"QQ-Z-325"



-----

2005

Should we be using this standard or should we use B633-98- - -I've read 325 was replaced by 633- -so we should adapt to 633 and rid ourselves of 325. . . correct or not?..thank you.

The cancellation notice for QQ-Z-325, dated March 9, 1982, says "Federal Specification QQ-Z-325C, dated August 18, 1976, is hereby canceled. An existing commercial standard which covers this material is American Society for Materials and Testing Standard ASTM B633 [affil link] ."

So it's not a hard supercession, meaning that your customers really should make a decision based on looking at the two documents. It would probably be easier to do if ASSIST posted the canceled QQ-Z-325 on the website, but they don't. My company has decided to use B633 as a direct replacement, but what others do is up to them.
