Railway applications. Fixed installations. Harmonisation of the rated values for converter groups and tests on converter groups1 Scope This European Standard provides requirements for some type tests which are significant only when made on the entire group. It provides also a basic relationship between compatible ratings of traction transformer and converter(s), in order to provide minimum requirements for the choice of their ratings. Moreover it gives the minimum values to be considered in order to choose switching devices with characteristics suitable for the converter

the detailed test procedure

Note: The tests given in BS 8442 are suitable for both initial type testing and production testing

the circuit breaker has become overloaded as the number of devices that are plugged into the circuit attempt to draw more electricity than what the circuit is designed to handle

Their chemical composition limits are specified in BS EN 573-3

Rounding off

This includes organizations that procure products and split them into smaller quantities

the proliferation of symbols without control and harmonization is undesirable and detracts from the effectiveness of using symbols to convey information for safety

Shutters and blinds must be tested separately and not in conjunction with a window or door
