摘要：

ASTM International Committee D02 on Petroleum Products and Lubricants and Subcommittee D02.E0 on Burner, Diesel, Non-Aviation Gas Turbine, and Marine Fuels are producing new and improved standards for biodiesel and blended biodiesel fuels. The only ASTM International standard that exists for biodiesel is D 6751, Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels. An important feature for this specification is that it is not a fuel specification but is for a fuel blend stock that can be used at up to 20 volume percent. D 6751 places limits on impurities that can remain from the biodiesel production process to protect the performance and durability of combustion equipment, which include methanol, glycerin, and unconverted and partly converted feedstock. Subcommittee D02.E0 is also working on a separate specification for biodiesel blends with concentrations between 6% (B6) and 20% (B20).
