I also had similar issues during audits. I was able to argue that it is impossible to have anything that is EXACTLY any dimension. At issue was the height above the ground plane for a 61000-4-6 conducted immunity test. I was able to back it up by finding precedence in the 61000-4-4 EFT standard stating the 10cm height +/- 10%. I'm sure there are some auditors that would not budge, though. I like the quote "EMC testing is like measuring Jello with a micrometer". Bob R.

Several years ago I had a similar issue: The table height was measured by (a well-respected) auditor and deemed to be 79.5cm, not 80cm. Several discussions followed regarding the accuracy/traceability of the auditor’s tape measure, validity of the deficiency etc. Initially I rejected the deficiency but after time just added a 0.5cm board to the table. When in business to make money it’s often easier and quicker to fix the perceived problem than to argue against it.
