从高温拉伸试验设备、试样规格、试验过程和试验结果处理等方面对ASME和RCC-M规范中材料高温拉伸试验部分进行了对比和总结。结果表明：ASME和RCC-M规范采用了完全不同的试样规格，ASME更多考虑试样规格和试验温度对拉伸试验结果的影响，对试样的测量精度要求更高、保温时间更长；两者要求的加载速率范围相近，对试验结果的修约侧重点不同。

The part of elevated temperature tensile test of materials in ASME and RCC-M specifications were compared and summarized in the aspects of elevated temperature tensile test equipment, sample size, test process and test result treatment. The results show that the specifications of ASME and RCC-M were quite different. For ASME more consideration was given to the effect of sample size and test temperature on the tensile test results, and it required higher accuracy and longer holding time. The range of loading rate required by the two specifications was similar, and the emphasis of the revision of the test results was different.
