ASTM WK25737

    New Guide for Correlation of Results of Particle Size Measurement Instruments

    (What is a Work Item?)

    Developed by Subcommittee: E29.02 | Committee E29 | Contact Staff Manager


    1. Scope

    1.1 1.1 This guide describes one methodology to correlate particle analysis results between particle analysis instruments for user specified products of user specified particle sizes and distributions in order to expand the capability of particle measurement throughout the manufacturing process and provide better control and efficiency. The guide is not limited to instrument type or product type. 1.2 All instruments may not correlate to all other instruments for various user specified products and size ranges. Instruments may measure different particle features, and they may also measure the same particle features differently and thus correlating the results of any two may be possible for some products but not possible for others. It is also the case that certain materials can be altered by the instruments measuring them which would eliminate them from consideration under this guide if the instruments results are determined based on measurements made after the instrument has altered the user specified product. 1.3 Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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.
