随着世界科学技术的飞速发展,对产品的质量和检验方法标准要求越来越高。为了迎头赶上世界新的工业革命,加速四化建设,我国正积极采用或参照采用国际标准(ISO) 及工业先进国家的标准。下面仅介绍八个国家的金属高温持久试验方法标准的概况。 1.国际标准ISO R206-1961“高温下钢的蠕变持久试验”。适用于单试样和多试样试验机的试验。温控精度:600℃为±3℃、600～800℃为±4℃、800～1000℃为±6℃,温度测量装置灵敏度为1℃。试验机所示负荷精度为±1％。在数据处理中,使用外推方法应十分详细地说明所采用的精确方法。在任何情况下,外推超过10倍的试验持
With the rapid development of science and technology in the world, the quality of products and testing methods require more and more standards. In order to catch up with the new industrial revolution in the world and speed up the construction of the four modernizations, our country is actively adopting or referring to the standards that adopt international standards (ISO) and advanced countries in the industry. The following is only an overview of eight countries, the standard test method of high temperature metal. 1. International Standard ISO R206-1961 “Long-term creep test of steel at high temperature”. Suitable for single and multi-sample test machine test. Temperature control accuracy: ± 600 ° C to ± 3 ° C, 600 ~ 800 ° C ± 4 ° C, 800 ~ 1000 ° C ± 6 ° C, temperature measuring device sensitivity of 1 ° C. The test machine shows the load accuracy of ± 1%. In data processing, the use of extrapolation methods should describe in great detail the exact method used. In any case, extrapolation of more than 10 times the test holder
