This report describes the certification of ERM®-CE100, which is a fish (biota) material, for the mass fraction of short-chain chlorinated paraffins (SCCPs) and medium-chain chlorinated paraffins (MCCPs). ERM-CE100 was previously certified for the mass fractions of hexachlorobenzene (HCB) and hexachlorobutadiene (HCBD). This material was produced following ISO 17034:2016 and is certified in accordance with ISO Guide 35:2017. The starting material was wild Wels catfish (Silurus glanis) caught in the area of the Flix reservoir at the Ebro River, Spain. The CRM is available in glass jars with twist-off lids containing at least 40 g of fish paste. Between unit-homogeneity was quantified and stability during dispatch and storage was assessed in accordance with ISO Guide 35:2017. The material was characterised by an interlaboratory comparison of laboratories of demonstrated competence and adhering to ISO/IEC 17025:2017. Uncertainties of the certified values were calculated including 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 for validation studies. Before release of the CRM, the certification project was subjected to peer-review involving both internal and external experts.
