5 h to several hours) sampling of moulds in indoor air by filtration

A description of the factors that hinder this ability

Note: A separate sectional specification covering complex networks will be published as IEC Publication 115-7 (under consideration)

The methods described in this document include sample collection and the preparation of a representative sample based on a sampling plan for the purpose of determining dimensions

Using a concentration versus absorbance curve developed as part of this procedure
