IEC 60322:2001 pdf free download.Railway applications – Electric equipment for rolling stock – Rules for power resistors of open construction.
This International Standard gives the rules for all power resistors (for example, braking,heating, snubber and filter) board rolling stock irrespective of the circuit and the type of vehicle where they are used.
These resistors are generally of open construction and are used in polluted areas. The construction consists of resistor elements of grids, plates, strips, ribbons or wires.
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.
4 Product information
4. 1 General
An agreed specification should exist between the manufacturer and his purchaser containing general performance and test requirements in accordance with this standard.
4.2 Nature of information
The following information shall be given in the manufacturers catalogue or manuals for each resistor case or frame. It concerns the identification and the characteristics.
