Biodiesel (fatty acid methyl ester, FAME) is blended into diesel fuels in set proportions, limited by fuel specifications. Per EN 14078, FAME content is determined by measuring the intensity of the characteristic infrared absorption band of the ester group.
Determined
- FAME (biodiesel) content of diesel fuel, % by volume
- Comparison with specification limits (on request)
Reference Standard
- EN 14078 – Liquid petroleum products, determination of fatty acid methyl ester (FAME) content in middle distillates, infrared spectrometry method
Samples
Samples should be sent in clean, sealed glass or suitable plastic containers, protected from light.
