ASTM ethanol fuel testing.
Intertek tests fuel grade ethanol to ASTM standards. Ethanol testing laboratories also provide sampling and ethanol cargo inspection services. Ethanol testing and inspection services are available in the USA, Brazil, Europe, Australia, and other locations. Ethanol fuel test methods include standardized testing methods from the NBR (Brazilian Association of Technical Standards) and ASTM (American Society for Testing and Materials). 
Intertek ethanol testing labs analyze ethanol content and impurities testing by methods for required for fuel grade ethanol. Fuel grade denatured ethanol testing is provided on a global basis. Additional biofuel testing includes fusel oils, esters, and methanol content.
