separated from live parts by at least double or reinforced insulation. There shall be no
connection between the output circuit and the body or the protective earthing circuit, if any.
Moreover, the construction shall be such that there is no possibility of any connection
between these circuits, either directly or indirectly, through other conductive parts, except by
deliberate action (see 10.4).
SELV output circuits shall be electrically separated from earth by at least basic insulation.
The expression “circuits” also covers windings of internal transformers (HF and others) of the
controlgear.
In controlgears providing ELV conductive parts are regarded as live parts and shall be
insulated accordingly.
Compliance is checked by inspection, relevant insulation tests and measurements. See also
Annex L.
61347-1 Amend.2 © IEC:2012 – 9 –
10.4 Controlgears providing SELV may have accessible conductive parts in the SELV circuit;
if: the rated output voltage under load does not exceed 25 V r.m.s. or 60 V d.c. ripple free d.c.
where the voltage exceeds 25 V r.m.s. or 60 V ripple free d.c., the touch current does not
exceed:
– for a.c.: 0,7 mA (peak);
– for d.c.: 2,0 mA;
– the no-load output does not exceed 35 V peak or 60 V ripple free d.c.
NOTE The limits given are based on IEC 60364-4-41.
Compliance is checked by measuring the output voltage when steady conditions are
established, the controlgear being connected to rated supply voltage and rated frequency. For
the test under load the controlgear is loaded with a resistance which would give rated output
(current or wattage respectively) at rated output voltage. For controlgears with more than one
supply voltage, the requirements are applicable for each of the rated supply voltages.
The touch current is checked by measurement in accordance with Annex G from IEC 60598-1.
For controlgears providing SELV with rated output voltages or currents exceeding the values
given above at least one of the conductive parts in the SELV circuit shall be insulated by
insulation capable of withstanding a test voltage of 500 V r.m.s. for 1 min.
Accessible conductive parts separated by double or reinforced insulation, e.g. live parts and
the body or primary and secondary circuits, may be bridged (conductive bridged) by resistors
or Y2 capacitors provided they consists of at least two separate components of the same
rated value (resistance or capacitance) and are rated for the total working voltage and whose
impedance is unlikely to change significantly during the individual lifetime of the controlgear.
In addition, accessible conductive parts separated by double or reinforced insulation from live
parts, as above, may be bridged by a single Y1 capacitor.
Y1 or Y2 capacitors shall comply with relevant requirements of IEC 60384-14 and if resistors
are used they shall comply with the requirements of test (a) in 14.1 of IEC 60065:2001.

11 Moisture resistance and insulation
Replace, after the third paragraph after the note, the rest of the text of Clause 11 by the
following:
Insulation resistance shall be not less than 2 MΩ for basic insulation and 4 MΩ for double or
reinforced insulation between live parts and the body. For insulation between primary and
secondary circuits, in controlgear providing SELV, other values apply (see Annex L).
Insulation shall be adequate
a) between live parts and outer metal parts, including fixing screws and metal foil in contact
with outer insulating parts;
b) between live parts and control terminals, where relevant.
In the case of lamp controlgear having an internal connection or component between one or
more output terminals and the earth terminal, such a connection shall be removed during
this test.
For the test the input and output terminals shall be bonded together. Controlgear, having
insulation cover or envelope is wrapped with metal foil.

– 10 – 61347-1 Amend.2 © IEC:2012
12 Electric strength
Replace the existing Table 1 by the following new Table 1:
Table 1 – Electric strength test voltage
Test voltage
Working voltage U
V
Basic insulation for voltages of SELV 500
Up to and including 50 V 500
Basic insulation 2 U + 1 000
Above 50 V up to and including 1 000 V Supplementary insulation 2 U + 1 000
Double or reinforced insulation 4 U + 2 000
Where both reinforced insulation and double insulation are used, care shall be taken that the voltage applied to
the reinforced insulation does not overstress the basic insulation or the supplementary insulation.
When testing the controlgear the input should be tested with a test voltage which corresponds with the supply
voltage and the output related part should be tested with a test voltage which corresponds with U .
out
Add the following sentence after Table 1:
For solid or thin sheet insulation used for double or reinforced insulation Annex N applies.

Annex A – Test to establish whether a conductive part is a live part which may
cause an electric shock
Replace the existing text of Annex A by the following:

A.1 In order to determine whether a conductive part is a live part which may cause an
electric shock, the lamp controlgear is operated at rated voltage and nominal supply
frequency. A conductive part is not a live part if the requirements of Clause A.2 or A.3 are
met.
For the test according to Clause A.2 and A.3,
– one pole of the supply of the DUT shall be at earth potential,
– the measurements shall be carried out between the part concerned and any accessible
conductive part and/or earth.
NOTE The purpose of this annex is to establish if a conductive part may cause electric shock if touched. It does
not give response about the kind and level of insulation used.
A.2 The voltage shall be measured by using a measuring circuit consisting of a non-
inductive resistance of 50 kΩ.
– the voltage shall not exceed 35 V a.c. peak or 60 V ripple free d.c.
A.3 Where the voltage exceeds 35 V a.c. peak or 60 V ripple free d.c. or a protective
impedance device is used the touch-current shall not exceed:
– for a.c.: 0,7 mA (peak);
– for d.c.: 2,0 mA.
