IEC 60884-2-7 pdf download.Plugs and socket-outlets for household and similar purposes – Part 2-7: Particular requirements for cord extension sets
1 Scope
Replacement: This Part of IEC 60884 applies to cord extension sets, rewirable and non rewirable, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 1 6 A, intended for household and similar purposes, either indoors or outdoors. NOTE 1 In the following countries, cord extension sets only for equipment of class II are not allowed: DE, UK and CZ. NOTE 2 In the following country, rewirable cord extension sets are not allowed: ZA. This standard 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 61 242 have to be fulfilled in addition. Cord extension sets should be suitable for use at ambient temperatures not normally exceeding +40 ºC, 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.
3 Definitions
This clause of Part 1 is applicable except as follows. Replacement of NOTE 3: NOTE 3 The term “portable accessory” covers plugs, portable socket-outlets and cord extension sets. Examples of the use of accessories are shown in Figure 1 a) of IEC 60884-1 .3.1 2 cord extension set Addition: NOTE 1 01 The term “plug” covers plugs and fused plugs. The term “socket outlet” covers also socket outlets with incorporated components such as switches and fuses etc. which are required to comply with the relevant IEC standard as far as it applies. 3.1 2.101 rewirable cord extension set cord extension set so constructed that any of the accessories or the flexible cable can be replaced with the aid of a general purpose tool 3.1 2.102 non-rewirable cord extension set cord extension set so constructed that it forms a complete unit with the flexible cable, the plug and the socket-outlet after connection and assembly by the manufacturer, the disassembly of which makes it permanently unfit for any further use
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. 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 °C and 35 °C. In case of doubt, the tests are made at an ambient temperature of (20 ± 5) °C. 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 of specimens specified 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.
