18、Horizontal standards in the fields of sludge, biowaste and soil”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2013, and conflicting national s

19、tandards shall be withdrawn at the latest by February 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been pre

20、pared under a mandate given to CEN by the European Commission and the European Free Trade Association. The preparation of this document by CEN is based on a mandate by the European Commission (Mandate M/330), which assigned the development of standards on sampling and analytical methods for hygienic

21、 and biological parameters as well as inorganic and organic determinants, aiming to make these standards applicable to sludge, treated biowaste and soil as far as this is technically feasible. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following co

22、untries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

23、Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 16179:2012EN 16179:2012 (E) 5 Introduction This document has been developed upon existing International Standards for the pretreatment of soils of specified particle fractions. Historicall

24、y this has been the case for analysing organic compounds after pretreatment according to e.g. ISO 14507. Standards describing pretreatment for chemical and physico-chemical parameters, e.g. ISO 11464, historically have divided the samples into fractions 2 mm where the fraction 2 mm and the extraneou

25、s material removed from the sample the results also can be calculated referring to the mass of the whole sample. The report shall clearly state to which fraction the results refer. BS EN 16179:2012EN 16179:2012 (E) 10 Beside the requirements given in this European Standard, the subsequently applied

26、analytical standards shall be regarded for particular requirements to be observed. The determination of some parameters requires sample pretreatment soon after sampling as specified in the respective analytical methods. If several parameters are being investigated, the sample pretreatment shall be d

27、esigned so that the parameters of major importance are determining the pretreatment. If this is not possible, e.g. the required precision for each parameter can not be achieved, separate pretreatment shall be set up for each group of parameters. Whenever volatile compounds are to be determined, the

28、process of sample pretreatment can result in a substantial loss of these compounds. Sample pretreatment shall be omitted in these cases by taking specific samples for the determination of volatile components. These samples shall be pretreated in accordance with the appropriate analytical standard an

29、d analysed as soon as possible after sampling. When preparing composite samples the analytical requirements shall be considered. For example, composite samples are not appropriate if volatile compounds are to be determined. Figure 1, Figure 2 and Figure 3 show flow charts for: pretreatment for inorg

30、anic and physico-chemical parameters in solid sludge, treated biowaste and soil (Figure 1), pretreatment for organic parameters in solid sludge, treated biowaste and soil (Figure 2), pretreatment for inorganic, physico-chemical and organic parameters in liquid sludge (Figure 3). Aside from the param

31、eter to be determined, the procedure to be applied also depends on the required minimum mass of the sample to be used in relation to the maximum particle size D95of the sample. For this the relationship described in ISO 10381-8 is used (see Table 2 in 8.3). Grinding of the sample depends on the mass

32、 of the subsample being taken. Table 1 gives the requirements for a wide group of parameters. For some parameters the requirements stated in 8.3 need not to be followed exactly as the homogeneity of the samples is enough to obtain adequate results for those parameters.

42、8512 for preservation and storage of soil samples, EN ISO 5667-13 for guidance on sampling of sludge samples and EN ISO 5667-15 for preservation and storage of sludge samples. Treat biowaste samples the same as soil samples regarding storage. 5.3 Pretreatment in the field When possible, the sample p

43、retreatment should take place in the laboratory, as sample integrity can be best guaranteed under laboratory conditions. Subsampling by the methods given in 8.4.2 can be performed in the field as well as in the laboratory. In the field, sample pretreatment is restricted to the process of subsampling

44、 by sample division. Pretreatment is necessary if field samples are too large to be transported to the laboratory, or if the amount of material sampled is larger than the amount of material necessary for the test or analysis. When subsampling is necessary, the relation between the minimum mass of th

45、e subsamples and the maximum size of the particles (D95) in the original field sample shall be taken into account (see 8.3). Samples are divided into subsamples either mechanically or manually. Subsampling methods are described in 8.4.2. In some cases the soil is strongly aggregated. Such macro aggr

46、egates can be reduced by hand (see 8.4.1) otherwise they should be seen as individual “particles“.
