Specifies performance requirements and test methods under prescribed laboratory conditions for a pumped sorbent tube used in conjunction with an air sampling pump for the determination of gases and vapours in workplace atmospheres. Additional tests designed to establish whether the performance characteristics of the pumped sorbent tube are affected by the wider range of environmental influences that may be encountered in field use are described in annexes. If there is no pumped sorbent tube for measuring a particular chemical agent which meets the requirements of this standard, it is recommended to use a pumped sorbent tube whose performance is nearest to the specified requirements. The standard is applicable to pumped sorbent tubes which are used for the indirect determination of concentrations, by sampling and analysis in separate stages. These tubes can be divided into: - type A samplers which rely on sorption onto a solid or onto a support impregnated with a reagent, desorption with solvent, and subsequent analysis of the desorbate; - type B samplers which rely on sorption onto a solid or onto a support impregnated with a reagent, desorption by heat,and analysis of the desorbate. Specific aspects of the use of reagent impregnated systems will be covered in additional parts of this standard. This standard should enable manufacturers and users of pumped sorbent tubes to adopt a consistent approach to sampler validation and provide a framework for the assessment of sampler performance against criteria specified in EN 482.
