ABSTRACT Twenty years of development of standards for odor concentration measurement in Europe are reviewed. Issues covered are the development of instruments, standards, and guidelines for methodology and calculation of odor concentration as well as validation of results through interlaboratory comparisons. National efforts led to an initiative in the technical committee CEN/TC264 Air Quality of the Committee Europeen de Normalisation (CEN) to draft a European standard. The final draft was validated by an international interlaboratory comparison in 1996. This validation showed that the strict performance criteria set for repeatability, reproducibility, and accuracy (assessed for an n-butanol standard) were attainable by laboratories using two modes of presenting odor samples to assessors (singlestimulus and forced-choice) that were included in the standard. An agreed-upon reference value for the European odor unit was set at 1 ouE/m3≡ 40 ppb/v n-butanol. This value is attained by a strict protocol for pa...
