For products certified under BES 6001, the rating score (between 5 and 7) can be found in the Green Book Live. This is the rating that needs to be entered in the Mat 03 calculator.
The RSCS score that is entered into the Mat 03 calculator comes from the relevant table in Guidance Note 18. However, for BES 6001, the score is per certificate because 6001 works at different levels of rigour.
