(Practice)Standard Practice for Reporting Particle Size Characterization Data
Standard Practice for Reporting Particle Size Characterization Data
SIGNIFICANCE AND USE
3.1 When evaluating the particle size information, if the procedures of the data processing are not available, the user of the data must make assumptions concerning the reported data in the event of analytical inconsistencies. In order for different data sets to be compared it is crucial that the parties report the analytical techniques and methods or procedures for evaluating, calculating, compiling or otherwise processing the data to be reported.
3.2 Particle size characterization information can be reported in three levels of detail in order to satisfy user's needs.
3.2.1 Level 1 applies when only basic information about the material is required, and shall be provided with each shipment. This level represents the minimum information that shall be reported. Level 1 information may be sufficient in such cases as identifying a certain grade of a material or when detailed knowledge of analytical methodology is not needed.
3.2.2 Level 2 presumes the need for knowledge of methodology on the user's part and allows the user to make a more informed judgment about the information provided in Level 1.
3.2.3 Level 3 provides detailed written procedures to allow duplication of the measurement.
3.2.4 Information provided through Levels 2 and 3 will allow users to perform comparative material evaluations among several suppliers, set specifications or define a purchase agreement, perform inter-laboratory studies and most importantly resolve disputes among suppliers and users.
3.3 Reported particle size measurement is a function of both the actual particle dimension and shape factor as well as the particular physical or chemical properties of the particle being measured. Caution is required when comparing data from instruments operating on different physical or chemical parameters or with different particle size measurement ranges. Sample acquisition, handling and preparation can also affect the reported particle size results.
SCOPE
1.1 This practice covers reporting particle size measurement data.
1.2 This practice applies to particle size measurement methods, devices, detail levels, and data formats for dry powders, and wet suspensions of solids, gels, or emulsion droplets. This practice does not pertain to liquid particles. Note 1—For information on reporting liquid particle measurement data, refer to Practice E799.
1.3 This practice does not concern particle concentration information.
1.4 This practice uses SI (Système International) units as standard. State all numerical values in terms of SI units unless specific instrumentation software reports particle size information, including percentiles, indices, and distributions as tabulations and graphs using alternate units. In this case, present both reported and equivalent SI units in the final written report. Refer to Practice E380 for proper usage of SI units.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
Correlation and comparison of particle size measurement data are of general importance to
researchers, processors, suppliers, vendors, and users of particulate materials. Since there are
numerous methods and devices in use, comparisons of size measurement data are subject to perceived
inconsistencies that may be much reduced by the use of standardized reporting.
Data generated by any one size measurement method may be consistent in many respects, yet be
troublesome to correlate due to variances in data processing and reporting formats among equipment
manufacturers. Data generated from methods employing different physical principles present serious
correlation problems due to their sensing of different parameters related to particle size and some
unrelated, such as density, shape and optical properties. Standardized reporting may reduce confusion
resulting from different particle size measurement practices.
