适用范围：This part of IEC 60502 specifies the test requirements for type testing of accessories forpower cables with rated voltages from 3,6/6 (7,2) kV up to 18/30 (36) kV, complying withIEC 60502-2.Accessories for special applications, such as aerial cables, submarine or ship cables orhazardous situations (explosive environments, fire-resistant cables or seismic conditions),are not included.It is not necessary to repeat these tests, once successfully completed, unless changes aremade in the materials, design or manufacturing process which might affect the performancecharacteristics.Test methods are included in IEC 61442.NOTE This standard does not invalidate existing approvals of products achieved on the basis of national standardsand specifications and/or the demonstration of satisfactory service performance. However, products approvedaccording to such national standards or specifications cannot directly claim approval to this IEC standard. It may bepossible, subject to agreement between supplier and purchaser, and/or the relevant conformity assessment body, todemonstrate that conformity to the earlier standard can be used to claim conformity to this standard, provided anassessment is made of any additional type testing that may need to be carried out. Any such additional testing that ispart of a sequence of testing cannot be done separately.
