This European Standard specifies a method for the determination of the polyunsaturated (\u2265 4 double bonds) fatty acid (PUFA) methyl esters content of fatty acid methyl ester (FAME) as a whole between 0,6 % (m\/m<\/i>) and 1,5 % (m\/m<\/i>).<\/p>\n

The method covers the predominant four polyunsaturated fatty acid methyl esters of eicosatetraenoic acid (C 20:4 (n-6)), eicosapentaenoic acid (C 20:5 (n-3)), docosapentaenoic acid (C 22:5 (n-3), and docosahexaenoic acid (C 22:6 (n-3)).<\/p>\n

Studies have indicated that based on the linearity of results from this European Standard, PUFA methyl esters can be determined in FAME in the range between 0,3 % (m\/m<\/i>) to 3,0 % (m\/m<\/i>). However, the precision was not established in that range, as no samples within the upper ranges where included in the final interlaboratory test (see 10.1).<\/p>\n

Although the method is applicable to all uses, it is predominantly for FAME for use in diesel engines.<\/p>\n
