specifications in 22.105, 22.106, 22.107 and 22.108.
Annexes
Add the following new Annex EE:
