Abstract

This report describes the production of the reference material BCR-162R, certified for its fatty acid profile. It contains all the required steps that ensure the high quality of the final product, from the processing to the value assignment, such as the homogeneity and stability studies, according to ISO Guide 34 [1]. The matrix material, a soya-maize oil blend, is packed in amber glass ampoules containing approximately 5.5 g of the oil blend and kept at a temperature of -20 Degree Celsius. Studies performed at IRMM confirmed homogeneity and stability of the fatty acids in the oil matrix under the evaluated conditions. The characterisation of the material, organised and coordinated by IRMM, was done by an interlaboratory comparison. The certified values were obtained as the unweighted mean of the laboratory means of the accepted sets of results for each analyte, and the expanded uncertainty associated (k = 2) includes contributions from the characterisation, the homogeneity and the stability.
