Standard Test Method for Determination of Contamination Level of Fatty Acid Methyl Esters in Middle Distillate and Residual Fuels Using Flow Analysis by Fourier Transform Infrared Spectroscopy—Rapid Screening Method

Importancia y uso:

5.1 The present and growing international governmental requirements to add Fatty Acid Methyl Esters (FAME) to diesel fuel has had the unintended side-effect of leading to potential FAME contamination of fuels in multi-fuel transport facilities such as cargo tankers and pipelines, and industry wide concerns. This has led to a requirement to measure contamination levels in diesel and other fuels to assist custody transfer issues.

5.2 Analytical methods have been developed with the capability of measuring down to <5 mg/kg levels of FAME in aviation turbine fuel (AVTUR), however these are complex, and require specialized personnel and laboratory facilities. This Rapid Screening method has been developed for use in the supply chain by non-specialized personnel to cover the range of 20 mg/kg to 500 000 mg/kg (0.002 % to 50 %).

5.3 A similar procedure, Test Method D7797, is available for AVTUR in the range 10 mg/kg to 150 mg/kg. Test Method D7797 uses the same apparatus, with a specific model developed for AVTUR.
