ASTM E3338 : 22

1.1 This guide provides information for determining particle size and shape using Dynamic Imaging Analyzers (DIA) in multiple application points including in-line, at-line and stand alone, lab based or portable, configurations. This guide focuses on concepts and strategies for applying imaging techniques to process applications in a way that improves the knowledge of the particles contained in dynamic flows, dry and wet, which can lead to more improved control of manufacturing processes.

1.2 Analyzers may be configured for open, dry or wet analysis, or enclosed, dry or wet analysis, as appropriate for analysis of the process or test specimen. Particles in liquid borne flows can be analyzed at least up to 1000 µm and dry particle flows can be analyzed up to several cm if equipment is appropriate for the size. Limitations will be discussed in Section 6.

1.3 The values stated in SI units are to be regarded as 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International StandardDetails, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
