Utomhusluft - Diffusionsprovtagare för koncentrationsbestämning av gaser och ångor - Krav och provningsmetoder - Del 3: Vägledning för urval, användning och underhåll
This part of the European Standard gives guidance on the selection, use and maintenance of diffusive samplers used to measure ambient air quality. It includes guidance on measurement objectives and strategies, both in support of European Community Policy and more generally, relevant to the use of such samplers. It also includes information on the operating principles of diffusive samplers and the factors that affect performance in the practical implementation of such policies. Advice is also given on ways to minimise any such adverse effects, e.g. by suggesting shelters that may protect against the effects of wind speed on the samplers, and on training and quality assurance considerations.
Annexes give further information on practical applications for particular environmental pollutants, including those specified by existing and anticipated European Daughter Directives.
