What is new in the revised EN13725:2021 standard?

on .

42 003   On the 20th of November 2012 the first meeting took place of Working Group 2, tasked by CEN/TC274 “Air Quality” to revise EN 13725:2003 ‘Air Quality - Determination of odour concentration by dynamic olfactometry’.

   After 8 years of work and 17 meetings, the final draft of the revised standard is finally completed and submitted on May 31st 2021 for formal vote in the CEN Technical Committee 264 “Air Quality” in 2021. This paper lists the changes that will affect the practice of olfactometry in Europe, once this standard is published as EN 13725:2021.

Occupational exposure of olfactometric examiners: possible solutions for the risk assessment

on .

42 003   The aim of this paper is the definition of a new theoretical method for the evaluation of occupational exposure risk for workers involved in dynamic olfactometry. These workers, also called panellists, can be exposed to hazardous pollutants potentially present in odourous mixtures.

   Despite the relevance of this topic, in the regulation and the scientific literature, a standardized method to evaluate the panellists’ occupational is not provided. Therefore, this work aims to suggest practical solutions for the risk assessment of olfactometric workers. The proposed approach is based on the quantification of non-carcinogenic and carcinogenic risk for panellists’, based on the evaluation of hazard indexes (HIs) and the inhalation risks (IRs) for the odorous mixtures.

Field test evaluation of instrumental odour monitoring systems with a novel in-situ calibration approach

   Instrumental Odour Monitoring Systems (IOMS) are employed for continuous objectified technical olfaction. However, the reference for odour perception is the human nose, surpassing technology with outstanding sensitivity and selectivity for many compounds. In order to achieve comparable results, IOMS have to fulfil manifold requirements, resulting in considerable effort in engineering and cost. One-size-fits-all solutions are unlikely to function properly but are nevertheless marketed as the resulting performance is difficult to assess.

   In the course of the publicly funded research project SEPEG (sensor networks for the objective perception of odour sources, BMBF FKZ 01IS17087) all aspects of a complete IOMS solution are scrutinized in their respective context. A main focus of the project is on field test evaluation in real installation situations. Two installation sites have been equipped with networks of real-time IOMS devices.
