BS EN 16709 is a safety standard on high FAME diesel fuel (B20 and B30).
BS EN 16709 specifies requirements and test methods for marketed and delivering high FAME (B20 and B30) diesel fuel for use in diesel engine vehicles designed or subsequently adapted to run on high FAME (B20 and B30) fuel. High FAME (B20 and B30) diesel fuel is a mixture of up to 20 % (V/V) in total and up to 30 % (V/V) in total respectively fatty acid methyl esters (commonly known as FAME) and automotive diesel fuel.
Note 1: For maintenance and control reasons, high FAME (B20 and B30) diesel fuel is to be used in captive fleets that are intended to have appropriate fuel management.
Note 2: For the purposes of BS EN 16709, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
BS EN 16709 on high FAME diesel fuel (B20 and B30) is relevant to:
Automotive fuel is a liquid fuel, gasoline, or distillate, whose combustion is used to supply chemical energy to provide the power of an automotive vehicle.
BS EN 16709 is intended to cover fuels for use in a captive fleet application for designated vehicles. A captive fleet is defined as a group of vehicles that use dedicated facilities and logistics for supply and storage of their fuel only accessible for them. High FAME (B20 and B30) fuel may contain from 14,0 %(V/V) up to 20,0 %(V/V) or from 24,0 %(V/V) up to 30,0 % (V/V) of FAME. For climate-dependent requirements, options are given in BS EN 16709 to allow for seasonal grades to be set nationally. The options are for temperate climates with six CFPP (cold filter plugging point) grades and for arctic or severe winter climates with five different classes.
Overall, BS EN 16709 is useful as it describes two fuel grades in the range of (14 – 20) % (V/V) and (24 – 30) % (V/V) of fatty acid methyl ester (FAME) in diesel fuel to be used in the captive fleet application for designated vehicles), as it is not suitable for all vehicles.
