IP 440 Part 2: Determination of total contamination – Part 2: Fatty acid methyl esters

Overview:

In the previous version of this method, the scope was covering middle distillates, diesel fuels containing up to 30 % (V/V) of FAME and neat FAME. It was found that the improvement sought in 2014, give problems in the lab in testing FAME and correlate the results to those obtained with the previous version of the method. A solution has been found, which resulted in splitting the methodology in two parts: to include the previous version as Part 1 and to develop a separate standard for neat FAME as Part 2.
