SPECIFICATION FOR BIODIESEL (B100)

December 2001

Biodiesel is defined as the mono alkyl esters of long chain fatty acids derived from vegetable oils or
animal fats, for use in compression-ignition (diesel) engines. This specification is for pure (100%)
biodiesel prior to use or blending with diesel fuel.#

* To meet special operating conditions, modifications of individual limiting requirements may be agreed upon between purchaser, seller and manufacturer.
** The carbon residue shall be run on the 100% sample.
# A considerable amount of experience exists in the US with a 20% blend of biodiesel with 80% diesel fuel (B20). Although biodiesel (B100) can be used, blends of over 20% biodiesel with diesel fuel should be evaluated on a case-by-case basis until further experience is available.
