_________
1/ Relay shall be capable of switching low level while switching any of the other rated loads on adjacent contacts.
2/ 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.
