| Popis: | International audience; The objective of this study is to contribute to the future revision of the ISO 22856 standard while comparing the results from different protocols in a wind tunnel. A long duration exposure of collectors using a distribution test bench was compared with the short duration exposure of Petri dishes by using a specific test bench. A wide range of wind speeds up to 7.5 m s-1 were tested depending on the protocol but the most comparable experimental conditions were found at 2 and 4 m s-1, frontal position of the boom at a height of 0.6 m. When normalized according to the sampling surface (groove vs Petri dishes), results were globally comparable from a quantitative point of view. Moreover, the response of the deposition value to a Time of Flight expression was comparable for both exposure protocols and allowed the simulation of the effect of the wind speed. |
