Yes our unit was certified under 15.219, the FCC was aware that our unit exceeded 15.209 limits (as many transmitters do under the 100mw, 3 meter limitation), the field strength readings were in the lab report. The lab gives detailed measurements on the intentional frequency level on a calibrated test range and the first 10 harmonics.
The reason for certification is so the user (and an inspecting FCC agent) can be comfortable knowing that the transmitter complys with FCC rules, certification requirements are available on the fcc.gov website.
On another subject, the antenna ground issue, I would like to point out to folks that I seem to get singled out for recommending that our customers ground the antenna circuit for lightning protection, when as far as I know, every other certified Part 15 AM transmitter manufacturer out there does their antenna the same way! For general safety and the quality of our unit we never considered not including lightning protection and for the lightning protection to work the antenna circuit must be properly grounded, same is true with all the other certified transmitters out there.
