Hi Peter: I concur with George: Check the CB Scheme website: http://www.cbscheme.org/ In particular, download the "white paper." This paper provides a reasonable description of the CB Scheme and its advantages. If this doesn't meet your needs, then I suggest you buy the IECEE documents mentioned in the white paper. You should also check the "CTL Decisions" as this takes you to the IMQ web site which has the CTL decisions plus other data produced by the CTL.
