ERM-CA713 was specifically produced to include the four metals cited in the Priority Substances list (Cd, Hg, Ni and Pb) at concentration levels which are targeted to comply with the environmental quality standards (EQSs) referred in Directive 2008/105/EC. ERM-CA713 is a wastewater effluent of mixed domestic and industrial origin. It has been acidified and fortified with As, Cd, Cr, Cu, Hg, Ni, Pb, Se and Zn. This wastewater material will serve as a tailored quality control tool for laboratories involved in the mandatory monitoring of the Priority Substances prescribed under the Water Framework Directive. ERM-CA713 will supplement the series of CRMs for water testing available from the JRC-Institute for Reference Materials and Measurements (IRMM).
ERM-CA713 is primarily intended for method validation (e.g. trueness estimation) and performance controls. It has been prepared and certified in accordance to ISO Guides 34 and 35. Details about material sampling, processing and certification are described in the certification report, which is available together with the certificate in our online catalogue.
