Abstract：Inhalable particulate matter (PM₁₀) sampler is the necessary equipment in dealing with the inspection of PM₁₀ in air, evaluation the air quality, and much relative research work, and the accuracy of such apparatus is a primary character in evaluation the apparatus' metrologi cal performance. Both several methods of inspecting the accuracy of in halable particulate matter sampler and their flaw were introduced and explained, and for the purpose of satisfying the traceability request of metrology, such work as design and investigation of method for accura cy determination of inhalable particulate matter sampler was carried out. This designed method is the calm-air method by determining the filter paper quality, with global particle as reference particle. On this basis, some research work was carried out in this method.
