Railway applications. Electric equipment for rolling stock. Rules for power resistors of open construction Ingestion-build-209208 2 Evaluation of shielding effectiveness1 Scope and object This International Standard gives the rules for all power resistors (for example, braking, heating, snubber and filter) used in the power and auxiliary circuits on 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. NOTE
