Conclusions:
According to ISO 13320:2009, the cumulative distribution of Everzol SR98 are d(0.10)=23.4μm, d(0.50)=49.1μm and d(0.90)=94.8μm, and the average particle size in surface area and volume of Everzol SR98 are 41.3μm and 54.8μm, separately.
Executive summary:

This test using the procedures outlined in the ZRICI Study Plan for PCF2019-045-09 andISO 13320:2009.The obscuration value is out of 0.5%~6%, conforms to the requirement for testing.The determination result can be considered valid.Cumulative distribution of Everzol SR98 are d(0.10)=23.4μm, d(0.50)=49.1μmand d(0.90)=94.8μm. Average particle size in surface area and volume of Everzol SR98 are 41.3μm and 54.8μm, separately.
