1Summary

One task under the European Mandate M/245 was to investigate the applicability of existing petroleum test method standards for fatty acid methyl esters (FAME). For this task CEN/TC 19 has founded a separate working group 26, which has validated 24 methods via round robins, including the development of new test methods.

The work of CEN/TC 19/WG 26 was aimed at the drafting of amendments for existing ISO standards (with test methods for fossil fuels). These amendments include the extension of the scope of the standards to biodiesel as well as the new precision data for biodiesel. To get these new precision data (repeatability & reproducibility), WG 26 has done a major effort to validate all relevant test methods on request of the Task Force of WG 24 and WG 25 dealing with the specifications.

2Background

CEN has been asked by the Commission (Mandate M/245) to elaborate standards for fatty acid methyl esters (FAME) to be used as sole fuel for heating and diesel engines and as an additive to mineral oil based fuels. This work has been divided amongst two Technical Committees, of which CEN/TC 19 was responsible for determining the applicability of already existing petroleum type test method standards to both pure FAME and to blends. This included comparing precision data, generating new reproducibility and repeatability figures and developing new test method standards if necessary.
