说明电阻器的特性；功率电阻器必须符合的工作条件；旨在确认这些条件已得到满足的试验，以及这些试验将采用的方法；在电阻器上标记或给出的信息。 本标准的目的是使IEC 60077-1中给出的一般规则适用于机车车辆的功率电阻器，以便在相应的部件范围内获得一致的要求和试验，并避免需要按照两个不同的标准进行试验。

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.
