Beskrivelse

1.1 This practice covers the sampling of workplace atmospheres for the presence of certain gases or vapors by means of diffusion across a specified quiescent region and subsequent sorption on a solid sorbent (1).21.2 A list of organic compounds which are applicable to solid sorbent sampling where the sorbent is contained in a bed through which air is passed is given in Annex A1 of Practice D3686. Diffusive samplers may be applicable to a similar range of compounds but this must be confirmed by reference to the individual sampler manufacturer’s literature.1.3 The valid use of diffusive samplers depends on the existence of actual laboratory or field validation, or both. Guidance on validation can be obtained from published protocols (2-6). This practice is not designed to cover the verification, validation, or specific test procedures used to assess the accuracy or precision of diffusive samplers.1.4 The values stated in SI units are to be regarded as standard. No other units of measure
