25、ment of workplace exposure to chemical and biological agents”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2014 and conflicting national stand

27、 13205-1, CEN/TR 13205-3, EN 13205-4, EN 13205-5 and EN 13205-6 supersedes EN 13205:2001. EN 13205, Workplace exposure Assessment of sampler performance for measurement of airborne particle concentrations, consists of the following parts: Part 1: General requirements; Part 2: Laboratory performance

28、test based on determination of sampling efficiency (the present document); Part 3: Analysis of sampling efficiency data Technical Report; Part 4: Laboratory performance test based on comparison of concentrations; Part 5: Aerosol sampler performance test and sampler comparison carried out at workplac

29、es; Part 6: Transport and handling tests. Significant technical changes from the previous edition, EN 13205:2001: This part of EN 13205 is based on Annex A of the previous edition, EN 13205:2001. The scope has been limited to aerosol samplers, and the current version of the standard is not (directly

30、) applicable to other types of aerosol instruments. As this is now a standard in its own right, a clause on symbols used has been added. Almost all definitions are now given either in EN 1540, Workplace exposure Terminology or in Part 1 of this standard. The method of calculating the uncertainty of

31、a sampler or a measuring procedure has been revised in order to comply with ENV 13005. The concept of “accuracy” is no longer used, instead the concept of “expanded uncertainty” is used. The five major sources of uncertainty due to aspects of the sampling performance of an aerosol sampler (calibrati

32、on of sampler test system, estimation of sampled concentration, bias relative to the sampling convention, individual sampler variability and excursion from nominal flow rate) are described with equations on how to incorporate these uncertainties into the expanded uncertainty of a sampler. CEN/TR 132

33、05-3 gives recommendations how these entities may be calculated from measured sampling efficiency data. The list of the particle size distributions (per sampling convention) to be used for the evaluation of sampler performance has been restricted at the lower end to reflect that particles with an ae

34、rodynamic DIN EN 13205-2:2014-09 EN 13205-2:2014(E)5 diameter less than 0,5 m are not sampled due to aerodynamic forces. In the current version, an additional requirement on the size distributions is that at least 84 % of the aerosol mass consists of particles exceeding 0,5 m. According to the CEN-C

35、ENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary,

36、 Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 13205-2:2014-09 EN 13205-2:2014 (E) 6 Introduction EN 481 defines sampling conventions for the particl

37、e size fractions to be collected from workplace atmospheres in order to assess their impact on human health. Conventions are defined for the inhalable, thoracic and respirable aerosol fractions. These conventions represent target specifications for aerosol samplers, giving the ideal sampling efficie

38、ncy as a function of particle aerodynamic diameter. In general, the sampling efficiency of real aerosol samplers will deviate from the target specification, and the aerosol mass collected will therefore differ from that which an ideal sampler would collect. In addition, the behaviour of real sampler

39、s is influenced by many factors such as external wind speed. In many cases there is an interaction between the influence factors and fraction of the airborne particle size distribution of the environment in which the sampler is used. EN 13205 (all parts) enables manufacturers and users of aerosol sa

40、mplers to adopt a consistent approach to sampler validation, and provide a framework for the assessment of sampler performance with respect to EN 481 and EN 482. It is the responsibility of the manufacturer of aerosol samplers to inform the user of the sampler performance under the laboratory condit

41、ions1)specified in this part of EN 13205. It is the responsibility of the user to ensure the actual conditions of intended use are within what the manufacturer specifies as acceptable conditions according to the performance test. 1) The inhalable convention is undefined for particle sizes in excess

42、of 100 m or for wind speeds greater than 4 m/s. The tests required to assess performance are therefore limited to these conditions. If such large particle sizes or wind speeds actually existed at the time of sampling, it is possible that different samplers meeting this document give different result

43、s. DIN EN 13205-2:2014-09 EN 13205-2:2014 (E) 7 1 Scope This European Standard specifies a laboratory performance test for samplers for the inhalable, thoracic and respirable aerosol fractions, based on determining the sampling efficiency curve of a candidate sampler at a minimum of nine particle si

44、zes. It specifies methods for testing aerosol samplers under prescribed laboratory conditions in order to test whether the performance of a candidate sampler fulfils the requirements of EN 13205-1:2014. This part of EN 13205 is applicable to all samplers used for the health-related sampling of parti
