Activities of the french standardisation group (AFNOR) in odours : revision of the standard for the measurement of the odour intensity and creation of a new standard for the area source sampling

Abstract : In the frame of the French regulation evolution and the European standardisation on odour issues, two French technical groups were created 3 years ago. They deal with : - the update of the French standard for the measurement of odour intensity to take account of the publication of the European standardisation (EN 13725); A two-part standard is proposed, the first one dealing with the measurement strategy and the second one defining the application domains of this methodology. - the elaboration of a new standard for the measurement of odour flow rate from area sources by a direct measurement approach, the enclosure approach using an emission flux chamber. Sources to study were classified and strategies measurement were described according to the source dimensions. The current discussions deal with two methods used for passive sources : the "dynamic" one and the "renewing" one. The terminology had been chosen to describe their most influential parameter on the result
