This European Standard is a multi-part standard having the following parts: - Part 1 (Ambient Air Quality) General

17、 requirements; - Part 2 (Ambient Air Quality) Specific requirements and test methods; - Part 3 (Ambient Air Quality) Guide to selection, use and maintenance. Annex A is informative.

19、ard specifies requirements and test methods for the determination of performance characteristics of diffusive samplers used for the determination of concentrations of gases and vapours in ambient atmospheres. With regard to air quality, the objectives fixed in the 5hAction Programme of the European

20、Union are for the effective protection of all people against recognised risks from air pollution and the establishment of permitted concentration levels of air pollutants, which should take into account the protection of the environment. These objectives include monitoring of concentrations with reg

21、ard to standards. Successive programmes of action of the European Union on the protection of the environment have stressed the need to find a balance between the use of different tools: product standards, emission limits and environmental objectives/standards. The implementation of existing Directiv

22、es has highlighted the existence of various problems, which are being addressed in the Council Directive on Ambient Air Quality Assessment and Management I. These include: - the different monitoring strategies in comparable situations between and within Member States; - the harmonisation of measurin

23、g methods; - the quality of the measurements which depends on the calibration and quality assurance procedures. Diffusive samplers used to measure air quality have to fulfil some general requirements, which are given in this part of EN 13528. These requirements include unambiguity, selectivity and D

24、ata Quality Objectives, including uncertainty. Such general requirements can also be appropriate for other measurement procedures used in the assessment of ambient air quality. In addition, diffusive samplers used to measure air quality shall also fulfil some specific requirements in addition to tho

25、se specified in this part of EN 13528. These specific requirements are given in EN 13528-2. EN 13528-3 gives guidance on the selection, use and maintenance of diffusive samplers used to measure ambient air quality. It is the users primary responsibility to choose appropriate procedures or devices th

26、at meet the requirements in this European Standard. One way of doing this is to obtain information or confirmation from the manufacturer. Type testing, or more generally, the assessment of performance criteria of procedures or devices, can be undertaken by the manufacturer, user, test house or resea

27、rch and development laboratory, as is most appropriate. Although this part of EN 13528 specifically addresses ambient air, diffusive sampling is also relevant to the assessment of air quality in indoor air. Both pumped and diffusive sampling procedures are considered appropriate for such measurement

28、s, depending on circumstances (particularly any requirement for time resolution) 2. prEN 14412 gives guidance on the selection, use and maintenance of diffusive samplers used to measure indoor air quality. This part of EN 13528 is similar in content to EN 482:1994 and EN 13528-2 is similar in conten

29、t to EN 838:1995.The series of standards on the use of diffusive samplers for ambient air has been created in addition to those for workplace air because the underlying European Directives are different and the consequent definitions and practical applications of the estimation of the uncertainty of

30、 measurements are different. 4 EN 13528-Ir2002 (E) 1 Scope This European Standard specifies general performance requirements for diffusive samplers used for the determination of the concentration of gases and vapours in ambient air. Such requirements apply to all diffusive samplers, irrespective of

31、the physical nature of the rate controlling process and irrespective of the nature of the sorption process and the analytical determination. This standard applies to all stages of the measuring procedure, including deployment, transportation and storage of the sample where appropriate. This standard

32、 applies to measuring procedures with separate sampling and analysis stages, and also to direct- reading devices. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate plac

33、es in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

39、ugh a membrane, but which does not involve the active movement of air through the device NOTE 1 Active normally refers to the pumped movement of air. NOTE 2 This definition differs from that in EN 838:1995 by the addition of the words or a porous material, 3.7 expanded uncertainty quantity defining

40、an interval about the result of a measurement that may be expected to encompass a large fraction of the distribution of values that could reasonably be attributed to the measurand NOTE 1 The fraction may be viewed as the coverage probability or level of confidence of the interval. NOTE 2 To associat

41、e a specific level of confidence with the interval defined by the expanded uncertainty requires explicit of implicit assumptions regarding the probability distribution characterised by the measurement result and its combined standard uncertainty. The level of confidence that can be attributed to the

42、 interval can be known only to the extent to which such assumptions may be justified. NOTE 3 Expanded uncertainty is temed overall uncertainyin ENV 13005.

Same of these components may be evaluated from the statistical distribution of the results of a series of measurements and c

The other components, which can also be characterised by standard deviations, are evaluated from assumed probability distributions based on experience or other information. NOTE 3 It is understood that the result of a meas

48、urement is the best estimate of the value of a measurand, and that all components of uncertainty, including those arising from systematic effects, such as components associated with corrections and reference standards, contribute to this dispersion ENV 130051. Attention is drawn to the fact that the

49、 terms Assessment, Limit Value and Pollutant are defined in Directive 96/62/EC I. 4 Assessment regimes Different regimes of air quality assessment are possible for the implementation of the Council Directive on Ambient Air Quality Assessment and Management I 1, and successive Daughter Directives, in which the measurement requirements are relaxed as the risk of exceeding the limit values decreases (see annex A). Other assessment regimes may be required by a number of other EU regulations (Acidification Directive, Directive on Forest Protection) as we
