For construction according to 26.2.4.1, test B the voltage is multiplied by the factor 1,25. For
the construction according to 26.2.4.2 the voltage is multiplied by the factor 1,35.
Add, after the existing subclause 18.101, the following new subclause and new figure:
18.102 A partial discharge test according to IEC 60664-1, (test description see below) shall
be performed, if FIW wires are used and if the recurring peak working voltage U across the
t
insulation is greater than 750 V. The relevant recurring peak voltage is the maximum
measured voltage between the input and the output circuit of the SMPS, if the secondary side
is earthed. The measuring shall be done at 1,0 of the maximum rated input voltage.
A partial discharge test shall be done at the transformer for the SMPS with the measured
recurring peak voltage U , greater than 750 V peak.
t
U is the maximum peak working voltage;
t
is 5 s;

19 Construction
Add, at the end of the existing text of this clause, the following new text:
19.12.3 Replacement:
Insulated winding wires, in an insulation system providing basic, supplementary or
reinforced insulation, shall meet the following requirements.
Wire that has multi-layer extruded or spirally wrapped insulation (where only the finished wire
can be tested) and passes the tests of Annex K.
The minimum number of constructional layers applied to the conductor shall be as follows:
– BASIC INSULATION: two wrapped layers or one extruded layer;
– SUPPLEMENTARY INSULATION: two layers, wrapped or extruded;
– REINFORCED INSULATION: three layers wrapped or extruded.
For spirally wrapped insulation where the CREEPAGE DISTANCES between layers, as wrapped,
are less than those given in Clause 26. for pollution degree 1, the path between layers shall
be sealed as for a cemented joint in 26.2.3, Test A and the test voltages of the TYPE TESTS in
Clause K.2 are increased to 1,35 times their normal values.
NOTE 1 One layer of material wound with more than 50 % overlap is considered to constitute two layers.

61558-2-16 Amend. 1 © IEC:2013 – 5 –
The finished component shall pass ROUTINE TEST for electric strength using the appropriate
value of test voltages in 18.3.
Compliance is checked by inspection and measurement and, if applicable, as specified in
Annex K.
a) Where the insulation on the winding wire is used to provide basic- or supplementary
insulation in a wound part:
– the insulated wire (for example polyimide or insulation of equivalent quality) shall
comply with Annex K;
