Truck biodiesel

Eurofins is an industry leader in the testing and analysis of biodiesel and other alternative fuels. Approved by the National Biodiesel Board, we offer a complete line of laboratory tests specifically designed to enable producers, blenders, distributors and end–users to meet the industry standards set forth in ASTM D6751, ASTM D975, and the BQ–9000 accreditation program.

Eurofins was a pioneer in designing comprehensive testing programs to support ASTM D6751. We have the technical expertise, practical experience, and state–of–the–art technology to handle all of your biodiesel testing needs. We know the special needs of our customers at every link in the biodiesel supply chain –– producers, blenders, distributors, and end–users –– and our testing packages are custom–made to address each one them.

PRODUCER PACKAGES - TESTING B100 BY ASTM D6751

The standard specification for biodiesel fuel blend stock (B100) is ASTM D6751. This specification is comprised of 15 tests. These tests define the required properties of biodiesel fuel at the time and place of delivery.

Eurofins ANA Laboratories offers two testing packages to enable biodiesel producers to show that their product meets these industry standards.

PREMIUM PRODUCER PACKAGE

Our premium package is designed to ensure strict compliance with ASTM D6751. Strict compliance is achieved by performing all 15 tests exactly as specified. This package also enables producers to evaluate their product for sale or use.

Biodiesel Blend Packages - Testing B1-B20 By EMA Specifications

The de facto standard specification for biodiesel/petrodiesel blends was developed by the Engine Manufacturers Association (EMA) in May 2006 to identify a standard blend fuel with consistent properties suitable for use in testing and evaluation. The EMA defines blend fuel is defined as a blend of: (1) petroleum diesel fuel meeting ASTM D975, and (2) biodiesel fuel (B100) meeting either ASTM D6751 or EN14214, where the biodiesel content of the blended fuel is no more than 20% biodiesel by volume (B20).

This specification is comprised of 19 tests. These tests define the required properties of biodiesel fuel at the time and place of delivery.

Eurofins offers two testing packages to enable biodiesel blenders, distributors and users to show that their product meets these industry standards.

Premium Biodiesel Blend Package

Our premium package is designed to ensure strict compliance with the EMA specifications. Strict compliance is achieved by performing all 19 tests exactly as specified. This package also enables blenders, distributors and users to evaluate their product for sale or use.
