IEC 60884-2-7-2013 pdf download.Plugs and socket-outlets for household and similar purposes – Part 2-7: Particular requirements for cord extension sets.
IEC 60884-2-7 does not apply to cord extension sets with means for reeling.
This standard also applies to cord extension sets which are intended to be used in a cable reel, and which therefore become cable reels with a detachable flexible cable. For the combination of the cord extension set, the reel requirements and tests of IEC 61242 have to be fulfilled in addition.
Cord extension sets suitable for use at ambient temperatures not normally exceeding +40 C, but their average over a period of 24 h does not exceed +35 °C, with a lower limit of the ambient air temperature of —5 °C.
NOTE 3 In the following country, cord extension sets comprising a socket outlet for class II equipment are not permitted; socket-outlets in cord extension sets shall always be Class 1 as delined in EN 61140: DK, UK.

3 Definitions
This clause of Part 1 is applicable except as follows.
Replacement of NOTE 3:
4 General requIrements
This clause of Part 1 is applicable except as follows:
Addition of the (0110 wing paragraph at the end of the clause:
Components such as plugs, socket-outlets (including multiple socket-outlets) and flexible cables of the cord extension sets shall be fully compliant with, and have been verified against, the relevant product standards for those components.
5 General remarks on tests
Replacement:
5.1 Tests shall be made to prove compliance with the requirements laid down in this standard.
No extra requirements for components (plugs, socket outlets and flexible cables) have to be applied and the relevant tests shall not be repeated.
Tests are made as follows:
— type tests shall be made on representative specimens of each assembly:
— routine tests shall be made on each assembly manufactured according to this standard.
Subclauses 5.2 to 5.5 are applicable to type tests and Subclause 5.6 to routine tests.
NOTE In the following country, the following tests are carried out on samples of the cord extension set In accordance with the sampling requirements specified in Clauses 5, 17, 18, 19, 20, 21, 22. 23, 24. 25, 26, 28, 29 and 30: ZA.
5.2 The specimens are tested as delivered and under normal conditions of use.
5.3 Unless otherwise specified, the tests are carried out in the order of the clauses, at an ambient temperature between 15 V and 35 V.
In case of doubt, the tests are made at an ambient temperature of (20 ± 5) CC.
5.4 Three specimens are subjected to all the relevant tests.
5.5 The specimens are submitted to all the relevant tests and the requirements are satisfied if all the tests are met.
If one specimen does not satisfy a test due to a manufacturing cord extension sets process fault, that test and any preceding one which may have influenced the results of the test shall be repeated, and also the tests which follow shall be made in the required sequence on another full set of specimens, all of which shall comply with the requirements.
NOTE The applicant may submit, together with a number ol specimens specilied in Subclause 5.4, the additional set of specimens which may be required. should one specimen fail. The testing station will then, without further request, test the additional specimens and will only reject them if a further failure occurs, If the additional set of specimens is not submitted at the same time, the failure of one specimen will entail rejection.
5.6 Routine tests are specified in Annex A.
6 Ratings
This clause of Part 1 is applicable except as follows.
Replacement:
6.2 The rated current of the cord extension set shall be the lowest value from
a) the rated current of the plug; or
b) the arithmetic sum of the highest rated currents of all plugs which can be inserted into the cord extension set; or
C) the rated current of the overcurrent protective overcurrent device having the smallest rated current.
The rated voltage of the cord extension set is that of the plug.
Compliance is checked by inspection of the marking.
7 Classification
This clause of Part 1 is not applicable except for 7.1.1, 7.1.2. 7.1 .3 and 7.1.4.
