My copy of GR-1089  ( Issue 2, dated  December 1997 says 8.5 V.m for the 
Conditional Requirement, not 10 V/m as you stated.

SR-3580 dated  November 1995 does mention 10 V/m, but then if you look at what 
it refernces, namely GR-1089, Criteria 16,18, it is 8.5 V/m. A typo or 
miscalculation? Who knows? 

If 10 V/m immunity is required, it is above and beyond what GR-1089
currently requires.
