25、 (EN 13205-5:2014) 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 text or

26、 by endorsement, at the latest by December 2014 and conflicting national standards shall be withdrawn at the latest by December 2014.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 responsible

27、 for identifying any or all such patent rights. This document together with EN 13205-1, EN 13205-2, CEN/TR 13205-3, EN 13205-4 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

28、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 performa

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

30、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 used symbols has been added. Almost all definitions are now given either in EN 1540, Workplace exposure Ter

31、minology 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 main part of the standar

32、d states how to determine the performance of an aerosol sampler at a specific workplace. This is an adaption of the laboratory method given in Part 2. The standard gives a method on how to determine the dependence of the sampling efficiency on the collected mass or internally separated mass. The fiv

33、e major sources of uncertainty due to aspects of the sampling performance of an aerosol sampler (calibration of sampler test system, estimation of sampled concentration, bias relative to the sampling DIN EN 13205-5:2014-09 EN 13205-5:2014 (E) 5 convention, individual sampler variability and excursio

34、n from nominal flow rate) are described with formulae on how to incorporate these uncertainties into the expanded uncertainty of a sampler. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard

DIN EN 13205-5:2014-09 EN 13205-5:2014 (E) 6 Introduction EN 481 defines 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 t

37、he inhalable, thoracic and respirable aerosol fractions. These conventions represent target specifications for aerosol samplers, 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 tar

38、get specification, and the aerosol mass collected will therefore differ from that which an ideal sampler would collect. In addition, 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 fract

39、ion of the airborne particle size distribution of the environment in which the sampler is used. The workplace performance test for samplers for the inhalable, thoracic or respirable aerosol fractions described in this document is based on a comparison of concentrations sampled from a specific workpl

40、ace (under otherwise identical conditions) by a candidate sampler and a (previously) validated sampler. Additionally, a method is described for determining a correction factor for recalculation of the concentration determined with one sampler into that of the other at specific workplaces. This metho

41、d is intended for the user, rather than the manufacturer, of aerosol samplers. EN 13205 (all parts) enables manufacturers and users of aerosol 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 E

42、N 482. It is the responsibility of the manufacturer of aerosol samplers to inform the user of the sampler performance under the laboratory conditions1)specified in EN 13205-1. It is the responsibility of the user to ensure that the actual conditions of intended use are within what the manufacturer s

43、pecifies as acceptable conditions according to the performance test. 1) The inhalable convention is undefined for particle sizes 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 si

44、zes or wind speeds actually exist at the time of sampling, it is possible that different samplers meeting this part of EN 13205 give different results. DIN EN 13205-5:2014-09 EN 13205-5:2014 (E) 7 1 Scope This European Standard specifies a method for determining the performance of an aerosol sampler

45、 under prescribed workplace conditions in order to test whether the performance of a candidate sampler fulfils the requirements of EN 13205-1. This part of EN 13205 specifies also a simple method to determine how, for a specific workplace aerosol, the concentration measured by the candidate sampler

46、can be recalculated into that of a validated sampler. This part of EN 13205 is applicable to all samplers used for the health-related sampling of particles in workplace air. Different test procedures and types of evaluation are included to enable application of this part of EN 13205 to a wide variet

47、y of instruments. The methods specified in this part of EN 13205 are not applicable to tests where the performance of personal samplers is related to static samplers or vice versa. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and ar
