Add, after the existing Table 8a, the following new instruction:
Replacement of the text in footnote a of Table 8a:

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.

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

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.
U is the maximum peak working voltage;
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.

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;

– the insulation of one insulated winding wire shall consist of at least two layers for

supplementary insulation;

– the insulation of one insulated winding wire shall consist of at least one layer for

basic insulation;

– an insulation for mechanical separation which fulfil the electric strength test for basic

insulation shall
