铸铁材料低温力学性能试验标准编写研究

摘要

The significance and necessity of drawing up the standards of static tension test and Charpy notch impact test at low temperature special for cast iron materials was described. Through analyzing and comparing the content of the latest editions of related national and international test standards for general metallic materials, as well as considering the speciality of cast iron materials, the subject of how to improve the suitability and application of the new standard was approached, and also some thinking and ideas to write the standard were provided.%阐述了编制铸铁材料低温静拉伸试验方法与低温夏比摆锤冲击试验方法标准的意义，通过对现行国内外通用试验规范的比较与分析，并结合铸铁材料的特性，对如何使编写的标准内容更有针对性与适用性进行了探讨，提出了一些编制标准的思路与设想。
