ASTM

373527271

工作中遇到很多不常见的材料，俺喜欢寻根问底，最后发现几乎所有不同行业，不同功能，不同工况的材料最后都收编进入ASTM中了(军用的除外）。

A = Iron and Steel  Materials
B =  Nonferrous Metal Materials
C = Ceramic,  Concrete, and Masonry Materials
D = Miscellaneous Materials
E = Miscellaneous Subjects
F =  Materials for Specific Applications
G =  Corrosion, Deterioration, and Degradation of Materials

涵盖极其广泛，塑料，纤维，玻璃等等，上次遇到的ASTM首代就是个老虎。
光铁基材料A系列就有680个之多，比如300M就在A579里面。

玩工业，要通这个，

拉斯特

而且这些标准更新迭代特别快，说明鸟是真玩工业；汉爷有的标准漏洞百出，不过最近十几年或者二十年，很多都是equivalent ISO，这样标准制定者省事多了；
