The work of preparing International Sta

26、ndards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also tak

ISO collaborates closely with theInternational 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 2.The main task of technical committees is to

28、 prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that

34、TE The term “formaldehyde” is used in this International Standard instead of the term “methanal”, as specified byIUPAC regulations.It is intended to be a link between Part 1 of ISO 16000, which describes a measurement strategy, and Parts 3and 4 of ISO 16000, which describe the analytical procedures

35、dealing with active or diffusive sampling of formaldehyde respectively. This part of ISO 16000 presupposes knowledge of Part 1 of ISO 16000.The sampling strategy procedure is based on VDI 4300, Part 31.VOC measurements in different fields of air pollution are described in ISO 16017, Indoor, ambient

37、O 16000 is intended as an aid to planning formaldehyde indoor pollution measurements. In the case of indoor air measurements1), the careful planning of sampling and the entire measurement strategy areof particular significance, since the result of the measurement can have far-reaching consequences,

Details are given in Table B.1.Whereas an intermittent emission source (e.g. the use for a limited period of time of disinfectant spraycontaining formaldehyde) will cause an increased formaldehyde concentration in indoor air for only a shortperiod of time during and after use, a continuo

43、us emission source (e. g. a particleboard used for indoorfurnishings) will contribute to the formaldehyde concentration over a longer period. Figure 1 shows theinfluence of humidity and temperature on the emission rate of formaldehyde from particleboard; by increasinghumidity and temperature, formal

44、dehyde emission increases considerably.1) This part of ISO 16000 uses the definition for indoor environment2, 3defined in ISO 16000-1.

Outdoor air may be contributory only if strong formaldehyde sources (e.g.

49、heavy road traffic) are nearby. In a study of 300 typical households in Germany during 1985/86, the median level of formaldehyde in indoor air was found to be 55 g/m37. In a few per cent of the cases, concentrations were above 100 g/m3. Other, more recent studies in the UK, Sweden and Australia found median formaldehyde concentrations of about 25 g/m3(see Table B.2). Table B.2 compares the median and the range of concentrati
