This standard 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 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 disconnection 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-coupler 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 electrical 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 50066:1992 4 © BSI 01-2000 2.4 clearance the shortest distance in air between two conductive parts for the purpose of determining a clearance to accessible parts, the accessible surface of an insulating enclosure shall be considered conductive as if it were covered by a metal foil wherever it can be touched by hand or the standard test finger according to EN 60529, Figure 1 2.5 creepage distance the shortest distance along the surface of an insulating material between two conductive parts for the purpose of determining a creepage distance to accessible parts, the accessible surface of an insulating enclosure shall be considered conductive as if it were covered by a metal foil wherever it can be touched by a hand or the standard test finger according to EN 60529, Figure 1 2.6 ambient temperature the temperature of the air surrounding the mini-coupler 2.7 temperature rise the difference between the temperature of the relevant part of the mini-coupler, measured at the load specified by the test specification, and the temperature of the air in the room in which the device is installed or used 2.8 non-rewirable connector; non-rewirable plug an accessory so constructed that it forms a complete unit with the flexible conduit and the flexible cable after connection and assembly by the manufacturer of the accessory (see 11.5) 3 General requirement Mini-couplers shall be so designed and constructed that when used as intended their performance is reliable and without danger to persons or surroundings. 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 temperature 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 contact 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 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 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 comply 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 will 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 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 Vì 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. The marking of the rated current and
