EN 13205, Workplace exposure Assessment of sampler performance for measurement of airborne particle concentrations, consists of the following parts: Part 1: General requirem

29、er comparison carried out at workplaces; 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 B of the previous edition, EN 13205:2001. The scope has been limited to aerosol samplers, and the current ver

30、sion 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. All definitions are now given either in EN 1540, Workplace exposure Terminology or in Part 1 or Part 2 of this standard. T

31、he 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 five major sources of uncertainty due to aspects of the sampling

32、performance of an aerosol sampler (calibration 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 e

DINEN 13205-4:2014-09EN 13205-4:2014(E)5 Introduction

35、 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 the inhalable, thoracic and respirable aerosol fractions. These conventions represent target specifications for

36、 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 target specification, and the aerosol mass collected will therefore differ from that which an ideal sampler would

37、 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 fraction of the airborne particle size distribution of the environment in which the sampler is used. The laboratory

38、 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 three laboratory test atmospheres by a candidate sampler and a (previously) validated sampler. EN 13205 (all parts) enables ma

39、nufacturers 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 EN 482. It is the responsibility of the manufacturer of aerosol samplers to inform the user of the sampler perf

40、ormance under the laboratory conditions1)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 manufacturer specifies as acceptable conditions according to the performance test. 1) The inhalable convention is

41、 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 sizes or wind speeds actually exist at the time of sampling, it is possible that different samplers m

42、eeting this part of EN 13205 give different results. DIN EN 13205-4:2014-09 EN 13205-4:2014 (E) 6 1 Scope This European Standard specifies a method for testing aerosol samplers based on comparison of concentrations under prescribed laboratory conditions in order to verify whether the performance of
