34、ampling of individual pollutants or groups of pollutants are described.This part of ISO 16000 describes basic aspects to be considered when working out a sampling strategy for the measurements of carbon dioxide in indoor air. It is intended to be a link between ISO 16000-1 and the analytical procedu
35、res.This part of ISO 16000 presupposes knowledge of ISO 16000-1.This part of ISO 16000 uses the definition for indoor environment defined in ISO 16000-1 and Reference 12 as dwellings having living rooms, bedrooms, DIY (do-it-yourself) rooms, recreation rooms and cellars, kitchens and bathrooms; work
36、rooms or work places in buildings which are not subject to health and safety inspections with regard to air pollutants (for example, offices, sales premises); public buildings (for example hospitals, schools, kindergartens, sports halls, libraries, restaurants and bars, theatres, cinemas and other f
37、unction rooms), and also cabins of vehicles and public transport.The sampling strategy procedure described in this part of ISO 16000 is based on VDI 4300 Part 9.11vi ISO 2012 All rights reservedBS EN ISO 16000-26:2012INTERNATIONAL STANDARD ISO 16000-26:2012(E)Indoor air Part 26: Sampling strategy fo
38、r carbon dioxide (CO2)1 ScopeThis part of ISO 16000 specifies the planning of carbon dioxide 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
39、can have far-reaching consequences, for example, with regard to ascertaining the need for remedial action or the success of such an action.An inappropriate measurement strategy can lead to misrepresentation of the true conditions or, worse, to erroneous results.This part of ISO 16000 is not applicab
40、le to the measurement strategy for carbon monoxide (CO).NOTE See 5.1.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced doc
41、ument (including any amendments) applies.ISO 16000-1:2004, Indoor air Part 1: General aspects of sampling strategy3 Properties, origin and occurrence of carbon dioxideCarbon dioxide (CO2, CAS No. 124-38-9) is a natural constituent of atmospheric air, where it is present on average at a content of a
42、little over 0,03 % (volume fraction; equal to about 600 mg/m3). CO2content measured in air is usually reported in the unit parts per million (1 ppm as a volume fraction is 1 mol/mol), 0,03 % as volume fraction being equivalent to 300 ppm. Some CO2reacts under indoor conditions with atmospheric humid
43、ity to form carbonic acid. CO2is colourless, odourless and without taste, readily water soluble and chemically stable under standard conditions. The CO2molecule can absorb part of the infrared radiation reflected by the Earths surface as heat radiation and thus contributes to a process termed “green
44、house effect”, which causes global warming.Carbon dioxide plays a central role in the processes of life on Earth. As a result of plant activity (from carbon dioxide and water, under the action of sunlight in the presence of chlorophyll as catalyst), organic compounds (predominantly carbohydrates) ar
45、e formed, as well as the oxygen which is essential for life on Earth. More or less in reverse to this process, CO2is formed in the air as one of the end-products (in addition to water) of combustion of hydrocarbons. This process proceeds firstly in every type of combustion apparatus and fireplace, b
46、ut secondly also plays an important role in the metabolism of living organisms. The CO2formed in metabolic processes is released to the ambient air.In the case of humans, the amount released depends on the extent of physical activity. For adult persons, the orders of magnitude listed in Table A.1 of
47、 the volume of CO2released can be assumed (see Annex A for more detailed explanations).Since the beginning of industrialization, the CO2concentration of the ambient air has been continuously rising. CO2measurement sites in the past were usually linked with meteorological stations and were situated i
48、n clean air regions. One of the best-known CO2measurement sites is on Mauna Loa in Hawaii. There, uninfluenced by any local CO2source, the CO2concentration increased, for example, from 316,0 ppm in 1959 to 369,4 ppm in ISO 2012 All rights reserved 1BS EN ISO 16000-26:2012ISO 16000-26:2012(E)2000 (Re
49、ference 13). This is an increase of 53,4 ppm or 4,1 per year. Since CO2is a climatically relevant substance (greenhouse effect), the increase is being observed with great concern. In the vicinity of emissions sources, e.g. metropolitan areas with heavy vehicle traffic and domestic fires or industrial combustion plants, significantly higher concentrations can also occur. Thus the CO2concentration in Cologne with approx. 400 ppm is on average about 10 % higher than in Hawaii (see Figure 1)
