摘　　要：主要阐述了目前国内防爆电机表面温度的测试方法 ,并与美国UL 674标准所规定的温度测试方法进行比较 ,从而了解其两者的差异。我国防爆标准规定的温度测试方法与欧洲标准及IEC标准基本相同 ,适用范围较广 ;而美国UL 674标准规定的温度试验方法较严酷 ,且试验周期长 。The author mainly expounds the testing method for surface temperature of explosion-proof motor which adopted in home now. Comparing with that method in UL 674, the differences are clearly present. The temperature test specified in GB is fundamental the same with that in Europe standard and IEC standard. Whereas, the test method specified in UL 674 is quite severe, and the test period is longer.
