ASTM DEVELOPS NEW METHOD FOR TESTING BIOMASS IN FUELS AND FUEL-ASSOCIATED WATER

Historical test methods for detecting microbial contamination in fuels (for example ASTM D6974 ) depended on the ability of microbes to form colonies on specific growth media. These methods were time consuming and typically required a 2-30 day incubation period before final results were obtained. ATP (adenosine triphosphate) is a molecule that is present in all bacteria, fungi, plant and animal cells. Hence, it is an excellent marker for detecting biomass. The test can be performed at the sampling site, and results can be obtained in a matter of minutes. (learn more…)

ASTM DEVELOPS NEW PRACTICE FOR COLLECTING FUEL & FUEL SYSTEM SAMPLES FOR MICROBIOLOGICAL TESTING

For decades, ASTM D 4057 (Practice for Manual Sampling of Petroleum and Petroleum Products) for guidance on how to collect samples. Unfortunately, D 4057 does not provide any infromation specific to collecting samples one which microbiological tests will be performed. In August 2008, ASTM published a new Standard – D 7464 Practice for Manual Sampling of Liquid Fuels, Associated Materials and Fuel System Components for Microbiological Testing.
