Clause Requirement – Test Result Verdict
Terminals used for the connection of external
equipotential bonding conductors allow connection of
conductors of 2,5 to 6 mm², and
N/A
do not provide earthing continuity between different
parts of the appliance
N/A
Conductors cannot be loosened without the aid of a
tool
P
27.3
For detachable parts that are plugged into another
part of the appliance, and having an earth
connection, the earth connection made before and
separated after current-carrying connections when
removing the part (IEC 60335-1/A1)
Not such construction. N/A
For appliances with supply cord, current-carrying
conductors become taut before earthing conductor, if
the cord slips out of the cord anchorage
P
27.4
No risk of corrosion resulting from contact between
metal of earthing terminal and other metal
All parts have adequate
protection against corrosion.
P
Adequate resistance to corrosion of coated or
uncoated parts providing earthing continuity, other
than parts of a metal frame or enclosure
Adequately protected against
corrosion.
P
Parts of steel providing earthing continuity provided
at the essential areas with an electroplated coating,
thickness at least 5 µm
P
Adequate protection against rusting of parts of
coated or uncoated steel, only intended to provide or
transmit contact pressure
P
In case of aluminium alloys precautions taken to
avoid risk of corrosion
No aluminium alloy. N/A
27.5
Low resistance of connection between earthing
terminal and earthed metal parts
P
This requirement does not apply to connections
providing earthing continuity in the protective
extra-low voltage circuit, provided that clearances of
basic insulation are based on the rated voltage of the
appliance
N/A
Resistance not exceeding 0,1 Ω at the specified
low-resistance test
Applied current: 25A
Measured resistance; 0.035 Ω
(PE of indoor unit to the
accessible metal part of
outdoor unit)
It shall be checked with an
appliance connecting the
indoor unit with the outdoor
unit again, if the value of 1,5
times rated current is greater
than 25A.
