Applies to separable contacts used in the utilisation areaconsidered such as switching element for control circuits. Tworated voltages are taken into consideration: above (andincluding) 10 V (typically 24 V) where contacts are used forswitching loads with possible electrical erosion, such asprogrammable controller inputs, and below 10 V (typically 5 V)with neglible erosion, such as electronic circuits. It is aproposed method of assessing the performances of low energycontacts giving: useful definitions; general principles of testmethods which are to monitor and record the behaviour of contacts ateach operation; functional bases for the definition of a generaltesting equipment; preferred test values; particular conditions fortesting contacts intended for specific applications (such asswitching of PC inputs); information to be given in the testreports; interpretation and presentation of the test results.
