fiabilité d'un relais

CONT: Pour étudier expérimentalement la fiabilité d'un relais, en particulier afin de déterminer s'il convient d'employer un matériau donné dans un relais, on soumet le relais à des cycles de fonctionnement à l'aide d'une table vibrante.

CONT: Relay reliability is demonstrated by performing life tests on a representative sample randomly selected from each manufacturing lot. Lot sizes vary to a maximum of about one week's production of a particular configuration. Generally, the testing is carried out at the maximum ambient temperature and at the rated contact loads in a controlled environment. The samples are cycled to the minimum rated life of the relay, and the failures are used to calculate the demonstrated reliability.
