This report describes the production of the ERM-BB125, which is an egg material certified for the mass fraction of fipronil sulfone and the sum of fipronil and fipronil sulfone expressed as fipronil. This material was produced following ISO 17034 and is certified in accordance with ISO Guide 35. Eggs from a farm embargoed by the Belgian food safety authorities were freeze-dried, cryo-milled and homogenised. Between-unit homogeneity was quantified and stability during dispatch and storage were assessed in accordance with ISO Guide 35. The material was characterised by an interlaboratory comparison of laboratories of demonstrated competence and adhering to ISO/IEC 17025. 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 the quality control and assessment of method performance. As with any reference material, it can be used for establishing control charts or during validation studies. The CRM is available in sealed glass vials containing at least 5 g of dried egg powder. The minimum amount of sample to be used is 1 g of the dry material.
