室温拉伸试验标准GB/T 228.1-2010应用解析

摘要

The changes of tensile specimens,testing machines and their performance control requirements were compared between the room temperature tensile test standard of GB/T 228.1-2010 and its previous version GB/T 228-2002.Some changes of regulations and requirements of the new version standard on the tensile strength and yield strength, as well as the matters needing attention in engineering application were analyzed in detail.A distinction was made between extension and elongation,and some concepts in the new and old standards were compared.%分析了室温拉伸试验标准 GB/T 228.1-2010相比上版标准 GB/T 228-2002在拉伸试样、试验机及性能控制要求等方面的变化,详细解析了新版标准中对抗拉强度、屈服强度规定及要求的一些变化以及工程应用中需要注意的事项,并对伸长和延伸进行了区分,对新旧标准中的一些概念进行了对比.
