Workplace exposure. Procedures for measuring gases and vapours using diffusive samplers. Requirements and test methods Ingestion-build-83346 you can achieve adequate backflow1 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. This
