31、is standard specifies general safety requirements for mini-couplers with a rated current of 16 A and a rated voltage of 250 V a.c. single phase, applied for the interconnection of mains supplied equipment in road vehicles, e.g. to supply electrical heaters, battery chargers and cab heaters. This sta
32、ndard may also be used for mini-couplers for other similar applications. The standard does not apply to devices used in flexible supply cables for the connection of household electrical appliances and the like to their supply. The introduction of requirements for mini-couplers for 440 V three phase
33、is under consideration. It should be borne in mind that aspects of product liability will have to be considered in conjunction with the use of mini-couplers. 2 Definitions The following definitions apply for the purpose of this European Standard. 2.1 mini-coupler a device for the connection and disc
34、onnection of flexible cables in the electrical mains supplied installation in road vehicles. It can consist of the following four parts: a connector, a part of a mini-coupler with contact tubes, which is integral with a flexible conduit and a three core flexible cable. an outlet, a part of a mini-co
35、upler with contact tubes, which is integral with a piece of electrical equipment. a plug, a part of a mini-coupler with contact pins, which is integral with a flexible conduit and a three core flexible cable. an inlet, a part of a mini-coupler with contact pins, which is integral with a piece of ele
36、ctrical equipment. 2.2 rated voltage the voltage value assigned to the mini-coupler by the manufacturer 2.3 rated current the current value assigned to the mini-coupler by the manufacturer Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 06 07:18:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 5

42、urroundings. In general, compliance is checked by carrying out all the relevant tests specified. 4 General notes on tests 4.1 Tests according to this standard are type tests. 4.2 Unless otherwise specified, the specimens are tested as delivered and under intended conditions of use, at an ambient tem
43、perature of (23 5) C. For the testing, the specimens intended for connection by flexible cable shall be equipped with a flexible cable, at least 0,5 m long and enclosed in a flexible conduit. 4.3 The tests are carried out as specified in Annex B. 4.4 Unless otherwise specified, mini-couplers with co
44、ntact tubes and those with pins are tested separately. 4.5 When, for a particular test, a mating mini-coupler is necessary, this mini-coupler shall be in accordance with the relevant standard sheet. For the purpose of testing to this standard no gauges are considered to be necessary. 4.6 The neutral
45、 circuit, if any, is treated as a pole. 4.7 For the tests carried out on one specimen, a mini-coupler is deemed to not comply with the requirements of this standard if there is a failure in one or more of the tests. For the tests carried out on three specimens a mini-coupler is deemed not to comply
46、with the requirements of this standard, if there are more failures than that of one specimen in one of the tests. If one specimen fails in a test, that test and those preceding, which may have influenced the result of that test, are repeated on another set of specimens, all of which shall then compl
47、y with the repeated tests. In general, it will only be necessary to repeat the test which caused the failure. The applicant may submit, together with the number of specimens specified in Annex B, the additional set of specimens which may be needed should one specimen fail. The testing laboratory wil
48、l then, without further request, test the additional specimens and will only reject if a further failure occurs. If the additional set of specimens is not submitted at the same time, a failure of one specimen will entail a rejection. 4.8 Mini-couplers integrated in or incorporated in an appliance or
49、 equipment are tested under the conditions of use of the equipment, the number of specimens then being the same as the number of specimens of equipment required according to the relevant standard for the equipment. 5 Marking 5.1 Mini-couplers shall be marked with: 16 A, 250 V; either the name, trade mark or identification mark of the manufacturer or of the responsible vendor; type reference, which may be a catalogue number; symbol for degree of protection by enclosure.
