Test methods of measuring particle contamination

According to EN 590, the European standard covering automotive diesel grade (conventional diesel containing up to 7% of fatty acid methyl esters (FAME)), test method EN 12662 on determination of total contamination in middle distillates, diesel fuels and fatty acid methyl esters measures particles in diesel:

The ASTM D 975 standard specification for diesel fuel includes no limit in test method ASTM D 7619 standard test method for sizing and counting particles in light and middle distillate fuels, by automatic particle counter as the measurement is a normal distribution of number of particles versus particle size. The rating procedure describes particle size and related count information. Fuel can therefore be characterize
