47、est:9.2.1 With the contacts at ambientroom temperature, a direct current of 1.0 A from a constant current source shall be passedthrough one half (for example, the (the positive leg) of a mated connector pair (See Fig. 2). The voltage drop across that leg ofthe mated pair shall be measured and record

The average of the two measured voltage drops shall be calculated to eliminate thermoelectrical anythermoelectric effects. The contact resistance in ohms is then computed by dividing the averag

49、e drop in volts by the current inamperes.9.2.2 The entire procedure of 9.2.1 is then repeated for the other half (negative (the negative leg) of the same mated connectorpair.9.2.3 The contact resistance value for each leg must be within the limit given in Table 3.9.2.4 Alternate test methods may be used if agreeable to both the supplier and the purchaser.
