The report concerns the collaborative test, by 10 collaborators, of the 'Tentative Method for the Determination of Nitrogen Dioxide in the Atmosphere (Continuous-colorimetric method)' to determine the precision and bias of the method. The report covers the NO2, ambient-air sampling system, test site, selection of collaborators, statistical design, collaborators field sampling, statistical analysis of collaborators' results, conclusions and recommendations.
