Clause Requirement – Test Result Verdict
Clearance between surfaces of PTC heating
elements may be reduced to 1 mm
No PTC heating elements. N/A
Lacquered conductors of windings assumed to be
bare conductors, but the clearances specified in
table 16 are reduced by 0,5 mm for rated impulse
voltages of at least 1500 V
N/A
29.1.5
Appliances having higher working voltage than rated
voltage, the voltage used for determining clearances
from table 16 is the sum of the rated impulse voltage
and the difference between the peak value of the
working voltage and the peak value of the rated
voltage
N/A
If the secondary winding of a step-down transformer
is earthed, or if there is an earthed screen between
the primary and secondary windings, clearances of
basic insulation on the secondary side not less than
those specified in table 16, but using the next lower
step for rated impulse voltage
N/A
Circuits supplied with a voltage lower than rated
voltage, clearances of functional insulation based on
the working voltage used as the rated voltage in
table 15
P
29.2
Creepage distances not less than those appropriate
for the working voltage, taking into account the
material group and the pollution degree
P
Pollution degree 2 applies, unless
Pollution degree 2. P
precautions taken to protect the insulation;
pollution degree 1
N/A
insulation subjected to conductive pollution;
pollution degree 3
N/A
Compliance is checked by inspection and
measurements as specified
(See appended table)
P
Insulation located in airflow, pollution degree 3
unless (IEC 60335-2-40)
Protected from airflow in
internal compartments.
N/A
insulation enclosed or located so that unlikely to be
exposed to pollution due to normal use
(IEC 60335-2-40)
N/A
29.2.1
Creepage distances of basic insulation not less than
specified in table 17
P
For pollution degree 1, creepage distance not less
than the minimum specified for the clearance in
table 16, if the clearance has been checked
according to the test of clause 14
Pollution degree 2. N/A
29.2.2
Creepage distances of supplementary insulation at
least as specified for basic insulation in table 17
