5 General notes on tests
The requirements of Clause 5 of IEC 61347-1 apply, with the following additional requirement:
5.8 Number of specimens
The following number of specimens shall be submitted for testing:
— one unit for the tests of Clauses 6 to 12 and 15 to 20;
— one unit for the tests of Clause 14 (additional units or components, where necessary, may be required in consultation with the manufacturer).
Unless otherwise declared by the manufacturer, the tests are carried out with the length of the output wire or cable either 20 cm or 200 cm, choosing the most unfavourable condition. It is possible to use two twisted wires or cable HO3VV-. The cross section of the conductors shall be chosen according to the rated wattage and the current density shall not exceed 5 A/mm2 in normal use.
6 Classification
Convertors are classified according to the method of installation given in Clause 6 of IEC 61347-1 and according to:
— Protection against electric shock
• auto wound (autotransformer) convertors,
• separating convertors,
• SELV convertors.
7 Marking
7.1 Mandatory marking
Convertors, other than integral convertors, shall be clearly and durably marked, in accordance with the requirements of 7.2 of IEC 61347-1, with the following mandatory markings:
— items a), b), c), d), e), f), k), I), rn), s) and t) of 7.1 of IEC 61347-1, together with
— rated output voltage.
7.2 Information to be provided if applicable
In addition to the above mandatory markings, the following information, if applicable, shall be
given either on the convertor, or be made available in the manufacturer’s catalogue or similar:
— items h), i), j) and s) of 7.1 of IEC 61347-1 together with
— mention whether the convertor has mains-connected windings,
— a declaration of the allowed length of the output wire or cable, if it is not between 20 cm and 200 cm.
8 Protection against accidental contact with live parts
