"New numbering system .... In order to accommodate future IEC changes it has been decided to have a 100 numbering system for UK regulations only. The means for example the current regulation 422.3.14 will become become 422.3.100 and regulation 422.3.6 will become 422.3.103 etc."
So 422.3.14 becomes 422.3.100 ... and 422.3.6 becomes 422.3.103? Er, lost me already.
