This part of the European Standard describes the plume method for determining the extent of recognizable odours from a specific source using direct observation in the field by human panel members under specific meteorological conditions.<\/p>\n
The plume method involves the determination of the presence or absence (YES\/NO) of recognizable odours in and around the plume originating from a specific odorant emission source, for a specific emission situation and under specific meteorological conditions (specific wind direction, wind speed and boundary layer turbulence). The unit of measurement is the presence or absence of recognizable odours at a particular location downwind of a source. The extent of the plume is assessed as the transition of absence to presence of recognizable odour.<\/p>\n
The primary application of this standard is to provide a common basis for the determination of the odour plume extent in the member states of the European Union.<\/p>\n
The results are typically used to determine a plausible extent of potential exposure to recognizable odours, or to estimate the total emission rate based on the plume extent, using reverse dispersion modelling.<\/p>\n
The field of application of this European Standard includes the determination of the extent of the recognizable odour plume downwind from a source, under specific meteorological conditions (e.g. wind direction, wind speed, turbulence, etc. (see 7.3.2<\/span>).<\/p>\n This European Standard does not include:<\/p>\n the measurement of intensity of ambient odours;<\/p>\n<\/li>\n the measurement of hedonic tone of ambient odours;<\/p>\n<\/li>\n the measurement of the odour exposure in ambient air over a longer time period in an assessment area;<\/p>\n<\/li>\n the calculation of estimated source emission rate from plume assessment using reverse dispersion modelling.<\/p>\n<\/li>\n<\/ul>\n An overview of the interaction between existing odour exposure assessment methods is given in Annex A<\/span> including grid method (Part 1), plume method (Part 2) and olfactometry according EN 13725<\/span> <\/span>.<\/p>\n","protected":false},"excerpt":{"rendered":" Ambient air.
