EN 13528-1:2002 (E) 4 Introduction This European Standard specifies requirements and test methods for the determination of performance characteristics of diffusive samplers used for the determination of concentrations of gas
20、es and vapours in ambient atmospheres. With regard to air quality, the objectives fixed in the 5th Action Programme of the European Union are for the effective protection of all people against recognised risks from air pollution and the establishment of permitted concentration levels of air pollutan
21、ts, which should take into account the protection of the environment. These objectives include monitoring of concentrations with regard 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
22、 different tools: product standards, emission limits and environmental objectives/standards. The implementation of existing Directives has highlighted the existence of various problems, which are being addressed in the Council Directive on Ambient Air Quality Assessment and Management 1. These inclu
23、de: the different monitoring strategies in comparable situations between and within Member States; the harmonisation of measuring 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
24、some general requirements, which are given in this part of EN 13528. These requirements include unambiguity, selectivity and Data Quality Objectives, including uncertainty. Such general requirements can also be appropriate for other measurement procedures used in the assessment of ambient air qualit
25、y. In addition, diffusive samplers used to measure air quality shall also fulfil some specific requirements in addition to those 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 sampl
26、ers used to measure ambient air quality. It is the users primary responsibility to choose appropriate procedures or devices that 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
27、 assessment of performance criteria of procedures or devices, can be undertaken by the manufacturer, user, test house or research and development laboratory, as is most appropriate. Although this part of EN 13528 specifically addresses ambient air, diffusive sampling is also relevant to the assessme
28、nt of air quality in indoor air. Both pumped and diffusive sampling procedures are considered appropriate for such measurements, depending on circumstances (particularly any requirement for time resolution) 2. prEN 14412 gives guidance on the selection, use and maintenance of diffusive samplers used
29、 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 content 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 Europ
30、ean Directives are different and the consequent definitions and practical applications of the estimation of the uncertainty of measurements are different. EN 13528-1:2002 (E) 5 1 Scope This European Standard specifies general performance requirements for diffusive samplers used for the determination
31、 of the concentration of gases and vapours in ambient air. Such requirements apply to all diffusive samplers, irrespective of 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 stag
32、es of the measuring procedure, including deployment, transportation and storage of the sample where appropriate. This standard applies to measuring procedures with separate sampling and analysis stages, and also to direct- reading devices. 2 Normative references This European Standard incorporates b
33、y dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places 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 Sta

41、nd NOTE 1 The fraction may be viewed as the coverage probability or level of confidence of the interval. NOTE 2 To associate a specific level of confidence with the interval defined by the expanded uncertainty requires explicit of implicit assumptions regarding the probability distribution character
42、ised by the measurement result and its combined standard uncertainty. The level of confidence that can be attributed to the interval can be known only to the extent to which such assumptions may be justified.

NOTE 2 Uncertainty of measurement comprises, in general, many components. Some
47、 of these components may be evaluated from the statistical distribution of the results of a series of measurements and can be characterised by experimental standard EN 13528-1:2002 (E) 7 deviations. The other components, which can also be characterised by standard deviations, are evaluated from assu
48、med probability distributions based on experience or other information. NOTE 3 It is understood that the result of a measurement 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 wi
49、th corrections and reference standards, contribute to this dispersion ENV 13005. Attention is drawn to the fact that the terms Assessment, Limit Value and Pollutant are defined in Directive 96/62/EC 1. 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 1, and successive Daughter Directives, in which the measurement requirements are
