General This Harmonization Document has been prepared by the secretariat of Technical Committee 61 in accordance with the decisions taken by TC61 during its meetings held in October 1972, December 1973 and September 1974 in Arnhem. During th
11、e last mentioned 2 meetings, the results of the Enquiry Procedure in the member countries of the previous versions of this document, CENELCOM 61(Se)04/72 of December 1972 and CENELEC 6i(SEC)40/74 of February 1974, were discussed. It was decided to publish and implement this document as HAREIONLZATIO
12、N DOCUMEhT in the member countries indicated on the front page on 1975.07.01. This was confirmd by the Council during its meeting held in November 1974 in Rome. During this meeting the Council decided also that conflicting non-harmonized national standards should be removed before 1977.07.01. This H

34、OOOWL 1 m February ! 975, United Kingdom (Wiring Rules): Class I appliances provided with a plug complying.with CEE- Publication 7 are not allowed. Therefore such appliances supplied with a flexible cable or cord do not require to be fitted with a plug. 826c Denmark (Heavy Current Regulations C23 g2
35、30Sh): The terininal shall be placed in such a way that internal wires, during replacement of supply cble or cord, have no possibility of being squeezed or exposed to harmful influence e.g. through pull, twist or sharp bendings. Loose terminals and terminals placed on e.g. lids or parts which are mo
36、vable without the use of a tool after covers have been removed for replacement of supply cable or cord, are not . permit ted. 1. This requirement need not to be complied with in case the terminals for supply connection are placed in housings which are entirely of insulating material or which have in
37、sulation between the interior of the housing and accessible metal parts and in which there are no parts which are intended for being connected to earth. This relaxation does not apply to equipment of Class I and Class 01. For equipment of Class O the said insulation shall at least be functional insu
38、lation, and for equipment of Class II it shall at least be reinforced insulation. Such insulation shall also be found in places where cords or cables may get jammed. , 230a Denmark (Heavy Current Regulations C23 g2316b and c) : External parts of insulating material shall in addition be resistant to
39、fire. Compliance is checked by the following test, which is not made on parts of ceramic material. The insulating parts are subjected to a test made with an electrically heated conical mandrel in an apparatus as shown in Figure 9. The mandrel is inserted into a conical hole reamed in the part to be
40、tested in such a way that portions OL the conical part of the mandrel of equal length protrude from both sides. The sample is pressed against the mandrel with a force of 12N. The mandrel is heated to a temperature of 3OOOC in approximately 3 minutes and is maintained within 1OoC of this value for 2
41、minutes. The temperature is measured by means of a thermocouple inside the mandrel. During the test, sparks of about 6 mm in length are produced at the upper surface of the sample where the mandrel protrudes, by means of a high-frequency spark generator. Neither the sample, nor any gases produced du
42、ring the heating, shall be ignited by the sparks. . After the conclusion of the test the sample shall not have moved on the mandrel by more than 3 mm (A longer movement may be accepted where it is considered reasonable). If the material by adaptation to the mandrel is wealcened to such an extent tha
43、t the movement on the iiiandrel during the test is likely to be caused by the above-mentioned weakening the test is repeated with a mandrel with a different dianeter -5- -5- HD 250 = February 1975. or possibly somewhere else on the material. It may be permitted that thermoplastic material does not p
44、ass the hot mandrel test, if the use of said insulating material gives special advantages, Howeverj such a permission is only obtainable, if the material does not burn violently as for example celluloid, 830b Denmark (Heaw Current Regulations C23 82316b and c): If insulating parts retaining live par
45、ts in position in addition are external parts forming the enclosure of the appliance, the prescribed hot mandrel test is replaced by the hot mandrel test mentioned in 830a, but with a temperature of 5OOOC and with a maximum movement on the mandrel of 2 mm. It may be permitted that thermoplastic mate
46、rial does not pass this hot mandrel test, if the use of said insulating material gives special technical advantages. However, such a permission is only obtainable, if the material is self- extinguishing. The material is deemed to be self-extinguishing if the following test is passed: The test is mad
47、e on 10 samples, and all samples shall with- stand the test. The test is made in still air with the aid of a Bunsen burner, having an opening of 9 mm and being supplied from the town gas. The flame of the burner is adjusted to an overall length of 10 cm and a cone length of 5 cm, The burner is held
48、at an angle of 45O The sample is held in one of the positions which are deemed to be most unfavourable for passing the test (the same position need not be used for all samples), and the sample is placed in this position with its lower end in the middle of the flame, the distance between the sample a
49、nd the opening of the burner being 3,5 cm. The flame is applied for 10 seconds. Any burning of the sample shall be quiescent and shall not spread appre- ciably; any flame shall be self-extinguishing vithin 30 seconds after the removal of the flame of the burner. Burnjag drops, if any, which are falling on a horizontal wooden board placed 20 cm below the sample, shall stop burning as soon as they touch the board. with the horizontal. g3la Germany (Bundesgesetzblatt 12 1997 A Nr, 100 Anhang II, Ausg. 28.9.1971): The use of carbon tetrachlorid
