This

41、Part 1 specifies the general requirements applicable to these cables, unless otherwise specified in the particular sections of this HD. Test methods specified are given in EN 60228, EN 60332-1-2, EN 60811, HD 605 and in IEC 60229, IEC 60840, IEC 60885-2 and IEC 60885-3. Attention should be drawn to

42、the fact that a significant number of sections include references to long term tests which are collected in HD 605. These long-term tests are considered as necessary and reflect the best available knowledge for the existing cable design. They are related to specific designs and different philosophie

43、s concerning adequate measures against the influence of water. However it is the firm intention to reduce this large number of different tests, but more experience should be gained before starting to rationalise this important matter. The particular types of cables are specified in Parts 5 to 9. NOT

44、E Cables originally in Parts 3 and 4 have now been withdrawn. 1.2 Object The objects of this Harmonisation Document are: - to standardise cables that are safe and reliable when properly used, in relation to the technical requirements of the system of which they form a part; - to state the characteri

45、stics and manufacturing requirements which have a direct or indirect bearing on safety; and - to specify methods for checking conformity with those requirements.

49、 Tests classified as Sample (S) or Routine (R) may be required as part of any type approval schemes. 2.2.1 Type tests (Symbol T) Tests required to be made before supplying a type of cable covered by this HD on a general commercial basis in order to demonstrate satisfactory performance characteristics to meet the intended application. 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 material, design or type of manufacturing process which might change the performan
