Clause Requirement – Test Result Verdict
All electrical components that could be a source of ignition and which could function
under normal conditions or in the event of a leak, comply with one of the following
(IEC 60335-2-40/A1):
—
- IEC 60079-15:2001, Cl. 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
(IEC 60335-2-40/A1)
Intended for the use of a non-
flammable refrigerant.
N/A
- Not be located in an area where a potentially
flammable gas mixture will accumulate as
demonstrated by the test of annex FF
(IEC 60335-2-40/A1)
N/A
- Be located in an enclosure. The enclosure
containing the electrical components comply with
IEC 60079-15:2001 for enclosures suitable for use
with group IIA gases or the refrigerant used
(IEC 60335-2-40/A1)
N/A
22.117
Temperatures on surfaces that exposed to leakage
of flammable refrigerants not exceed auto-ignition
temperature of refrigerant reduced by 100 K; some
typical values given in annex BB
(IEC 60335-2-40/A1)
Intended for the use of a non-
flammable refrigerant.
N/A
22.118
Flammable refrigerant used, all appliances charged
with refrigerant at manufacturing location or charged
on site as recommended by manufacturer
(IEC 60335-2-40/A1)
Intended for the use of a non-
flammable refrigerant.
N/A
Part of appliance that charged on site, which requires brazing or welding in installation
not shipped with flammable refrigerant charge. Joints made in installation between
parts of refrigerating system, with at least one part charged, made in accordance with
following (IEC 60335-2-40/A1):
—
- A brazed, welded, or mechanical connection shall
be made before opening the valves to permit
refrigerant to flow between the refrigerating system
parts. A vacuum valve shall be provided to
evacuate the interconnecting pipe and/or any
uncharged refrigerating system part
(IEC 60335-2-40/A1)
N/A
- Reusable mechanical connectors and flared joints
are not allowed indoors (IEC 60335-2-40/A1)
N/A
- Refrigerant tubing shall be protected or enclosed to
avoid damage (IEC 60335-2-40/A1)
N/A
Flexible refrigerant connectors (such as connecting
lines between the indoor and outdoor unit) that may
be displaced during normal operations shall be
protected against mechanical damage
(IEC 60335-2-40/A1)
N/A
