Starting material for the preparation of the certified reference material ERM®-CC018 was a sandy soil collected from a stockpile excavated during a remediation campaign on an industrial wasteland in the Berlin region (Germany).
The material was certified on the basis of analytical results obtained in several BAM working groups according to the principles laid down in ISO Guide 35:2006 and in the technical guidelines of the European Reference Materials® co-operation agreement between BAM, IRMM, and LGC.
Certified values are given for aqua regia extractable (ISO 11466) mass fractions of As, Cd, Co, Cr, Cu, Hg, Ni, Pb, V and Zn. The CRM is available as a powder with particle sizes below 63 µm and is intended for the verification of analytical results obtained by standardised procedures as well as for the validation of modified or new analytical procedures.
