| Popis: | This report describes the production of ERM-BC700, which is a soya material certified for the mass fraction of selected pesticides. This material was produced following ISO Guide 34:2009 [ ] and is certified in accordance with ISO Guide 35:2006. Soya beans (Glycine max) originating from Uruguay were sprayed with 11 pesticides in solution. The beans were air dried, cryo-milled and homogenised. Between unit-homogeneity was quantified and stability during dispatch and storage were assessed in accordance with ISO Guide 35:2006. 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 / assessment of method performance. As with any reference material, it can be used for establishing control charts or validation studies. The CRM is available in glass vials containing 32 g of cryo-milled soya powder which were sealed under an atmosphere of nitrogen. The minimum amount of sample to be used is 2 g JRC.F.6-Reference Materials |
