This European Standard specifies performance requirements and test methods under prescribed
laboratory conditions for a diffusive sampler used for the determination of gases or vapours in workplace
atmospheres. Additional tests designed to establish whether the 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 annexes C and D.
