23、g and short-circuiting equipment. For this type of cable no rated voltage is given as such cables are exclusively intended for earthing and short-circuiting equipment. The particular types of cable and their code designations are specified in Clause 6 of this standard. The test methods specified in

24、this standard are given in EN 50395, EN 50396, IEC 60811 and IEC 62230. NOTE In addition to the requirements given in this standard, mechanical requirements and requirements for the marking for the complete equipment should be taken into account. These requirements can be found in IEC 61230. 2 Norma

34、urposes of this document, the following definitions apply. 3.1 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 application NOTE

35、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, design or type of manufacturing process which might change the performance characteristics. 3.2 sample tests symbol S tests made on samples of completed cable,

36、or components taken from a completed cable, adequate to verify that the finished product meets the design specifications 3.3 routine tests symbol R tests made on all production cable lengths to demonstrate their integrity EN 61138:2007 6 4 General requirements for the construction of cables 4.1 Cond
