18、 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 member body interested in a subject for which a technical committe

19、e 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 Electrotechnical Commission (IEC) on all matters of electrotechni

20、cal standardization. International Standards are drafted in accordance with the rules 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 b

21、odies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

30、EN ISO 16000-5:2007vi Introduction In ISO 16000-1, general requirements relating to the measurement of indoor air pollutants and the important conditions to be observed before or during the sampling of individual pollutants or groups of pollutants are described. This part of ISO 16000 describes basi

31、c aspects to be considered when working out a sampling strategy for the measurements of volatile organic compounds (VOCs) in indoor air. It is intended to be a link between ISO 16000-1, Indoor air, General aspects of sampling strategy, the analytical procedures described in ISO 16000-6, Indoor air,

This part of ISO 16000

34、presupposes knowledge of ISO 16000-1. The sampling strategy procedure described in this part of ISO 16000 is based on Guideline VDI 4300 Part 61. EN ISO 16000-5:20071Indoor air Part 5: Sampling strategy for volatile organic compounds (VOCs) 1 Scope This part of ISO 16000 is intended as an aid to pla

35、nning volatile organic compound (VOC) indoor pollution measurements. In the case of indoor air measurements, the careful planning of sampling and the entire measurement strategy are of particular significance since the result of the measurement may have far-reaching consequences, for example, with r

36、egard to the need for remedial action or the success of such an action. An inappropriate measurement strategy may contribute to the complete uncertainty of the measurement result in a larger extent than the measurement procedure itself. This part of ISO 16000 uses the definition for indoor environme

This classification, based primarily on the boiling point, t

44、akes into account aspects of the analysis, especially gas chromatography. Since the transition points are fluid here, it is not useful to specify sharp limits for the boiling point ranges and the sampling media to be selected. NOTE 1 Boiling points of some compounds are difficult or impossible to de

45、termine because they decompose before they boil at atmospheric pressure. Vapour pressure is another criterion for classification of compound volatility that may be used for classification of organic chemicals3. NOTE 2 TVOC (total volatile organic compounds) is defined in ISO 16000-6. 4 Sources and o

46、ccurrence Several hundred VOCs have been detected in indoor air, stemming from various sources. These sources may be present in the room continuously or intermittently. The most important continuous sources are all kinds of building products, furniture, and room textiles. Intermittent sources includ

47、e household products and products for renovation, as well as the occupants and a number of their activities, such as smoking and hobby work. Ambient air shall also be considered as a source although its contribution to indoor air pollution by VOCs is generally less important. The various types of so

48、urces mentioned in the preceding paragraph emit a wide range of different VOCs into the indoor air. They also have different emission profiles. As the goal of most indoor air analyses is to provide as representative information as possible on the air pollution status of a room, taking into account t

49、he emission characteristics, it is important to develop a sound measurement strategy. In addition, it shall be considered that VOC concentrations in indoor air vary from room to room and are also subject to change over time. It is difficult to establish a comprehensive list of which VOCs are emitted from which sources because of the ongoing variation in the production of products and the resulting change in the composition of the mixture of VOCs emitted. The VOCs
