The national approval test for dust respirator certification in Japan requires that air containing quartz particles less than 2 μm in diameter be used as a test aerosol. In view of the international accordance of respirator certification, we developed a new sodium chloride aerosol and oil mist aerosol generator as an alternative. We confirmed that the concentration of generated particles was 33.5 ± 3.4 mg/m<SUP>3</SUP> for the sodium chloride aerosol and 29.8 ± 0.4 mg/m<SUP>3</SUP> for DOP aerosol. Further we measured the size distribution of generated particles using SMPS for 8 hours. Measured count median diameter of generated particles was 0.078 μm for the sodium chloride aerosol and 0.189 μm for DOP aerosol. The geometric standard deviation was 1.773 for the sodium chloride aerosol and 1.581 for DOP aerosol.
