I asked the same question at B+Q today. Apparantly the Dulux paint centres (we have one locally in Peterborough) have a "catalogue" which gives the RAL number for each Dulux colour. These "catalogues" are not available at the DIY store. As previous answer there is an on-line service but costs $9.99 per conversion which prices it out of the market for me.
The conversion to Ral of Pantone 311 is the number RAL 6027. The Ral conversion for Process Blue is Ral 5015.
The RAL number of the Pantone color Reflex Blue C is thought to be 5002. There is no exact matching when converting RAL colors to Pantone colors, but this is the closest blue to it.
5009
The RAL color system is for powder coating. You can request your ICI/DULUX paint salesman match RAL 7000 in any of their paints. There is no direct crossover, however there is sure to be a paint color in the ICI system that is close. You might try "Night Sky" I have referenced a web site that has conversions that might help you along with a direct link to the RAL 7000 color conversion.
The closest RAL color to Pantone 287C is RAL 5017, which is a dark blue shade.
