QQZ325C Alive or Dead?
Is QQz-325-C obsolete? Shouldn't we be using B633 instead?
Thank you,

Ron, you are right: QQ-Z-325 was cancelled in March of 1982. The cancellation notice noted that there is a commercial standard covering the same material, ASTM B633. You can find the cancellation notice on the ASSIST website, at http://assist2.daps.dla.mil/quicksearch/.
