一、前言随着我国四个现代化的进程,为适应生产的发展和科学实验水平的提高,我国第一台UJ—40型悬臂梁式冲击试验机去年由河北省承德市材料试验机厂研制成功。经有关部门组织鉴定,各项技术指标达到国家有关标准,同时也符合 ISO—R180国际标准,一九八○年已投入批量生产。这台新型的冲击试验机的诞生,为我国非金属材料的测试仪器填补了一项空白。
I. Introduction With the progress of the four modernizations in our country, the first UJ-40 Izod Impact Tester in China was successfully developed by Materials Testing Factory of Chengde City in Hebei Province in order to meet the development of production and the improvement of scientific experiment level . The relevant departments organize the identification, the technical indicators have reached the relevant national standards, but also in line with ISO-R180 international standards, has been put into mass production in 1980. The birth of this new type of impact testing machine for our non-metallic materials testing equipment to fill a blank.
