Explains the grid method for the determination of the level of odour exposure in ambient air. Also provides a set of instructions for measurement of ambient odour exposure within a defined assessment area, using qualified human panel members, over a sufficiently long period of time to be representative for the meteorological conditions of that location, and hence determine the distribution of the frequency of exposure to odours within the assessment area.
