[ISO817] classification.
3.122
refrigerating system
combination of interconnected refrigerant containing parts constituting one closed refrigerant
circuit in which refrigerant is circulated for the purpose of extracting heat at the low
temperature side to reject heat at the high temperature side by changing the state of the
refrigerant
3.123
maximum allowable pressure
a limit to the refrigerating system operating pressure, generally the maximum pressure for
which the equipment is designed, as specified by the manufacturer
NOTE Maximum allowable pressure constitutes a limit to the operating pressure whether the equipment is
working or not, see Clause 21.

a means to access the refrigerant in a refrigerating system for the purpose of charging or
servicing the system, typically a valve, tube extension or entry location
5 General conditions for the tests
Add the following subclause:
5.2 Addition:
The testing of Clause 21 may be carried out on separate samples. The testing of Clauses 11,
19 and 21 shall require that pressure measurements be made at various points in the
refrigerating system
At least one additional specially prepared sample is required for the tests of Annex FF (Leak
simulation tests), if that test option is selected.
The temperatures on the refrigerant piping should be measured during the test of Clause 11.
NOTE Due to the potentially hazardous nature of the tests of Clause 21 and Annexes EE and FF, special
precautions need to be taken when carrying out the tests.
5.102 Motor compressors that are tested and comply with IEC 60335-2-34 need not be

60335-2-40 Amend. 1 IEC:2005(E) – 5 –
7 Marking and instructions
7.1 Modification:
Add the following paragraphs to the existing addition:
The flame symbol and the instruction manual symbol of 7.6 shall be visible when a flammable
refrigerant is employed and the following conditions exist:
– accessing parts expected to be subjected to maintenance or repair;
– observing the appliance under sale or installed conditions;
– observing the appliance packaging, if the appliance is charged with refrigerant.
If a flammable refrigerant is used, the symbols for “read operator’s manual”, “operator’s
manual; operating instructions” and “service indicator; read technical manual” (symbols 0790,
1641 and 1659 of ISO 7000) shall be placed on the appliance in a location visible to the
persons required to know the information. The perpendicular height shall be at least 10 mm.
An additional warning symbol (flame symbol: B.3.2 of ISO 3864) shall be placed on the
nameplate of the unit near the declaration of the refrigerant type and charge information. The
perpendicular height shall be at least 10 mm, and the symbol need not be in colour.
NOTE 101 When installed, the marking should be visible after removing a detachable part.
The following warning shall also be applied to the appliance when a flammable refrigerant is
employed.
WARNING
Appliance shall be installed, operated and stored in a room with a floor area larger than
‘X’ m (only applies to appliances that are not fixed appliances).
For appliances, which are not fixed appliances, the minimum room size X shall be specified
on the appliance. The X in the marking shall be determined in m by the procedure described
in paragraph 2 of Annex GG for unventilated areas and the X in the marking shall be 4 if the
refrigerant charge of the appliance is less than m (see Annex GG, paragraph 1.1).
The maximum allowable pressure for the low-pressure side and the high-pressure side shall
be marked on the product.
NOTE 102 For the refrigerating system; if the maximum allowable pressure of the low-pressure side and the
high-pressure side is the same, a single indication is permitted.
If not already visible when accessing a service port and if a service port is provided, the
service port shall be marked to identify the type of refrigerant. If the refrigerant is flammable,
symbol B.3.2 of ISO 3864, shall be included, without specifying the colour.
Add the following subclause:
7.6 Addition:
When a flammable refrigerant is employed, a warning symbol B.3.2 of ISO 3864, including
colour and format, shall be permanently placed on the appliance. The perpendicular height of
the triangle containing the "Caution, risk of fire" symbol shall be at least 30 mm.
When a flammable refrigerant is employed, a symbol requiring reference to the manual [0790 of
ISO 7000], including colour and format, shall be permanently placed on the appliance.
– 6 – 60335-2-40 Amend. 1 IEC:2005(E)
7.12 Addition:
For appliances using flammable refrigerants, an installation, service and operation manual,
either separate or combined manuals, shall be provided and include the information given in
Annex DD.
19 Abnormal operation
Add the following subclause after subclause 19.10
19.10.1 The test of 19.10 is repeated on class 01 appliances and class 1 appliances
incorporating tubular sheathed or embedded heating elements. However, controls are not
short-circuited but one end of the element is connected to the sheath of the heating element.
The test is repeated with the polarity of the supply to the appliance reversed and with the
other end of the element connected to the sheath.
The test is not carried out on appliances intended to be permanently connected to fixed wiring
and on appliances where all-pole disconnection occurs during the test of 19.10.
19.14 Amend the opening of the first sentence to read:
"During the tests of 19.2 to 19.10.1 and 19.11."
21 Mechanical strength
Add the following paragraph:
Safety requirements specified in Annex EE shall apply. The pressure test in Annex EE applies
to parts other than pressure vessels.
22 Construction
Add the following new subclauses:
22.112 The construction of the refrigerating system shall comply with the requirements of
Section 3 of ISO 5149.
22.113 When a flammable refrigerant is used, refrigerant tubing shall be protected or
enclosed to avoid mechanical damage. The tubing shall be protected to the extent that it will
not be handled or used for carrying during moving of the product. Tubing located within the
confines of the cabinet is considered to be protected from mechanical damage.
Compliance is checked by inspection.
22.114 When a flammable refrigerant is used, low temperature solder alloys, such as
lead/tin alloys, are not acceptable for pipe connections.
22.115 The total refrigerant mass (M) of all refrigerating systems within the appliance
employing flammable refrigerants, shall not exceed m as defined in Annex GG.
22.116 Appliances using flammable refrigerants shall be constructed so that any leaked
refrigerant will not flow or stagnate so as to cause a fire or explosion hazard in areas within
the appliance where electrical components, which could be a source of ignition and which
could function under normal conditions or in the event of a leak, are fitted.
60335-2-40 Amend. 1 IEC:2005(E) – 7 –
Separate components, such as thermostats, which are charged with less than 0,5 g of a
flammable gas are not considered to cause a fire or explosion hazard in the event of leakage
of the gas within the component itself.
All electrical components that could be a source of ignition and which could function under
normal conditions or in the event of a leak, shall comply with one of the following.
– IEC 60079-15:2001, Clauses 9 to 26, for group IIA gases or the refrigerant used or an
applicable standard that makes electrical components suitable for use in Zone 2, 1 or 0 as
defined in IEC 60079-14.
– Not be located in an area where a potentially flammable gas mixture will accumulate as
demonstrated by the test of Annex FF
– Be located in an enclosure. The enclosure containing the electrical components shall
comply with IEC 60079-15:2001 for enclosures suitable for use with group IIA gases or the
refrigerant used.
NOTE The test current for a switching component is the rated current of the component or the actual load to be
switched, whichever is greater.
22.117 Temperatures on surfaces that may be exposed to leakage of flammable
refrigerants shall not exceed the auto-ignition temperature of the refrigerant reduced by
100 K; some typical values are given in Annex BB.
Compliance is checked by measuring the appropriate surface temperatures during the tests of
Clauses 11 and 19, except those which during the tests of Clause 19 are terminated in a non-
self-resetting way.
22.118 When a flammable refrigerant is used, all appliances shall be charged with
refrigerant at the manufacturing loca
