This document will no longer be updated and may no longer represent standard industry practice. The original issue of this document was in December, 2011, and it has not been updated since tha

7、t time. Users of this document should refer any certification issues (e.g. exceptions listed on the certification report) to the cognizant engineering organization for their disposition. CAUTION: In many cases the purchaser is not the cognizant engineering organization (i.e. purchaser may be a sub t

8、ier supplier).AMS Committee D recommends that the following technically equivalent (e.g. properties, fit, form, function) specification be used for future procurement.
