FAME
Fatty Acid Methyl Ester (FAME) or biodiesel is a biofuel produced by transesterification of vegetable oils. It has similar properties to fossil Diesel fuel, and is therefore suitable for the operation of Diesel engines. The British Standard specification for Diesel allows a maximum FAME content of up to 7 vol.% (B7).

NOTES
a. See 5.5.1. in EN 14214:2012+A1:2014.
b. Density may be measured over a range of temperatures from 20 °C to 60 °C. Temperature correction shall be made according to the formula given in Annex B in EN 14214:2012+A1:2014.
c. See 5.5.2. in EN 14214:2012+A1:2014
d. If CFPP is •20 °C or lower, the viscosity shall be measured at •20 °C. The measured value shall not exceed 48 mm2/s. In this case, EN ISO 3104 is applicable without the precision data owing to non-Newtonian behaviour in a two-phase system.
e. See Annex A for precision data in EN 14214:2012+A1:2014.
f. Procedure A shall be applied. Only a flash point test apparatus equipped with a suitable detection device (thermal or ionisation detection) shall be used.
g. A 2 ml sample and apparatus equipped with a thermal detection device shall be used. See also 5.5.2. in EN 14214:2012+A1:2014
h. See 5.5.3. in EN 14214:2012+A1:2014
i. An additional determination method has been developed by CEN, but first needs to be assessed for actual field performance prediction [3].
j. For use as an extender to diesel fuel Table 3 applies in EN 14214:2012+A1:2014.
k. A lower limit may come into force after validation by work on the measurement standard precision.
l. A lower limit of 2,5 mg/kg may come into force after validation work on the measurement standard and on engine oil impacts.
