Standard Practice for Reporting Particle Size Characterization Data

Importancia y uso:

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.
