in December 1991.

  It was around 24 years ago in Amsterdam. To be precise the 2nd of December, 1991. At the same time that Mikhail Gorbachev was thinking about resigning as President of the Union of Soviet Socialist Republics, a group of enthusiasts met to discuss about the first standard about odour concentration measurement. Today, 33 countries of Europe are using this standard to measure odour concentration. But that was not easy a few years back.

   To start with this history we should go back to 1984.
