Biofuels

Standards New Zealand is awaiting the outcome from a new work in progress ballot held at the end of last year, on whether the International Organization for Standardization should initiate a new Standard on 'Sustainability criteria for biofuels'. We will be in contact with stakeholders on the outcome once it is announced.

Meanwhile, the American Society for Testing and Materials (ASTM) International has published new and revised Standards for biofuel quality:

  • ASTM D6751-08: Revised to include the requirement of a cold soak filterability test that controls minor compounds and provides a more accurate reading of how the fuel will perform in cold weather conditions
  • ASTM D975-08a: Specification for diesel fuel oils (on-and off-road applications). Revised to allow for up to 5% biodiesel content. This allows B5 blends to be treated the same as conventional diesel for testing purposes.
  • ASTM D396-08b: Specification for fuel oils (home heating and boiler applications). Revised to allow for up to 5% biodiesel content. Like D975, this revision allows B5 blends to be treated the same as conventional fuel oil for testing purposes.
  • ASTM D7467-08: Specification for diesel fuel oil, biodiesel blend (B6 to B20). A newly created Standard governing the properties of blends containing between 6 and 20% biodiesel for on- and off-road applications.

These ASTM Standards can be purchased from Standards New Zealand direct. Please email us at enquiries@standards.co.nz or call 0800 782 632.
