10、SO 15009:2002(E) iv ISO 2002 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each
11、member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
12、 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards
13、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 the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be t

16、 International Standard specifies a method for quantitative gas-chromatographic determination of volatile hydrocarbons, naphthalene and volatile halogenated hydrocarbons in soil. This International Standard is applicable to all types of soil. Under the conditions specified in this International Stan
17、dard, the following limits of determinations apply (expressed on basis of dry matter): volatile hydrocarbons and naphthalene: 0,1 mg/kg; volatile halogenated hydrocarbons: 0,01 mg/kg. The lower limit of determination is dependent on the equipment used and the quality of the methanol grade used for t
18、he extraction of the soil sample. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not

However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members

The test sample is extracted with methanol. After centrifugation, part of the methanol extract is brought i

The adsorbed compounds are desorbed thermally and, by means of a carrier gas flow, optionally via a cold trap, brought into a gas chromatograph. The various com

Volatile aromatic hydrocarbons are detected with a flame ionization detector (FID). Volatile halogenated hydrocarbons are detected with an electron capture det

Part of the effluent is brought to the FID and part to the ECD, e.g. via an effluent splitter. Identification and quantification takes place by comparison of retention
