Does BS 4800 publish official RAL Classic equivalents?

No. These are computed nearest matches — every BS 4800 colour compared against every RAL Classic colour using the CIEDE2000 colour-difference formula, then ranked by distance. They are not official conversions, and where no close equivalent exists the chart says so.

How many BS 4800 colours have a close RAL Classic equivalent?

50 of the 116 BS 4800 colours in this chart have a RAL Classic equivalent within ΔE 5 — close enough that most people would struggle to tell them apart on a wall.

BS 4800 → RAL Classic conversion chart

This chart lists all 116 BS 4800 colours with their nearest RAL Classic equivalent, ranked by colour distance (ΔE, CIEDE2000 — lower is closer). 50 of 116 have an equivalent within ΔE 5, which is close enough that the difference is hard to spot once paint’s on the wall. Where the nearest RAL Classic colour is ΔE 8 or more there is no close equivalent — the nearest is still shown for reference, clearly labelled. Standard-system hex values are widely-cited sRGB approximations; physical reference chips remain authoritative for colour-critical work.
