21、would affect the results.Sample pretreatment is to preferably take place in the laboratory, as sample integrity can be best controlled under laboratory conditions. However, under some circumstances, pretreatment may be started in the field directly after sampling, to obtain a representative laborato
22、ry sample from the material extracted from the ground, or to prepare a composite laboratory sample.The representativeness of a sample depends on factors like sample size, particle size, particle shape, contaminant type and concentration, consistence of soil materials and sampling strategy (see ISO 1
23、8400-1041).When volatiles are present, the procedures described in ISO 22155 are to be used as appropriate if possible. No further pretreatment is allowed. Other specified pretreatment methods will result in a significant loss of volatiles.Pretreatment comprises one or a combination of the following
24、: homogenization; sample division: obtaining subsamples of smaller size than the original sample without reducing the particle size of the individual particles; particle size reduction: grinding and crushing the sample in order to reduce the particle size of the sample without reducing the sample si
25、ze (mass); separation of fractions on the basis of particle sizes (sieving or screening) if only a separate size fraction of soil is of interest for investigation or on the basis of the physical nature of the materials (e.g. appearance); preparation of composite sample(s).Several cycles of a number
26、of these activities could be required to derive the test sample (e.g. analytical sample) from the material extracted from the ground. Except as noted above when pretreatment would affect the results of subsequent testing or analysis, subsampling is normally required in the laboratory because the amo
27、unt of material in the laboratory sample (i.e. that sent from the field to the laboratory) is almost always larger than the amount of material necessary for the test or analysis.There might be occasions when it is considered desirable to combine soil material in the field from, for example different
28、 locations into a composite sample. A suitable procedure for doing this is described in this document.For reasons explained in Clause 4, only some of the pretreatment measures listed above can be carried out in the field.This document is part of a series of sampling standards for soil. The role/posi

However, under some circumstances, as described in this
48、document, some pretreatment can be done in the field to reduce the size of a large field sample to a more manageable size for sending to the laboratory or to select a particular fraction to form the laboratory sample.The direct selection of the material to form the laboratory sample from the materia
49、l extracted from the ground when this forms an integral part of the sampling process is described in ISO 18400-102 on the selection and application of sampling techniques.When the laboratory sample is received, pretreatment is usually required before testing to determine chemical or other properties, although there are some situations when any pretreatment would be unacceptable because it would affect the results (e.g. when volatile organic compounds are present).
