DESCRIPTION

BS EN 14412:2004


This standard BS EN 14412:2004 Indoor air quality. Diffusive samplers the determination of concentrations of gases and vapours. Guide for selection, use and maintenance is classified in these ICS categories:
  • 13.040.20 Ambient atmospheres
This document gives guidelines for the selection, use and maintenance of diffusive samplers used to analyse gaseous pollutants in indoor air including measurement strategy and planning. This document gives guidelines for the selection, use and maintenance of diffusive samplers used to measure indoor air quality and personal exposure. This document is applicable to indoor air quality assessment because crucial differences to ambient air measurement have to be taken into account concerning environmental parameters, measurement strategy, as well as the nature, number, source and abundance of indoor air pollutants. In contrast to typical ambient air measurements the appearance of unexpected compounds in indoor air environments is quite common. Procedures to calculate specific uptake rates of these compounds are needed more often as there is only a limited number of uptake rates validated by experiments (see EN 13528-2 and EN 13528-3) to assess the respective concentration values. In addition to the general calculation procedure of the individual uptake rate as given in EN 13528-2 and EN 13528 3 detailed procedures to calculate diffusion coefficients and the uptake rate are given in annex C of this document.
