Derek, I agree with you. I also checked CISPR22, only the height is mentioned.

The deficiency is Bogus. Sincerely, Derek Walton.

For this reason, unless the accreditation certificate bears a restriction note, I support the auditor's comment. From the other point of view, many manufacturers' laboratories are for internal use only, including my employer's. For this reason, the auditor may be willing to accept the smaller size of the table. The question is how to determine if the laboratory is for internal use only (for testing certain type of products). An example is Alcatel-Lucent's EMC laboratory in New Jersey, USA. It opens to the general public.

We have a table smaller than the standard requirement of 1.5m x 1m since our products are small, typically 10cm x 10cm x 10cm. The height of our table was 0.8m. The auditor wanted us to change the table size to follow the standard. What does it matter since we never use the extra space on the table? I do agree we must keep to the height requirement since the floor is a ground plane and thus it sets a fixed capacitance to the EUT and also controls the lengths of any attached cables. Can we reject or challenge the auditor's request? Has anyone experience the same situation?
