15、05-1:2014 (E) 3 Foreword This document (EN 13205-1:2014) 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
16、by publication of an identical text or by endorsement, at the latest by December 2014 and conflicting national standards shall be withdrawn at the latest by December 2014.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
17、 CENELEC shall not be held responsible for identifying any or all such patent rights. This document together with EN 13205-2, CEN/TR 13205-3, EN 13205-4, EN 13205-5 and EN 13205-6 will supersede EN 13205:2001. EN 13205, Workplace exposure Assessment of sampler performance for measurement of airborne
18、 particle concentrations, consists of the following parts: Part 1: General requirements (the present document); 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
19、on comparison of concentrations; Part 5: Aerosol sampler performance test and sampler 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 Clauses 1 to 8 of the previous e
20、dition, EN 13205:2001. The scope has been limited to aerosol samplers, and the current version of the standard is not (directly) applicable to other types of aerosol instruments. The list of definitions has been expanded and many definitions are now given in EN 1540, Workplace exposure Terminology.
21、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 “overall uncertainty” is no longer used, instead the concept of “expanded uncertainty” is used. The list of Requirements (Table 1) has been reformulated/
22、changed for some attributes. The current version of the standard envisages two different types of tests: A test of a candidate aerosol sampler and a test of a complete measuring method based on a candidate sampler, respectively. Two flow charts, one for each type of test, have been included to bette
23、r demonstrate the relation between the different parts of EN 13205. Annex A has been added on how to calculate the expanded uncertainty for a measuring procedure based on aerosol sampling but also consisting of several other stages. This is a complete revision and expansion of Annex E in the previou
24、s version. A clause on symbols has been included. 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,

26、m. BS EN 13205-1:2014EN 13205-1:2014 (E) 5 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 the inhalable, thoracic and respirable aerosol fractions
27、. 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 target specification, and the aerosol mass collected will
28、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 fraction of the airborne particle size distribution of the e
29、nvironment in which the sampler is used. EN 482 contains general performance requirements for methods used for determining the concentrations of chemical agents in workplace atmospheres. These performance requirements include maximum values of expanded uncertainty (a combination of random and non-ra
30、ndom measurement uncertainty) achievable under prescribed laboratory conditions for the methods to be used. The requirements of EN 482 apply to a complete measuring procedure, a combination of the stages consisting of sampling, sample transport/storage and sample preparation/analysis. This part of E
31、N 13205 gives performance requirements for samplers for the inhalable, thoracic or respirable aerosol fractions. Requirements for the aerosol sampler and transport of loaded collection samplers are stated. Furthermore, the method for calculating the expanded uncertainty for a measuring procedure bas
32、ed on aerosol sampling is described. Different test procedures and types of evaluation are described in the other parts of EN 13205 in order to enable application of EN 13205 to a wide variety of instruments. In detail, three different performance tests for sampled concentration and a transport test
33、 of loaded collection substrates are described. The three tests differ in the amount of information obtained by the test and its corresponding cost. The first test method determines the sampling efficiency curve of a candidate sampler, the second compares concentrations sampled from three laboratory
34、 test atmospheres by a candidate sampler and a (previously) validated sampler, and the third method compares concentrations sampled from a specific workplace by a candidate sampler and a (previously) validated sampler. Additionally a method for determining equivalence between aerosol samplers at spe
35、cific workplaces and an alternative handling test are presented. 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 EN 482. It is t
36、he responsibility of the manufacturer of aerosol samplers to inform the user of the sampler performance under the laboratory conditions1)specified in other parts of this European Standard. It is the responsibility of the user to ensure that the actual conditions of intended use are within what the m
37、anufacturer specifies 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 larg
38、e particle sizes 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. BS EN 13205-1:2014EN 13205-1:2014 (E) 6 1 Scope This European Standard specifies performance requirements that are specific to aerosol
39、samplers, primarily inhalable, thoracic and respirable aerosol samplers. These performance requirements, which include conformity with the EN 481 sampling conventions, are applicable only to the process of sampling the airborne particles from the air, not to the process of analysing particles collec
40、ted by the process of sampling. Although analysis of samples collected in the course of testing is usually necessary in order to evaluate the sampler performance, the specified test methods ensure that analytical errors are kept very low during testing and do not contribute significantly to the end
41、result. This part of EN 13205 specifies how the performance of aerosol measuring procedures is assessed with respect to the general requirements of EN 482, through the combination of errors arising in the sampling, sample transportation/storage and sample preparation/analysis stages. This part of EN
42、 13205 is applicable to all samplers used for the health-related sampling of particles in workplace air. This part of EN 13205 is not applicable to the determination of analytical errors and factors related to them (for example the bias, precision and limit of detection of the analytical method). Wh
43、ere the aerosol sampler requires the use of an external (rather than integral) pump, the pump is not subject to the requirements of this part of EN 13205. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its ap
