This paper describes the effect of allowance for basic specifications of single particle counters on its counting results. Even particle counters meet requirement of Japanese Industrial Standard JIS-B-9921 (Light Scattering Automatic Particle Counter), they may show more than 40% differences in counting results. And we found that size resolution which is not specified in JIS-9921 is also important factor to get more accurate data from comparison test.
