Coronavirus and temperatures
They only tested 3 heat treatment regimens: 56C/30min, 60C/60min, 92C/15min (6 if you consider the &quot;with BSA&quot; and &quot;without BSA&quot;, but only 3 combinations of temperature and time). They didn't measure the time required at certain temperatures to get to a certain level of inactivation. It seems they chose some of these particular protocols because they have been recommended in the past for other viruses.
They don't really have sensitive enough data to compare the 56C/30min to the 60C/60min or really enough to do any sort of statistical comparison whatsoever (as far as I can tell they only tested a single sample of each); yes, you can say they were roughly as effective, but it would be a leap to say 56C is the same as 60C.
