摘要
主要对国标新、旧版本金属材料拉伸蠕变及持久试验方法在标准名称、引用标准范围、术语及定义、符号及说明、试验原理、试验设备、试验机环境温度、加热装置、试样、试样原始横截面积的测量、试验程序及试验结果等在技术内容和要求方面的变化进行了对比,对新版标准中变化部分的内容进行了分析和讨论,对标准下一步修订提出了意见。
The differences between the new and old versions of the national standards for metal tensile creep and stress rupture tests were compared and analyzed from the variations of the technical contents and requirements such as the standard name,reference standard scope,term and definition,symbols and description,test principle,testing equipment,environment temperature of test machine,heating apparatus,specimen,measurement of original cross section of specimen,test procedure and test results.The modified contents in new version were analyzed and discussed,and some opinions for the next revision of this standard were proposed.
