Upon completion of the initial visual examination and dimensional check, the resistors were weighed and the weights were recorded. The measurement of insulation resistance, performed with a megohmmeter, indicated infinity for each resistor. The dielectric strength test was performed with a high potential a-c dielectric strength tester. The test voltage was applied with no evidence of leakage or breakdown in any case. A wheatstone bridge was used to measure the d- c resistance of each resistor. All the resistors were well within their specified tolerance. The resistance-temperature characteristic test was performed in a temperature chamber at --67 to 302 c- F. The resistance of each was measured with a wheatstone bridge at 9 temperatures. The resistors exhibited a negative temperature coefficient, but remained within allowable tolerances. Upon completion of vibration and shock, the d-c resistance, dielectric strength, and insulation resistance, each resistor was measured. There was no evidence of damage in any case. (auth)
