B6 to B20 S500 | Biodiesel Blend (B6-B20) Testing According to ASTM D7467-20a

ASTM D7467-20a, Standard Specification for Diesel Fuel Oil, Biodiesel Blend (B6 to B20) defines and provides specifications for B6 to B20 S500 fuel blends.

B6 to B20 S500 fuel blends are low sulfur blends of biodiesel blend stock conforming to ASTM D6751 and light middle or middle distillate fuel diesel fuel with a maximum of 500 ppm sulfur allowed in the final blend.

Paragon is capable of performing a majority of the analysis related to the testing of B6 to B20 S500 fuel blends according to ASTM D7467-20a Table 1 specifications.

Procedures included on our A2LA Scope of Accreditation to ISO/IEC 17025:2005 are designated as such.
