12、bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizat
13、ions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in th
14、e ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of
15、the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 23909 was prepared by Technical Committee ISO/TC 190, Soil qual

BS ISO 23909:2008ISO 23909:2008(E) ISO 2008 All rights reserved vIntroduction The existing International Standards on pretreatment (ISO 11464, ISO 14507 and ISO 16720) are based on a laboratory sample of approximately 1 kg. Such a sa
17、mple is considered representative if the maximum size of the particles is 8 mm (in accordance with Table A.1). The representivity also depends on other factors, like an adequate sampling strategy. The mentioned International Standards describe methods to mix and divide and reduce the particle-size,
18、in order to provide a representative test sample. For volatiles, ISO 14507 provides a procedure for taking a test sample. The other specified pretreatment methods will result in a significant loss of the contaminant. This International Standard connects samples taken in accordance with ISO 10381-8 a
19、nd other methods where large samples are obtained with the International Standards concerning pretreatment ISO 11464, ISO 14507 and ISO 16720. This International Standard is defined for samples up to typically 25 kg, but is basically also applicable to considerably larger samples. BS ISO 23909:2008B

In accordance with ISO 11464 a
21、nd ISO 14507, the following analyses are considered: determination of physico-chemical parameters; determination of moderate volatile organic contaminants; determination of non-volatile contaminants. This International Standard is not applicable when volatile organic compounds have to be analysed. 2
