Default How is field strength specified?

Quick question... when someone tells you that their receiver provides
12dB SINAD (or whatever) with an incident field strength of, say,
20uV/m, is 20uV/m an RMS value or magnitude? Or isn't this
standardized enough that one should assume?

From some Googling RMS appears to be the standard, but I wanted to ask
some folks who really know...

(Back in school, in EM classes it was always magnitudes...)

Thanks,

The answer is revealed by finding Power Flux Density in terms of Electric
Field Strength and Magnetic Field Strength.
