21、f 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 committee has been established has the right to be represented on that committee. In

22、ternational 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

23、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 bodies for voting. Publication as an International Standard requires approval

24、 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

31、nd/or complex symptoms in humans. Moreover, mould growth can be associated with severe odour nuisances. Inrare cases, some mould species can cause infections (so-called mycoses) in certain risk groups.141819There is sufficient epidemiological evidence that damp and mouldy buildings increase the risk

32、 of respiratory symptoms, respiratory infections and enhances asthma symptoms of the occupants.8In addition, there is some evidence for increased risk of development of allergic rhinitis and asthma. Furthermore, there is clinical evidence for rare symptoms like allergic alveolitis, chronic rhinosinu

33、sitis and allergic sinusitis. Toxicological studies in vivo and in vitro show irritating and toxic reactions of microorganisms (including spores, cell components and metabolites) from damp buildings.8Growth of microorganisms in damp buildings can lead to increased concentrations of spores, cell frag

34、ments, allergens, mycotoxins, endotoxins, -glucanes and MVOC (microbial volatile organic compounds). From the studies conducted so far it is not clear which compounds are the causative agents of the health effects observed. Nevertheless, increased concentrations of each of these compounds are consid

35、ered a potential health risk818and growth of mould in buildings should, therefore, be avoided. The prime objective of this part of ISO 16000 is to provide assistance in identifying mould sources in indoor environments.

It describes suitable sampling and analysis methods together with a descriptio

37、n of the applicability and the interpretation of the measurement results to maximize the comparability of the measured data obtained for a given measurement objective. It does not include details on recording building characteristics or field inspections by qualified professionals which have to take

38、 place prior to any microbiological measurement. This part of ISO 16000 is not applicable to a detailed description of the building physics- and building-engineering-related procedures applicable to field inspections. The methods and procedures presented do not allow quantitative exposure assessment

43、on efficiency considers the sampling stress occurring during sampling and analysis in addition to the physical collection efficiency. 3.3 identification of moulds assignment of moulds to spore types or groups on the basis of defined properties (e.g. morphological, biochemical, molecular-biological p

44、roperties) NOTE The term “differentiation” is frequently used instead of identification. The term “differentiation” is, however, misleading because the intention is not to merely differentiate the moulds but to identify them, i.e. to assign them, e.g. to genera or species. 3.4 filamentous fungus fun

45、gus growing in the form of filaments of cells known as hyphae NOTE 1 Hyphae aggregated in bundles are called mycelia. NOTE 2 The term “filamentous fungi” differentiates fungi with hyphal growth from yeasts. 3.5 filtration collection of particles suspended in a gas or liquid by flow through a porous

46、medium SOURCE: EN 13098:20006 NOTE In this part of ISO 16000, filtration is understood as the separation of microorganisms or moulds from a defined volume of air by means of filters. 3.6 total spore count number of (culturable and non-culturable) spores that are collected and enumerated under the mi

47、croscope NOTE For the term “spores”, see 3.19, Note 2. 3.7 yeast unicellular fungus that does not normally produce a mycelium and reproduce by budding (budding fungi) as against moulds, which reproduce by sporulation 3.8 impaction sampling of particles suspended in air by inertial separation on a so

48、lid surface (culture medium or adhesive-coated slides) NOTE 1 See 16000-18. NOTE 2 Sampling is carried out using either round-hole or slit impactors, for instance. As the air passes through the orifices, it is accelerated and the particles are impacted on the medium located directly behind the nozzl

49、es as a result of their inertia, while the air flows around the culture medium and exits the sampler. Impaction samples are only suitable for direct analysis without further resuspension of the sample. 3.9 colony forming unit cfu air quality unit by which the culturable number of microorganisms is expressed SOURCE: EN 13098:20006 NOTE 1 One colony can originate from one single microorganism, from aggregates of many microorganisms as well as from one or many microorganisms attached
