Here's the link to the
BQ-9000 Quality Management Program. If you're not going to make your own you may want to think about purchasing Bio Diesel from someone that participates in the program to ensure you're getting the best diesel available.
The National Biodiesel Accreditation Program is a cooperative and
voluntary program for the accreditation of producers and marketers of biodiesel fuel called BQ-9000. The program is a unique combination of the ASTM standard for biodiesel, ASTM D 6751, and a quality systems program that includes storage, sampling, testing, blending, shipping, distribution, and fuel management practices.
BQ-9000 is open to any biodiesel manufacturer, marketer or distributor of biodiesel and biodiesel blends in the United States and Canada.
BQ-9000 - The National Biodiesel Accreditation Program
BQ-9000 helps companies improve their fuel testing and greatly reduce any chance of producing or distributing inadequate fuel. To receive accreditation, companies must pass a rigorous review and inspection of their quality control processes by an independent auditor. This ensures that quality control is fully implemented.
