France: Water/Diesel Emulsions
This summary covers historical French fuel emulsion specifications that are no longer in effect.
Water-diesel emulsions which comply with the following specification were eligible for a reduced excise duty rate in France from 1999.01.01 to 2006.12.31 [6259][6260][6261].

| * Sulfur = S (100 - y) / 100, where S - sulfur (mg/kg) in EN 590 conforming diesel fuel, y (% m/m) water content of the emulsion † Antifreeze additives are allowed for winter grade, provided the total water content is unchanged |
