The quality of services may differ on the basis of their location as the service requirements might not be well defined

Shaver transformers incorporating electronic circuits are also covered by BS EN 61558-2-5

Method A: The temperature is cycled at intervals between a high temperature for ageing and a low temperature for checking the sealing force at this low temperature

This International Standard gives requirements for direct current relays intended for safety-related applications in railway signalling installations

The time of ageing has been added to the test report
