摘　　要：目前,国际电工委员会(IEC)相关标准中尚未规定射频同轴电缆发热稳定性的试验方法。通过对IEC相关标准的研究,分别给出了等时间测试和等温升测试这两种确定射频同轴电缆发热稳定性试验方法,并进行了比较。指出了不同材料绝缘或护套的射频同轴电缆宜优先采用的发热稳定性试验方法,以期促进研发生产厂商进行预先研究。As of this writing,there is no specified determination method of thermal stability test for RF coaxial cables in the IEC relevant standards.With the study results on this issue,two thermal stability determination methods,as well as equal-time measurement and equal-temperature rise measurement,are introduced and compared,respectively.For the purpose of preliminary work of R&D manufactories,the recommended test methods are concluded from the insulation or sheath of different materials for RF coaxial cable.
