3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/ASTM 52900 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
3.1
cohesiveness
physical powder behaviour relating to the degree to which the attractive forces between particles exceed the average particle mass
Note 1 to entry: Cohesive powders are qualified as powders where the attractive force between particles exceed the average particle mass
3.2
powder flowability
ability of a solid bulk material to flow
Note 1 to entry: Powder flowability is a function of multiple factors, and particularly powder size and distribution, see also ISO/ASTM 52907.
