18、s21 -,-,- HD 21.1 S4:2002 - 4 - 1 General 1.1 Scope HD 21 applies to rigid and flexible cables with insulation and sheath, if any, based on thermoplastic materials, of rated voltages Uo/U up to and including 450/750 V, used in power installations. NOTE For some types of flexible cables, the term “co
19、rd“ is used. This Part 1 specifies the General Requirements applicable to these cables. The test methods specified are given in Part 2 of this Harmonisation Document (HD), or in the common test methods for cables given in EN 50265, EN 50267, EN 50268 and EN 60811. The particular types of cables are
20、specified in Part 3 onwards of this HD, which are hereafter referred to as “the particular specifications“. The code designations of these types of cables are in accordance with HD 361. 1.2 Object The objects of this HD are to standardise cables and cords that are safe and reliable when properly use
21、d, to state the characteristics and manufacturing requirements directly or indirectly bearing on safety, and to specify methods for checking conformity with those requirements. 1.3 Common Marking 1.3.1 General The Common Marking () signifies that the manufacturer has been assessed and his production
22、 is subjected to continuing surveillance in accordance with the technical procedures by a recognised national Approval Organisation which is a signatory to the “Agreement on the use of a Commonly Agreed Marking for Cables and Cords complying with Harmonised Specifications.“ Compliance with this HD m
23、ay be certified by the application of the agreed technical procedures for granting the Common Marking 1), 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 co
24、nditions, by manufacturers in countries which have implemented this HD and in which the national Approval Organisations are signatories to the Agreement. NOTE See annex B to Part 1 for guidance on national marking. 1) These are given in Appendices 4 and 5 of the Agreement on the use of a Commonly Ag
