Which IPC specification will show the minimum clearance from conductive
pattern to mechanical hardware such as swage standoffs?

Right now I have approximately 0.025in (0.635mm) from via pad edge to
standoff lip edge, and want to make certain that distance will be
sufficiently robust for production.

The manufacturers' datasheets don't specify a recommended clearance, and
neither do the IPC-222X series specs.

Thanks,
