FOREWORD
This amendment has been prepared by sub-committee 61C: Safety of refrigeration appliances for
household and commercial use, of IEC technical committee 61: Safety of household and similar
electrical appliances.
This bilingual version (2019-09) corresponds to the monolingual English version, published in
2015-05.
The text of this amendment is based on the following documents:
FDIS Report on voting
61C/598/FDIS 61C/604/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 French version of this standard has not been voted upon.
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• withdrawn,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.
___________
1 Scope
In Note 104 replace “ISO 5149” by “ISO 5149-1”.
2 Normative references
Delete references IEC 60079-4A and IEC 60079-20 from the existing list.
Add the following new reference:
IEC 60079-20-1, Explosive atmospheres – Part 20-1: Material characteristics for gas and
vapour classification – Test methods and data
Replace the reference to ISO 817 by the following new reference:
ISO 817, Refrigerants – Designation and safety classification

© IEC 2015
Replace the reference to IS0 5149 by the following new reference:
ISO 5149-1, Refrigerating systems and heat pumps – Safety and environmental requirements
– Part 1: Definitions, classification and selection criteria
3 Terms and definitions
3.101 In the term definition delete “enclosed”.
3.105 In the term definition replace “ISO 5149” by “ISO 5149-1”.
3.109 Add the following Note to entry.
Note 1 to entry: The design pressure assigned should take into account pressures that could be expected during
transportation of the transcritical refrigeration system.
3.111 Add “during abnormal operation” to the end of the term definition.
5 General conditions for the tests
5.2 Add the following paragraph to the addition.
Unless the motor-compressor complies with IEC 60335-2-34, at least one additional specially
prepared sample is required for the tests of 22.103.
5.10 Delete the second paragraph of the addition.
In the existing third paragraph of the addition replace “Other appliances” by “Appliances,
other than built-in appliances,”
Add the following as a new third paragraph to the addition.
For appliances incorporating remote refrigerant units or remote motor-compressors, the
refrigerant line between the refrigerant unit or motor-compressor and the refrigerated
display and storage cabinet shall have a length of 5 m to 7,5 m. The refrigerant line shall be
installed with thermal insulation applied in accordance with the instructions. If the appliance
employs a transcritical refrigeration system, a pressure relief device shall be installed on
the high pressure side between the motor-compressor and the gas cooler unless it is pre-
fitted to the motor-compressor.
7 Markings and instructions
7.1 In the paragraph after Note 101, replace “the symbol “Caution: risk of fire” with “symbol
ISO 7010 W021”.
7.6 In the note, replace “the symbol “Caution: risk of fire” with “symbol ISO 7010 W021”.
7.12 Add the following:
If symbol ISO 7010 W021 is used, its meaning shall be explained.

7.14 In the first paragraph, replace “the symbol “Caution: risk of fire” with “symbol ISO 7010
W021”.
7.15 In the third paragraph, replace “symbol “Caution: risk of fire” with “symbol ISO 7010
W021”.
22 Construction
22.103 Add the following sentence to the end of the second paragraph of the requirement
“This requirement is not applicable where the pressure is controlled automatically by shutting
down the motor-compressor.”
In the second paragraph of the test specification replace “raised gradually” by “gradually
increased hydraulically” and change the style of the first dashed item to italic type.
22.104 Replace the text by the following:
Accessible glass panels with an area having any two orthogonal dimensions exceeding
75 mm shall be made from
• glass that breaks into small pieces when it fractures; or
• glass that is not released or dropped from its normal position when broken.
a) For glass that breaks into small pieces when it fractures, compliance is checked by the
following test which is performed on two samples.
Frames or other parts attached to the glass panel to be tested are removed and the glass
is placed on a rigid horizontal flat surface.
NOTE 1 The edges of the sample to be tested are contained within a frame of adhesive tape in such a
manner that the broken pieces remain in place after breakage but without hindering expansion of the sample.
The sample under test is broken by means of a test punch having a head with a mass of
75 g ± 5 g and a conical tungsten carbide tip with an angle of 60°± 2°. The punch shall be
positioned approximately 13 mm in from the longest edge of the glass at the midpoint of
that edge. The punch is then hit by a hammer so that the glass breaks.
A transparent mask of 50 mm × 50 mm is placed on the fractured glass except within a
peripheral margin of 25 mm from the edge of the sample.
The assessment shall be undertaken on at least two areas of the sample, and the areas
chosen shall contain the largest particles.
The number of crack free particles within the mask are counted and for each assessment
shall not be less than 40. The particle count shall be made within 5 minutes of the
fracture. Each particle wholly contained within the area of the mask shall be counted as
one particle and each particle that is partially within the mask shall be counted as a half
particle.
NOTE 2 In the case of curved glass, plane pieces of the same material can be used for the test.
b) For glass that is not released or dropped from its normal position when broken,
compliance is checked by braking the glass when mounted in its normal position in the
appliance by means of a test punch having a head with a mass of 75 g ± 5 g and a conical
tungsten carbide tip with an angle of 60°± 2°. The punch shall be positioned approximately
13 mm in from the longest edge of the glass at the midpoint of that edge. The punch is
then hit by a hammer so that the glass breaks.
At the conclusion of this test, the glass shall not be broken or cracked in such a way that
pieces are released or dropped from their normal position. Glass that is released within
the immediate vicinity of the punch tip as a result of the punch impacting the sample under
test is ignored.

22.109 In the requirement, replace “ignition” by “auto-ignition”.
