13th meeting of the CEN/TC 264/WG 2 in Berlin. What happened there?

CEN TC264WG2 meeting BerlinThe 13th CEN meeting of Working Group 2 of the Technical Committee 264 'Air quality - Determination of odour concentration by dynamic olfactometry' took place in Berlin (Germany) at the end of August. The day 28th of August from 09:00 to 17:00 and the 29th from 09:00 to 13:00 a full review of the text was carried out by 19 experts from a few countries in Europe.

 The Bundesanstalt für Materialforschung und -prüfung (BAM) of Berlin was the place selected for the final review of the future EN 13725. After almost 5 years from the first meeting it is time to sum up the work and approve a final document. The ambitious aim set was to approve each and every of the clauses redacted. Was this goal reached?

    Approving clauses resulted to be a very lengthy process. Clause 1 (Scope) and Clause 2 (Normative), were the easy ones. Clause 3 (Terms and definitions) took a bit longer and then things started to get trickier when the group started to discuss the clauses 5.1, 5.2 and 5.3 about odour measurements, odour sampling and determination of odour concentration, respectively. Some modifications were made in each clause, making the procedure of approval lengthier as usual. A few more clauses were approved but it was not possible to reach even half of the document.

  As set in the agenda, the convenor sounded out the attendants about the idea of splitting the standard into two parts: Odour sampling and Odour Concentration Measurement. An informal vote was carried out and the general feeling was that it was a good idea, however it might be a bit late to split the standard at this stage.

   Another interesting discussions happened when the experts were asked about which should be the number of panelists. The EN 13725 standard limits the minimum panel size to not less than four. However, a few studies have shown that a larger panel size will improve repeatability and accuracy of results. No decision has been finally made on this regard at this stage.

   The work could not be finished, so a meeting in Trieste, Italy was arranged for the 22nd and 23rd of February 2018.
