Labeling
indicates that fuel dispensers must have, in a perfectly visible form, the type of product they dispatch. In the case of diesel B2 (diesel containing up to 2% v/v of biodiesel) or diesel B5 (diesel containing up to 5% v/v of biodiesel) being supplied, the words “diesel B2” or “diesel B5” must be indicated on the legend of the pumps or dispensers, as appropriate.
