Luftkvalitet

This European Standard specifies performance requirements, validation methods and provides general instructions on the use of diffusive samplers for the determination of the concentration of gases in ambient air.

This standard applies to all stages of the measuring procedure, including preparation, deployment, transportation and storage. It includes general principles applicable to diffusive sampling and analysis. It enables manufacturers and users to adopt a consistent approach to sampler validation and provides a framework for the assessment of sampler performance.

This document specifies general requirements for detection of human pathogenic viruses in bioaerosols in workplace atmospheres (Annex A and Annex B), including sampling strategy, sample transportation and processing and methods of laboratory analysis.

This document is applicable to efficient particulate air filters (EPA), high efficiency particulate air filters (HEPA) and ultra-low penetration air filters (ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical industry. This document establishes a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid (or alternatively a solid) test aerosol and allows a standardized classification of these filters in terms of their efficiency, both local and integral efficiency. This document is based on particle counting methods which actually cover most needs of different applications.
