I've also looked over testers shoulders and seen things done wrong.
Often it was because they didn't what was SUPPOSED to be done. We all

Exactly. While assessors may look over paperwork, that does not actually mean
those involved in testing know what the standard to which they are testing
actually says or if they do that they actually test to them. Cannot tell you

Yes, but the standards I'm thinking of are core to the computer industry.
CISPR 22, CISPR 32, CISPR 24, ANSI C63.4. Really disturbing when you see key
things that aren't set up properly. It makes you wonder what the
qualifications are of the on-site assessors. Paperwork is usually fine, the
The only pathos there is we take ourselves so seriously that a suggestion
like that is rejected out-of-hand.

Pathos and tragedy, with a bit of comedy, in the EMC lab. Once had the sales
manager for a major lab say "we have never done that test but would give you a
good deal so we could get experience..."

ANSI Z535.4 is the standard for warning labels for equipment. Clarion, and
likely other vendors, have samples on their web page.

So I’m looking at the new NFPA 79 2015 (which you can view on-line for free

As long as assessment of labs is being done by people not even in the proper

One other area of concern, often overlooked, is the application of overvoltage
