Annex A (normative) Double insulated resistors

States the characteristics of the resistors; the service conditions with which the power resistors have to comply; the tests intended for confirming that these conditions have been met and the methods to be adopted for these tests; the information to be marked on, or given with, the resistors. The object of this standard is to adapt the general rules given in IEC 60077-1 to power resistors for rolling stock in order to obtain uniformity of requirements and tests throughout the corresponding range of components and to avoid the need for testing to two different standards.
