Under safety chapter you can find the sar value. That means that it was measured, as the law requires.
I expect the same for jolla C- and there is no reason why they should not have been doing that.

Various governments have defined maximum SAR levels for RF energy emitted by mobile devices:
◾United States: the FCC requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal.
◾European Union: CENELEC specify SAR limits within the EU, following IEC standards. For mobile phones, and other such hand-held devices, the SAR limit is 2 W/kg averaged over the 10 g of tissue absorbing the most signal (IEC 62209-1).
◾India: switched from the EU limits to the US limits for mobile handsets in 2012. Unlike the US, India will not rely solely on SAR measurements provided by manufacturers; random compliance tests are done by a government-run Telecommunication Engineering Center (TEC) SAR Laboratory on handsets and 10% of towers. All handsets must have a hands free mode.[4]

From wikipedia

It seems that india's law is more efficient than US one, with more controls,at least in theory (not sure about reality).
Also it seems that indian and european law require a different test (first one on 1 gr of test tissue, second one on 10 gr) so maybe they cant use the same test used for intex device in india. I dont know if there is a way to convert the value without re testing, and if this is accepted from eu law,though.
