AISI: American Iron and Steel Institute

ASTM: American Society for Testing Materials. (One of the biggest standard developers in the world)

 

The difference between these bodies is that AISI is only concerned with iron and steel products, as the name indicates. Whereas ASTM is concerned with several other products including pastics, rubber, fossil fuels, electrical and electronic devices and many more.
