Well done, Pete!
For about 25 years, I've been Vice-Chair of the AES Standards Committee
Working Group on EMC, a member of a half-dozen other WGs, and a
principal author of a half dozen Standards. These are International
Standards, so we often need to add clarifying language like this to
cover both differences in use of words between cultures.
It's not unusual for these documents to take 3-5 years to hammer out.
Our issues are not political, but simply achieving both a common
understanding of the technical issues involved, and getting the wording
to describe requirements in a manner that both they and the technical
issues are clearly understood.
A key example was use of "shielding enclosure" as the proper termination
point of cable shields, rather than talking about "grounding" it -- a
connection to Mother Earth does NOTHING to provide shielding or the
elimination of RFI.
