21、D21 applies to rigid and flexible cables with insulation and sheath if any, based on polyvinyl chloride, of rated voltages Uo/U up to and including 450/750V used in power installations of nominal voltage not exceeding 450/750 V A.C. - Note - For some types of flexible cables, the term “cord“ is used
22、. This Part 1 specifies the General Requirements applicable to these cables. The test methods specified are given in Part 2 of this HD, in HD 405 Part 1 and HD 505. The particular types of cables are specified in Part 3 onwards c.; HD, and are hereafter referred to as “the particular specifications“
23、. The code designations of these types of cables are in accordance with HD 361. 1.2 Object The objects of this Harmonization Document are to standardize cables and cords that are safe and reliable when properly used, to state the characteristics and manufacturing requirements directly or indirectly
24、bearing on safety, and to specify methods for checking conformity with those requirements. 1.3 Common Marking The Common Marking (4HARe) signifies that the manufacturer has been assessed and his production is subjected to continuing surveillance in accordance with the technical procedures by a recog
25、nised national Approval Organisation which is a signatory to the ?Agreement on the use of the Common Marking for cables and cords complying with Harmonised Standards. If Compliance with this Harmonization Document may be certified by the application of the agreed technical procedures for granting th
26、e Common Marking (*O, which are the recognised means of ensuring that a manufacturer is competent and takes all reasonable care to produce cables complying with this HD. The Common Marking may be used, under these conditions, by manufacturers in countries which have implemented this HD and in which
27、the national Approval Organizations are signatories to the Agreement. Note: See Appendix 2 to Part 1 for guidance on National Marking (*) These are given in Appendices 4 and 5 of the “Agreement on the use of a Commonly Agreed Marking for Cables and Cords complying with Harmonised Specifications“. -,

The same term also designates Type of compound The category in which a compound is placed according to its properties, is determined by specific tests. The type designation is not directly relate
30、d to the composition of the compound. Definitions relating to the tests Type tests (Symbol T) Tests required to be made before supplying a type of cable covered by this standard on a general commercial basis, in order to demonstrate satisfactory performance characteristics to meet the intended appli
31、cation. These tests are of such a nature that, after they have been made, they need not be repeated unless changes are made in the cable materials or design which might change the performance characteristics. Sample tests (Symbol S) Tests made on samples of completed cable, or components taken from
32、a completed cable adequate to verify that the finished product meets the design specifications. Routine tests (Symbol R) Tests made on all completed lengths of cable or as appropriate during manufacturing. Rated voltage The rated voltage of a cable is the reference voltage for which the cable is des
33、igned, and which serves to define the electrical tests. The rated voltage is expressed by the combination of two values Uo/U, expressed in volts: UO being the r.m.s. value between any insulated conductor and “earth“ (metal covering of the cable or the surrounding medium); U being the r.m.s. value be
34、tween any two phase-conductors of a multicore cable or of a system of single-core cables. -,-,- I 3L104583 0035239 3 SPI - 6 - HD21.1S2 - REPRINT In an alternating current system, the rated voltage of a cable shall be at least equal to the nominal voltage of the system for which it is intended. 3. T
35、his condition applies both to the value U , and to the value U. In a direct current system, the nominal voltage of the system shall be not higher than 1.5 times the rated voltage of the cable. - Note: The operating voltage of a system may permanently exceed the nominal voltage of such a system by 10
36、%. a 10% higher operating voltage than its rated voltage if the latter is at least equal to the nominal voltage of the system. A cable can be used at Marking 3.1 Indication of origin Cables shall be provided with an identification of origin consisting of: 1. Either the manufacturers identification t
37、hread, 2. Or the continuous marking of the manufacturers name or trademark, or (if legally protected) identification number, by one of the three following alternative methods; a) Printed tape within the cable; b) Printing, indenting or embossing on the insulation of at c) Printing, indenting or embo

39、n or on a tape. 3.2 Durability Printed markings shall be durable. Compliance with this requirement shall be checked by the test given in Sub-clause 1.8 of Part 2. 3.3 Legibility All markings shall be legible. The colours of the identification threads shall be easy to recognize or easily made recogni
40、sable, if necessary by cleaning with petrol or other suitable solvent. -,-,- - 7 - HD21.1S2 - REPRINT 3.4 Common Marking If the Common Marking (4HARP) is used, it shall be as specified in the “Agreement on the use of the Common Marking for cables and cords complying with Harmonized Specification“.

Core identification The cores shall be identified by colours, achieved by the use of coloured insulation or by a coloured surface. Each core of
43、 a multicore cable shall have only one colour except the core identified by a combination of the colours green and yellow. In multicore cables, the colours green and yellow shall not be used separately as single colours. The colours shall be clearly identifiable and durable. Durability shall be chec
