The test specimens shall be kept at room temperature for not less than 30 minutes prior to the tests. 6.1.2 Heat Resistance Specime

45、ns of insulated wire, each having a length of 12 inches plus the length required for winding on the mandrel, shall be placed in an air-circulating oven at the temperature specified in Table 5-1 for the applicable wire type for a period of 96 hours. They shall be removed from the conditioning chamber

46、 and allowed to return to room temperature. Each specimen shall be examined for cracks. The length of exposed conductor, if any, at each end of the specimen shall be considered as shrinkage of the insulation. In no case shall the shrinkage at either end exceed a maximum value of 1/8 inch. Following

47、the oven aging, specimens shall be wound tightly around a mandrel approximately, but not more than three times the overall diameter of the wire, for five close turns and removed as a helical coil. Slight discoloration shall be considered normal and acceptable. The coiled sections shall then be subje
