22、ument (EN 13205-6:2014) has been prepared by Technical Committee CEN/TC 137 “Assessment 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 te

23、xt or by endorsement, at the latest by December 2014 and conflicting national standards shall be withdrawn at the latest by December 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held respon

EN 13205, Workplace exposure Assessment of sampler performance for measurement of airborne particle concentrations, consists of

25、 the following parts: Part 1: General requirements; Part 2: Laboratory performance test based on determination of sampling efficiency; Part 3: Analysis of sampling efficiency data Technical Report; Part 4: Laboratory performance test based on comparison of concentrations; Part 5: Aerosol sampler per

26、formance test and sampler comparison carried out at workplaces; Part 6: Transport and handling tests (the present document). Significant technical changes from the previous edition, EN 13205:2001: This part of EN 13205 is partly based on Annex D of the previous edition, EN 13205:2001. The scope has

27、been limited to aerosol samplers, and the current version of the standard is not (directly) applicable to other types of aerosol instruments. As this is now a standard in its own right, a clause on the used symbols has been added. Almost all definitions are now given either in EN 1540, Workplace exp

28、osure Terminology or in Part 1 of this standard. The method of calculating the uncertainty of 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 standard gives t

29、wo methods to determine the dependence of the mass loss from collection substrates due to transport and/or handling, respectively. It is described how to use the test data to calculate the uncertainty due to transport/handling and how this is related to the requirements given in Part 1 of this Europ

30、ean Standard. According to the CEN-CENELEC 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 Macedoni

DIN EN 13205-6:2014-09 EN 13205-6:2014 (E) 4 Introduction EN 481 defines

32、sampling conventions for the particle 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 sampler

33、s, giving the ideal sampling efficiency 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 add

34、ition, the behaviour of real samplers 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. This part of EN 13205 describe

35、s two test methods for determining the uncertainties due to transport errors. The values calculated can directly be compared to the requirements of EN 13205-1:2014 The first method is based on loading collection substrates with particles from a workplace aerosol and delivery by ordinary mail. The se

36、cond method is based on loading collection substrates with particles from a specified laboratory test aerosol and subsequent exposure of the collection substrates to vibrations using either a laboratory shaker table or a vertical shaker. EN 13205 (all parts) enables manufacturers and users of aeroso

37、l samplers 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 co

38、nditions1)specified in this part of EN 13205. It is the responsibility of the user to ensure that the actual conditions of intended use are within what the manufacturers specifies as acceptable conditions according to the performance test. 1) The inhalable convention is undefined for particle sizes

39、in excess of 100 m or for wind speeds greater than 4 m/s. The tests required to assess performance are therefore limited to these conditions. Should such large particle sizes or wind speeds actually exist at the time of sampling, it is possible that different samplers meeting this standard give diff

40、erent results. DIN EN 13205-6:2014-09 EN 13205-6:2014 (E) 5 1 Scope This European Standard specifies a performance test of loaded collection substrates for samplers for the inhalable, thoracic or respirable aerosol fractions and, as alternative, a handling test, both for testing transport losses of

41、aerosol sampler substrates under prescribed conditions in order to calculate the expanded uncertainty of a measuring procedure according to EN 13205-1:2014, Annex A. The transport test involves shipping loaded substrates with ordinary mail, whereas the handling test uses a shaker. This part of EN 13

42、205 applies to all samplers used for the health-related sampling of particles in workplace air. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
