Just found this older thread which seems unanswered;
http://forums.coade.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=20492.

My question is what the OP of that thread asked in his last reply;
EN-13445 chapter 16 is not incorporated in PVElite/CodeCalc, where WRC and PD5500 are. Is there a change EN-13445 chapter 16 gets incorporated?
