standards' revisions
(OP)
I'm looking for a standard drafting note to apply to our drawings that removes the need to write an ECO when the gov agency rev's the standard. I have looked through the Drawings Rq'mnt Manual however more input would be appreciated.
Example: MIL-STD xxx instead of MIL-STD-xxxA
Some note such as "all standards on drawing are revision verified prior to use" etc.
Thanks,
sds

It is entirely possible that a revision will alter some aspect of the standard that was important to you, making "latest revision" unsuitable for your purposes.
When you reference a standard it is your responsibility to:
a: Find out what the latest revision is at the time.
b: Actually read and understand it before referencing it.
c: Ensure that you are notified of revisions, and read and understand what has changed in the latest revision. Then determine if the "latest revision" is still suitable for you.
On projects lasting many years it is common for references without revision to be "the latest revision in effect at the date of notice to proceed." This prevents a moving target over time.

RE: standards' revisions
However, if you specify an anodic coating to aluminum alloy per MIL-A-8625 you usually have to specify the type and class of the coating to differentiate between chromic to sulphuric or hard anodize. Added to this you have to specify the class which differentiate between the sealing and dying options. Then you must specify the revision.
Newer version may change the type and class designation (as already happened before) but always give a conversion table from the old types and classes to the newer one.
