Statistical evaluation of human sensory response to acetone

The release of volatile organic compounds (VOCs) from building products may influence the perceived air quality in the indoor environment. Consequently, building products need to be assessed for chemical emissions and for the acceptability of emitted odours. Recently, the standard ISO 16000-28, which describes the evaluation of perceived odour in test chambers, has been implemented. The procedure requires a panel of trained probands, being calibrated with diluted acetone. However, the calibration procedure itself can be a substantial source of the method uncertainty.
