The terminology 'hard' vacuum is not quantitative; there are arguments that state a hard vacuum is 1 Torr while others state it at .01 Torr.
It is easier to refer to vacuum in terms of either Torr, Microns, or Inches of Mercury; these terms are more commonly found on the gauges, equipment and charts used in AC.

Knowing that the clear majority of our audience would take the term as being generic to the forum subject matter I saw, and still see, no need to be definitive beyond that.
The forum subject matter is not electronic e-beam technology, only about pulling a "hard" vacuum on an automotive A/C system.
If there was anyone other than yourself that needed more definitive term(s) please accept my sincerest apology.
