Cold Soak Filtration Test Required for Biodiesel Fuels
Posted in Standards, Biodiesel Testing on Nov 24th, 2008
The newest requirement for biodiesel fuel testing is the cold soak filtration test. This was added to the ASTM Method in October 2008, and it is designed to improve purity standards.
In the past, substandard biodiesel would often precipitate material out of solution when exposed to cold temperatures. If this happens with biofuel used in an engine, it can lead to extensive damage. Therefore, legislators required the cold soak filtration test to prevent such substandard product from being available to consumers.
The standards are established by an organization known as the ASTM, American Society for Testing and Materials. For years, the ASTM has set the standards for the fuel source to be allowed in the marketplace.
