Cold
2、Bend Test A straight specimen shall be reduced to a temperature of -40 C at a rate not to exceed 50 C/min. After maintaining this temperature for 3 h and while still at this low temperature, the cable shall be wrapped around the mandrel specified in Table II for 180 at the uniform rate of one turn i

A 610 mm sample shall be suspended taut in a horizontal position within a partia
5、l enclosure which allows a flow of sufficient air for complete combustion but is free from drafts. The tip of a 51 mm gas flame with an inner cone one-third its height shall then be applied to the center of the suspended cable. The time of application of the flame shall be 15 s. After removal of the

7、ed to an overload current sufficient to raise the conductor temperature to 150 +/- 2 C and to hold it there for a period of 30 minutes (thermocouple to be inserted into sample conductor stranding 457 mm from one end). After the overload test, cut 457 mm from each end of the cable and discard. The re
