BS EN 16179:2012 pdf download – Sludge, treated biowaste and soil — Guidance for sample pretreatment he pretreatment of samples aims at prepatng oe nenreton oSr.T1”Tsample. For determining inorganic chemical and physico-chemical parameters this European Standard describesprocedures (see 10.2) to prepare: test samples for tests under field moist conditions; test samples for testing after drying, crushing, grinding, sieving etc.; test samples of liquid sludge. For determination of organic compounds three pretreatment methods are specified: a pretreatment method if volatile organic compounds are to be measured (see 10.3.2); a pretreatment method if moderately volatile to non-volatile organic compounds are to be measured andthe result of the following analysis will be accurate and reproducible (see 10.3.3); a pretreatment method if moderately volatile to non-volatile organic compounds are to be measured andthe extraction procedure prescribes a field moist sample or if only indicative results are required (see10.3.4). The choice of the method depends above all on the volatility of the analyte. t also depends on the particlesize distribution of the material (see Clause 5 and 8.3), the heterogeneity of the sample and the followinganalytical procedure. 2Normative references The following documents，in whole or in part,are normatively referenced in this document and areindispensable for its application.For dated references, only the edition cited applies.
