This Eur
13、opean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2011, and conflicting national standards shall be withdrawn at the latest by October 2011. Attention is drawn to the possibility that some of the el
14、ements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14103:2003. The main modifications of the standard are intended: - to enlarge the scope of the method to FAME from
15、animal fat, by changing the internal standard (FAME C19 instead of FAME C17); - to verify the purity of the internal standard as it was proven that some lots may have a purity not good enough; - to improve the precision data by modifying the preparation of the test portion. According to the CEN/CENE
16、LEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuani

BS EN 14103:2011EN 14103:2011 (E) 4 1 Scope The purpose of this document is to describe a procedure for the determination of the ester content in fatty acid methyl
18、 esters (FAME) intended for incorporation into diesel oil. It also allows determining the linolenic acid methyl ester content. It allows verifying that the ester content of FAME is greater than 90 % (m/m) and that the linolenic acid content is between 1 % (m/m) and 15 % (m/m). This method is suitabl
19、e for FAME which contains methyl esters between C6 and C24. NOTE For the purposes of this European Standard, the terms “% (m/m)” and “%(v/v)” are used to represent respectively the mass and volume fractions. WARNING The use of this method may involve hazardous equipment, materials and operations. Th
20、is method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Principle Determination of t
21、he percentage of total methyl esters of fatty acids and the percentage of linolenic acid methyl ester present in the sample, by gas chromatography according to a procedure using internal calibration (nonadecanoic acid methyl ester). 3 Reagents Use only reagents of recognized analytical grade, unless
22、 otherwise specified. 3.1 Toluene, analytical grade. 3.2 Nonadecanoic acid methyl ester (FAME C19), purity, min. 99,5 % (m/m)1). NOTE Standard should be kept in a dry storage in order to limit its water absorption. Its water content should be verified by Karl-Fischer when a new lot of standard is op
23、en. 3.3 Carrier gas, hydrogen or helium. 3.4 Auxiliary gases: air; hydrogen. 4 Apparatus Usual laboratory apparatus and, in particular, the following. 1) Nonadecanoic FAME with acceptable quality is available from Fluka - Ref: 74208 () or from Nu Chek Prep - Ref: N-19-M (www.nu-) or Dr. Ehrenstorfer
