scope:

This European Standard specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of diffusive samplers and of procedures using these samplers for the determination of gases and vapours in workplace atmospheres.
This European Standard is applicable to diffusive samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.
Additional tests designed to establish whether performance characteristics of the diffusive sampler are
affected by the wider range of environmental influences that may be encountered in field use are described in Annex D and Annex E. These Annexes are primarily directed to the users of such devices, who are in the best position to know the specific factors that can significantly affect sampler performance.
