2.Contact resistance: Contact resistance shall be less than 50 Milliohms at initial and 100 Milliohms after life test between a terminal of the socket and that of the mating plug; less than 30 Milliohms at initial and 60 Milliohms after life test between terminal of the socket in a closed circuited, when measured at a current of less than 100 Milliampere 1 KHz. The Mating plug use shall be
cleaned and free from oxidation film of the surface.
Insulation resistance between insulated metal parts shall be 100 Megohm or more at initial and
50 Megohm or more after cold test, hot test, and humidity test when measured with a 500 volts
D. C. insulation resistance meter.
4.Insertion and Withdrawal Force
The insertion and withdrawal force shall be 0.3 – 3Kgs at initial and 0.2 – 2Kgs after life test
with the gauge plug.
The terminal shall be capable of withstanding a force of 500 Gram applied in any directions for
10 second without loosing and breakdown..
