The following new class structures were voted on by EphMRA/PBIRG in May/June 2017 and agreed in principle.  These structures will now be used in the next part of the development process which is the detailed refinement of the rules.  Please note that these new class structures are provisional at this time. 

The 2018 codes, descriptions and Guideline text will be finalised and published by the Committee at the end of 2017.  The new structures then come into effect from the beginning of 2018.
