Where can I find test labs for FCC and other unintended radio emissions testing?
Many regulatory agencies maintain lists of certified labs, and most labs do multiple regulatory agencies.  Here are links to the lab search tool:


USA FCC https://apps.fcc.gov/oetcf/eas/reports/TestFirmSearchResult.cfm


Note you may wish to find a smaller local lab to "pre test" your product, prior to the final layout and case design.  This can save a lot of delay and hassle later.
