1 Scope This document specifies a gravimetric method for the determination of the hydrocarbon content in solid waste. It is applicable to hydrocarbon content greater than 0,5 % (m/m) on dry matter basis. This method does not permit to provide qualitative information on the nature and the source of the hydrocarbons. NOTE Aqueous liquid waste samples can be analysed in accordance with prEN ISO 9377-1 or the procedure specified in Annex B. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. prEN 14346, Characterization of waste — Calculation of dry matter by determination of dry residue and water content EN ISO 3696, Water for analytical laboratory use - Specification and test methods (ISO 3696:1987) 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 hydrocarbon content by gravimetry
sum of compounds extractable with acetone/petroleum ether (2+1) which do not adsorb on Florisil and do not evaporate during the drying process. For practical reasons, the term "hydrocarbon content by gravimetry" is abbreviated "hydrocarbon content" in the following text NOTE 1 Substances that comply with this definition are mainly non-polar long-chain or branched aliphatic, alicyclic, polycyclic or alkyl substituted aromatic hydrocarbons.
NOTE 2 This definition differs from that given in EN 14039. 4 Principle Depending on the type of waste, a known amount of the homogenised waste sample is extracted by mechanical shaking twice with acetone/petroleum ether (2+1). The combined extracts are washed twice with water. Polar compounds are removed by chromatography on Florisil. The final extract is evaporated to dryness after which the mass of the residue is determined by weighing. 5 Hazards Acetone and petroleum ether are highly flammable solvents and shall therefore be handled with caution. Special care is required during centrifugation. During extraction substantial pressure can built-up in the extraction vessel. This pressure shall be released by occasional venting of the vessel in a fume hood. Due to its toxicity, the contact with the skin and eyes and the inhalation of petroleum ether vapours shall be avoided. SIST EN 14345:2005

1 Florisil is the trade name of a prepared diatomaceous substance, mainly consisting of anhydrous magnesium silicate. This information is given for the convenience of users of this European Standard and does not constitute an endorsement by CEN of this product. Equivalent products may be used if it can be shown to lead to comparable results. SIST EN 14345:2005

(20 mg for a typical mass of the test portion of 20 g), every step in the procedure shall be checked to find the reason for these high blanks. 10.2 Dry matter Determine the dry matter on a separate sub-sample (or each of the phases when phase separation has taken place) in accordance with prEN 14346. . When stable emulsions exist, the sample shall be analysed without phase separation. 10.3
