Note:  Normal specifications represent the design specifications.  All
       units should be able to approximate these-some will exceed and
       some may drop slightly below these specifications.  Limit
       specifications represent the absolute worst condition that still
       might be considered acceptable; in no case should a unit fail to
       meet limit specifications.
