As far as I know, the RWC is calculated by comparing the concentration of a disinfectant required to kill a certain number of germs in a certain period of time to the concentration of phenol required to achieve the same result in the same amount of time.

Overall it doesn't sound like a terribly useful measure considering the staggering biodiversity found in the world of germs.  It's really just a comparison to phenol's activity.  In fact, I believe it's also called the phenol coefficient.
