As in previous years, Odournet GmbH offers the Interlaboratory Comparison for Olfactometry in 2015. This ILC will allow your laboratory to confirm compliance to the performance criteria of EN 13725:2003 and is therefore essential for those laboratories that maintain ISO 17025 accreditation.
The ILC will be carried out in June 2015. Registration closes on 28 April 28 2015 and participants can benefit from the early bird registration, which will be open through 31 March 2015.
The 26th of February 2015 a CEN enquiry was finally launched on two projects related with the determination of odours. The Working Group 27 of the Technical Comittee 264 of the European Committee for Standardization (CEN) had the task of developing this Standard and looks like the final draft is ready.
This European Standard will describe two methods for direct assessment of odours in ambient air and will supplement the dynamic olfactometry method described in EN 13725 which is generally only suitable for measurement of odour emissions at the source, as the practical lower detection limit is typically ≥10 ouE/m3 (according to the Final draft) and cannot be applied directly to determine odour exposure in the field.
Dispersion modeling defines the relationship between the emission source and the receptor. While control measures may be applied to the emission source, compliance with odor nuisance standards depend on whether the odor concentrations at the receptor have been adequately reduced with respect to their frequency, intensity, duration and location.
