George: - As you know Mil-C-28809B was canceled on 4/19/95 without replacement. The environmental tests of 28809 are closely related to the tests described by Mil-Std-810E. - Mil-Std-810E (Environmental Test Methods & Engineering Guidelines) was (the last I heard) being retained as a Test Method Standard pending action by ANSI to identify alternative or replacement private sector specs/stds. The Mil-Std may be available from some normal (Government) sources if it has not yet been canceled. - If you are unable to obtain a copy of 810E and need an alternative private sector Spec. then you might check with the EIA Standards Section (http://www.eia.org/eng/catalog/catindex.htm) as they have a number of standard methods listed (see EIA-186-7E or EIA-186-8E). - After identifying a viable alternative Spec. you need to discuss SPI/Block Change using the different specifications with your customers. - Pose any additional questions direct to [log in to unmask] Regards, Jim Moffitt
