This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 19.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 14331:2024) has been prepared by Technical Committee CEN/TC 19 “Gaseous and
liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat
of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14331:2004.
— modification to include short chain methyl ethers (C6:0 to C14:0);
— deletion of Annex A and Annex B because they have become unnecessary, as reference is made to
EN 14103 for the determination of the pattern of the fatty acid methyl esters by gas chromatography
(GC).
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.

1 Scope
This document specifies a method for the separation of fatty acid methyl esters (FAME) from middle
distillates by liquid chromatography (LC) and for the determination of the pattern of the fatty acid methyl
esters by gas chromatography (GC) according to EN 14103.
The pattern of the fatty acid methyl esters might be used for calculation of the average molecular mass of
FAME according to EN 14078 [1].
Independently from the origin of the middle distillate, this method is applicable to FAME of vegetable or
animal origin that contain fatty acid methyl esters between C6:0 and C24:1. The method is suitable for
the separation and determination of FAME from middle distillates with FAME contents of at least
2 % (V/V
