Air contaminants emitted by furnishing and building materials. Luftororeningar fran inrednings-och byggnadsmaterial.

Describes a climatic chamber used to measure the concentration of formaldehyde and other volatile substances which may be emitted by furnishing and building materials. The equipment consists of 4 climatic chambers of stainless steel, with a volume of 1.00 m3. The chambers are supplied with air at a constant temperature and constant relative humidity by an air handling installation. This installation can supply air within a temperature interval of 17-27 plus or minus 0.5degrees C, and relative humidity between 30-65% plus or minus 2%. The air change rate in each chamber can be regulated between 0.1 and 20 air change rates. This method, which has been designed at the initiative of the Swedish Board of Physical Planning and Building, is associated with standardisation work at present in progress within the European Standardisation Program.
