ASTM D6751-08 details standards and specifications for biodiesels blended with middle distillate fuels. This specification standard specifies various test methods to be used in the determination of certain properties for biodiesel blends. Some of the tests mentioned include flash point and kinematic viscosity.
This is a standard set by the standards organization 'ASTM International'.[1]
ASTM International is one of the largest voluntary standards development organizations in the world. It sets technical standards for materials, products, systems, and services. ASTM International standards have an important role in the information infrastructure that guides design, manufacturing and trade internationally. ASTM International, originally known as the American Society for Testing and Materials (ASTM), was formed over a century ago, when a group of engineers and scientists got together to address frequent rail breaks in the burgeoning railroad industry. Their work led to standardization on the steel used in rail construction, ultimately improving railroad safety for the nation. As the century progressed and new industrial, governmental and environmental developments created new standardization requirements, ASTM responded with consensus standards that have been widely adopted internationally.
In 2008, ASTM published new Biodiesel Blend Specifications.[2]
Biodiesels that conform to specifications for its specific grades in this standard can be run in unmodified diesel engines in the USA and Canada.
It is generally comparable to european standard EN 14214.
