The report discusses the collaborative test, by 10 organizations, of the 'Tentative Method for the Determination of Nitrogen Dioxide in the Atmosphere (Sodium-Arsenite Procedure)' to determine the precision and bias of the method. It covers the NO2, ambient-air sampling system, test site, selection of collaborators, statistical design, collaborators' field sampling, their analysis of samples, statistical analysis of collaborators' results, conclusion and recommendations.
