3、eral importance toresearchers,processors,suppliers,vendors,and users of particulate materials.Since there arenumerous methods and devices in use,comparisons of size measurement data are subject to perceivedinconsistencies that may be much reduced by the use of standardized reporting.Data generated b
4、y any one size measurement method may be consistent in many respects,yet betroublesome to correlate due to variances in data processing and reporting formats among equipmentmanufacturers.Data generated from methods employing different physical principles present seriouscorrelation problems due to th
5、eir sensing of different parameters related to particle size and someunrelated,such as density,shape and optical properties.Standardized reporting may reduce confusionresulting from different particle size measurement practices.1.Scope1.1 This practice covers reporting particle size measurementdata.
6、1.2 This practice applies to particle size measurementmethods,devices,detail levels,and data formats for drypowders,and wet suspensions of solids,gels,or emulsiondroplets.This practice does not pertain to liquid particles.NOTE1For information on reporting liquid particle measurementdata,refer to Pra
