REPORT OF THE QUALIFICATION TESTING OF SNAP 10A FIXED RESISTORS
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)
