scope:

This guide explains how to characterize the quality of metal powder feedstock to additive manufacturing (AM) relative to the powder shape using automated static or dynamic image analysis by optical photography. This guide will describe the method(s) to measure powder shape parameters that can identify potentially detrimental powder characteristics and specifically describe how to identify and quantify the proportion of agglomerates/satellites and other irregularly shaped non-spherical powder particles in a powder batch.

The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

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.

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