3.5.2 Low Level Circuit Resistance - The low level circuit

resistance shall not exceed the value specified in Table I when measured using a

Keithley Model 580 (or similar instrument) in the pulse mode and dry circuit conditions.

The following details shall apply:

(a)

Method of connection: see Figure 3.

(b)

Test current: 100 milliamperes maximum pulsed current.

(c)

Maximum open circuit voltage: 20 millivolts.

3.5.3 Insulation Resistance - The insulation resistance of

Mated/Unterminated connectors shall be not less than 50,000 megaohms (5,000

megaohms after exposure of the humidity environment described in paragraph 3.7.1)

when measured in accordance with MIL-STD-202, Method 302. The following details

shall apply:

(a)

Test condition: B (500 volts DC)

(b)

Special preparation: The connector shall not be terminated because of the type

of printed wiring board and the geometry of its land area will affect this

parameter.

(c)

Points of measurement: Between adjacent and opposing contact positions for

20 percent of connector population.
