________
1/ For low level, the following shall apply:
a. During endurance and operational reliability testing, contact load shall be 10 to 50 microamperes, 10 to
50 millivolts open circuit voltage, 100 ohms maximum contact resistance.
b. Static contact resistance shall be performed at 50 mA maximum, 50 mV maximum.
2/ For all ER relays, the alternate low level test of operational reliability shall be used.
3/ For group A contact voltage drop test, high level testing shall be performed first, followed by low level testing.
The contacts shall not make or break the high level load.
4/ Relay shall be capable of switching low level while switching any of the other rated loads on adjacent contacts.
