Dear Brian, We, as I stated, are all the EMC Assessors with contract with A2LA at that moment, no publication but many of those guys are also sitting on the A2LA accreditation Council and would apply this rule to the benefit of the lab if an assessor do not follow it.
It is applicable to anything an assessor can measure on site and decide to cite a deficiency or not in particular distances, like in the topic of this subject. If you prefer arbitrary or, worse, no tolerance at all, fine... Just let me know...
