2 1. Source and Preparation of Material The starting material for preparing CRM BAM-U110 was an alluvial soil from an area periodically exposed to floods of river Saale. The site is located near the city of Halle (Saxony-Anhalt, Germany) and contaminated by pollutants of industrial and municipal origin. The soil was collected from a depth between 0.2 and 0.8 m; according to sieve analysis the matrial was classified as silty clay loam. The raw material was dried in a convection oven at 30 C to constant mass and then passed over a vibrating 2 mm screen discarding the fraction > 2 mm. The material passing the screen was ground in a ball mill (with grinding bowls and balls made of agate) completely to particle sizes below 63 µm. Homogenisation and bottling of the ground material was performed using a tilted drum mixer equipped with a gravimetrically controlled filling device. The overall number of bottled units was 600, with (60 ± 1) g of soil each. 2. Matrix Composition Determination of main matrix constituents of the bottled reference material performed at BAM by X-ray fluorescence analysis gave the following results: Element Si Al Ca Fe K S Mg Mass Fraction (%) The given values for these non-certified total mass fractions are in good agreement with results submitted by some of the participants in the interlaboratory comparison (see Annex). Further analytical results characterising the sample matrix: Parameter Mass Fraction in % Analytical Method Dry Matter Content at 105 C 97.3 ISO Loss on Ignition at 550 C 13.3 DIN Organic Carbon 6.7 ISO Inorganic Carbon 0.8 ISO Carbon (total mass fraction) 7.5 Automatic CHN-Analyzer Hydrogen 1.2 Automatic CHN-Analyzer Nitrogen 0.4 Automatic CHN-Analyzer ph values in water and CaCl 2 solution (according to ISO 10390): 7.4 and 7.2, respectively. 3. Homogeneity Test The homogeneity of the CRM was tested with respect to certified aqua regia extractable mass fractions of elements only, because for total mass fractions even a better degree of homegeneity can be expexted in any case. For analysis a subset of 12 bottled units was selected in a systematic scheme following the sequence of bottling. From each of these units 4 sub-samples of approximately 500 mg each were taken and extracted with aqua regia according to ISO Analyses of extracts were carried out under repeatability conditions by ICP OES and AAS. The element specific standard uncertainties u hom, reflecting a possible heterogeneity of the bottled samples and being a component of the combined uncertainties u cert, were calculated in accordance with the statistical approaches given in ISO Guide 35 (Reference materials General and statistical principles for certification). For total mass fractions of elements the same relative quantities of u hom (expressed in %) were taken into account as for aqua regia extractable mass fractions. 4. Stability Test For stability testing of the CRM selected bottles were stored at different temperatures (-20 C, +22 C and +40 C) and analysed after 7, 14 and 24 months. As in the case of homogeneity testing, analyses were restricted to aqua regia extractable mass fractions of elements, because instabilities with respect to total mass fractions had to be expected with minimum probability. The analytical data obtained by ICP OES and AAS were evaluated referring the results for samples which were exposed to elevated temperatures to the results for samples stored at -20 C (assuming these samples to be stable). On the basis of these results no significant changes of the CRM during the test period could be detected. Further stability monitoring will be performed at intervals of three CRM BAM-U110 page 2 of 4

3 years. If there will be any evidence of deterioration of the material, all known users of the CRM will be informed by BAM. 5. Certification CRM BAM-U110 was certified by means of an interlaboratory comparison organised by BAM. The total number of participating laboratories was 49, all of them with proven competence in soil analysis. All calculations were performed in accordance with ISO Guide 35. Individual data sets were rejected only in the case that they were identified as outlying laboratory means by Nalimov-test with a level of statistical confidence of 99%. Accepted laboratory means and used analytical methods are given in the annex to this certificate. Besides the results for cerified parameters this annex also contains results for mass fractions of additional elements submitted by some of the participating laboratories. These results are given as indicative values if there were three or more data sets available, and as informative values in the case of less than three data sets. It is stressed that these values are not certified and that they are given for information purposes only. 6.

Recommendations for Correct Use and Storage The CRM BAM-U110 is available as a powder with particle sizes below 63 µm and is supplied in 100 ml brown glass bottles containing (60 ± 1) g. The material is intended for the verification of analytical results obtained by standardised procedures as well as for the validation of modified or new analytical procedures. Furthermore, it can be used for quality control or calibration purposes if X-ray fluorescence spectrometry or other methods of direct solid state analysis are applied. The certified values are valid for a minimum sample intake per analysis of at least 500 mg. The expiry date is three years after the date of shipment provided the sample will be stored at a temperature below 30 C in a dust-free and dry environment avoiding any kind of contamination. The validity of certified values may be extended as further evidence of stability becomes available. The material should be used as it is from the bottle. However, before taking a sub-sample from it a rehomogenisation by manual shaking of the closed bottle is strongly recommended. The bottle shall be left unclosed as shortly as possible. When extracting the sample with aqua regia the analytical protocol prescribed by ISO must strictly be followed. All analytical results have to be corrected for dry matter content of the material which should be determined according to ISO using a separate sub-sample.
