Standard Practice for Calibration and Verification of Direct Imaging Analyzers Used for Particle Size and Shape Analysis of Catalytic Materials

Importancia y uso:

5.1 Particle size and shape are important in predicting the performance of catalytic materials. They influence the bulk density of the final product and thereby the effectiveness of performance.

5.2 Establishing a verification reference for the analyzer that is commercially available and dimensionally reliable to close tolerances enables different analyzers to be easily checked to equivalent standards.

5.3 This practice may also be followed to analyze catalytic materials for quality manufacturing purposes. Sections 9 and 10 instruct on sample count determination as well as sampling recommendations. Test Method D6299 may be utilized to monitor performance of the analyzer in measuring the size and shape of catalytic materials.
