(FR) PROCEDE ET DISPOSITIF DE DETERMINATION DU COEFFICIENT ET DU POTENTIEL D'EMISSION DE PARTICULES D'UN MATERIAU, ET PROCEDE DE GESTION D'UNE VOIE DE CIRCULATION
Method for determining the particle emission coefficient of a material (CE), comprising the steps of: b) successively, for different masses of fines: b1) disposing a mass of said fines in a chamber (10); b2) and, by injecting air into the chamber (10), ejecting the particles from the chamber in an outgoing air flow; b3) measuring the maximum mass concentration (PM_max) of the particles in the outgoing air flow and the total ejection time (D_Ej) of the particles; d) calculating a trend line (D) that is representative of the function providing the maximum standardised particle concentration (PM_max_norm) as a function of the standardised ejection time (D_Ej_norm) of the particles; e) calculating the particle emission coefficient of the material (CE) according to the slope of the trend line (D).
