Inactive for New Design Documents

Q: Can inactive for new design specifications and standards be referenced in active documents that will be used in new design?
A: Generally, no. Having an active document means that it will likely be used in new designs in the future, as well as major modification and upgrades. You would want that active document to reflect the latest technologies, which is why we promote performance specifications instead of detailed specifications. So every effort should be made to avoid referencing an inactive for new design document in an active document. There may be a rare scenario, however, where an active document will be used to support an obsolete piece of equipment described in an inactive for new design spec, and it is necessary to reference the inactive document for interface purposes. For example, there might be an active spec for spark plugs that describes plugs that will be used in future, current, and obsolete engines. It may be necessary to reference an inactive for new design engine spec to describe the interfaces found in obsolete engines that are still in use.

Q: I am revising an inactive for new design specification. Do I have to designate it as DTL or PRF or can I leave the document identifier as is? Since this inactive for new design specification is referenced on many legacy drawings, I would rather leave the document identifier as is.
A: You do not have to change the document identifier to DTL or PRF when revising an inactive for new design specification.
