14、 standards 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. Internationa

15、l organizations, 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

16、given in the 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 lea

30、ment of indoor air pollutants and the important conditions to be observed before or during the sampling of individual pollutants or groups of pollutants. Aspects of the determination (sampling and analysis) and the sampling strategy of specific pollutants or groups of pollutants are specified in the

31、 subsequent parts of ISO 16000 (see Foreword). ISO 16000-5 (dealing with VOC sampling strategy) is a link between ISO 16000-1 (a generic standard establishing the principles) and this part of ISO 16000, which deals with sampling and analytical measurements. ISO 16017 (see Clause 2 and Reference 8) a

33、hermal desorption and gas chromatography using MS or MS-FID 1 Scope This part of ISO 16000 specifies a method for determination of volatile organic compounds (VOCs) in indoor air and in air sampled for the determination of the emission of VOCs from building products or materials and other products u

34、sed in indoor environments using test chambers and test cells. The method uses Tenax TA1)sorbent with subsequent thermal desorption (TD) and gas chromatographic (GC) analysis13employing a capillary column or columns and a flame ionization detector (FID) and/or a mass spectrometric (MS) detector. The

35、 method is applicable to the measurement of non-polar and slightly polar VOCs at concentrations ranging from sub-micrograms per cubic metre to several milligrams per cubic metre. Using the principles specified in this method, some very volatile compounds (VVOC) and semi-volatile organic compounds (S

36、VOC) can also be analysed (see Annex D). 2 Normative references The following referenced documents are indispensable for the application of this document.

45、, detected with a flame ionization detector (TVOC-FID) or mass spectrometric detector (TVOC-MS), and quantified by converting the total area of the chromatogram in that analytical window to a nominal mass using the chromatographic response factor for toluene (toluene equivalents) NOTE While this par

46、t of ISO 16000 specifies the determination of individual VOCs, it is common in practice to generate a single concentration value to characterize the total amount of VOCs present in the air. This value is called the TVOC value (see 11.3 and Clause 13). It should be emphasized that the TVOC value so o

47、btained depends on the sampling and analytical methods used, and therefore should be interpreted taking into account the full description of these methods. 4 Principle A measured volume of sample air is collected from room air, an emission test chamber (see ISO 16000-9) or an emission test cell (see

48、 ISO 16000-10) by drawing through one (or more) sorbent tube containing Tenax TAsorbent. Volatile organic compounds (VOCs) are retained by the sorbent tube, and the compounds are subsequently analysed in the laboratory. The collected VOCs are desorbed by heat and transferred under inert carrier gas

49、via a cold trap or sorbent trap into a gas chromatograph equipped with a capillary column or columns and a flame ionization detector and/or a mass spectrometric detector. 5 Reagents and materials 5.1 Volatile organic compounds for calibration, of chromatographic quality. 5.2 Dilution solvent, for preparing calibration blend solution for liquid spiking, of chromatographic quality, free from compounds co-eluting
