适用范围：This European Standard specifies specific performance requirements and test methods under prescribedlaboratory and field conditions for diffusive samplers used for the determination of the concentration of gases orvapours in ambient air.Such requirements apply to all diffusive samplers, irrespective of the physical nature of the rate-controlling processand irrespective of the nature of the sorption process and the analytical determination.This standard applies to all stages of the measuring procedure, including transportation and storage of the samplewhere appropriate.This standard applies to measuring procedures with separate sampling and analysis stages, and also to directreadingdevices.This European Standard is applicable to diffusive samplers according to 3.6 of EN 13528-1:2002.This European Standard should enable manufacturers and users of diffusive samplers to adopt a consistentapproach to sampler validation and provide a framework for the assessment of sampler performance againstcriteria specified in EN 13528-1. It is the responsibility of the manufacturer or of those who assemble the diffusivesamplers to ensure that the sampler complies with the data quality objectives given in this European Standard.For the purpose of demonstrating compliance with data quality objectives prescribed for methods to be used insupport of the Council Directive on Ambient Air Quality Assessment and Management, this part of EN 13528provides the relevant requirements and test methods for the determination of measurement uncertainty. Asindicated in 6.5.2 to 6.5.4, some of these procedures are to be undertaken by a single representative laboratory,some by several laboratories in an interlaboratory trial, and some by the laboratory implementing the method. Thisdivision of responsibility is in accordance with Table 1 of CEN Report CR 14377:2002 [3].Where only one laboratory is involved in establishing the performance characteristics of a method, as in amanufacturer’s assessment, the reproducibility elements of the uncertainty budget shall be estimated under withinlaboratoryreproducibility conditions, i.e. by performing the relevant experiments independently, as far asreasonably practicable. This type of assessment is identified as level 2 (see clause 8).This standard can encourage the development of new types of diffusive sampler. Prior to conducting a fullevaluation according to this standard, it would be useful to conduct laboratory or field intercomparisons withestablished samplers. These intercomparisons should be conducted by experienced institutes.
