26、ted 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 standard may also be used for mini-couplers for other similar applications. The standard does not apply to de
27、vices used in flexible supply cables for the connection of household electrical appliances and the like to their supply. The introduction of requirements for minicouplers for 440 V three phase is under consideration. It should be borne in mind that aspects of product liability will have to be consid
28、ered in conjunction with the use of rnini-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 consis
29、t 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. a part of a mini-coupler with contact tubes, which is integral with a piece of electrical equipment. a part of a mini-coupler with con
30、tact pins, which is integral with a flexible conduit and a three core flexible cable. a part of a mini-coupler with contact pins, which is integral with a piece of electrical equipment. - an outlet, - a plug, - an inlet, 2.2 rated voltage The voltage value assigned to the mini-coupler by the manufac
31、turer. 2.3 rated current The current value assigned to the mini-coupler by the manufacturer. 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
32、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 cree
33、page 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. 3404583 004383b 462 Page 6 EN 50066:1992 2.6 2.7

35、 in the room in which the device is installed or used. 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 S). General require
36、ment 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. General notes on tests Tests according to this standard
37、are type tests. Unless otherwise specified, the specimens are tested as delivered and under intended conditions of use, at an ambient temperature of (23 f 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 e
38、nclosed in a flexible conduit. The tests are carried out as specified in annex B. Unless otherwise specified, mini-couplers with contact tubes and those with pins are tested separately. When, for a particular test, a mating mini-coupler is necessary, this minicoupler shall be in accordance with the
39、relevant standard sheet. For the purpose of testing to this standard no gauges are considered to be necessary. The neutral circuit, if any, is treated as a pole. 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 fai
40、lure 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, whic
41、h 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 o specimens Specified
42、 in annex 8, the additional set of specimens which may be needed should one specimen fail. W 3404583 0043837 3T9 m Page 7 EN 50066 992 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 s
43、pecimens 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
44、of equipment required according to the relevant standard for the equipment. 5 Marking 5.1 Mini-couplers shall be marked with: - 16A, 250V - either the name, trade mark or identification mark of the manufacturer or of the responsible - type reference, which may be a catalogue number: - symbol for deg
45、ree of protection by enclosure. The marking of the rated current and the rated voltage may be as follows: vendor; 16/250- or - 16 250 Mini-couplers need not be separately marked if they are integrated or incorporated in a piece of electrical equipment, as then the marking requirements of the relevan
46、t standard for the equipment apply * 5.2 Marking shall be durable and easily legible. Compliance is checked by inspection and by rubbing the marking by hand for 75 s with a piece of cloth soaked with test-fuel as specified in IS0 781 7, liquid C. After the test, the marking shall still be legible. 5
47、.3 Devices incorporating mini-couplers shall be accompanied by an instruction for installation specifying how to mount the device and its cable, if any, within the vehicle with regard to protection against e.g. the risks for thermal, chemical and mechanical damages, or liquid influences. Compliance
48、is checked by inspection and verification of the contents of the instruction sheets. 6 7 Preconditioning Before mini-couplers are tested as specified in this standard, they are subjected to the following preconditioning. The specimens are suspended freely in a heating cabinet, ventilated by natural
49、circulation, in an atmosphere having the composition and pressure of the ambient air. The specimens are kept in the cabinet for (1 68 f 7) h at a temperature of (1 O0 f 2) “C and are then allo wed to cool down to (23 f 5) “C. Dimensions Mini-couplers shall comply with Standard Sheets 1 or 2 as relevant. Compliance is checked by measurement.
