Are California Smog test requirements the same across the state and are they the same for all vehicles that are required to pass a smog test?

I just had my 1996 Mercedes C280 smog'd and my print out showed that my car could not go have a HC reading of higher than 51 at 15 MPH and not higher than 35 at 25 MPH.

However, murphysf's California Smog snippet showed that his car's max HC could have been 110 at 15 MPH and 77 at 35 MPH.
