AsrIM E1742~ 2008 标准的质量级别设置规定 注:1) 透度计平板厚度与工件厚度的 自分 比。 (2) 关于质量级别选用 AST M E1742- 2008 标准的基本规定是 :如果 在图样或文件 中无规定 ,射线照相质量级别选用 2— 2T 。如果 回溯 到美 国军标 MIL-ST D-453B- - 1977 的规定 ,可以更清楚理解...
进行了分析讨论,并与ISO标准的规定进行了比较。结果指出,ASTME1742—2008标准基于 ASTME1025标准规定的射线照相质量级别,每个级别本身对各厚度并不是等价的,与工业射线 照相技术也不构成一个协调的系统。 关键词:射线照相;标准;灵敏度;质量级别 文章编号:100026656(2009)0920731207中图分类号:TG115.28文献标志码:A ...
