New Biodiesel Specs
ASTM International has released a new standard for biodiesel that will help ensure that biodiesel blends of up to 20 percent will be compatible with future diesel exhaust emissions technology.
A release from the National Biodiesel Board says the new standard, D 6751-06a, adds new limits on calcium and magnesium, which can be introduced during the biodiesel manufacturing process.
According to Steve Howell, National Biodiesel Board Technical Director and Chairman of the ASTM Task Force on biodiesel standards, “Engine manufacturers were concerned that even very small amounts of minor compounds could build up in particulate traps and eventually cause the traps to clog,” said Howell. “The new ASTM specification addresses these concerns and demonstrates the industry’s eagerness to work with manufacturers to ensure compatibility between the equipment and the fuel.”
