Abstract: This report describes the production of ERM®-EF003, which is an automotive diesel fuel material containing a volume fraction of 7 % fatty acid methyl ester (biodiesel) certified for the volume fraction of the fatty acid methyl ester content, the mass fraction of mono-aromatic hydrocarbon, di-aromatic hydrocarbon, polycyclic aromatic hydrocarbon, and total aromatic hydrocarbon content, and density, kinematic viscosity, and lubricity. This material was produced following ISO Guide 34:2009 [ ] and is certified in accordance with ISO Guide 35:2006 [2]. The material is an automotive diesel fuel containing a volume fraction of approximately 7 % biodiesel that is based on rapeseed oil fatty acid methyl ester with the addition of 1 g/kg antioxidant (butylhydroxytoluene). It was provided by a producer in Germany. The material was filled in amber glass ampoules. Between unit-homogeneity was quantified and stability during dispatch and storage were assessed in accordance with ISO Guide 35:2006 [ ]. The minimum sample intake is the required sample volume stipulated in the respective documentary standard. The material was characterised by an interlaboratory comparison of laboratories of demonstrated competence and adhering to ISO/IEC 17025:2005 [ ]. Technically invalid results were removed but no outlier was eliminated on statistical grounds only. Uncertainties of the certified values were calculated in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM) [ ] and include uncertainties related to possible inhomogeneity, instability and characterisation. The material is intended for quality control and assessment of method performance. As with any reference material, it can be used for establishing control charts or validation studies. The certified reference material (CRM) is available in amber glass ampoules containing 27 mL of automotive diesel fuel material with a volume fraction of 7 % biodiesel closed under argon atmosphere.
