BS ISO 21910-1:2020

This standard BS ISO 21910-1:2020 Fine bubble technology. Characterization of microbubbles is classified in these ICS categories:

• 07.030 Physics. Chemistry

This document specifies the evaluation method for the size index of microbubbles in microbubble dispersion. It is only applicable to microbubbles with or without shell in water within the range from 1 ?m to 100 ?m. It describes the sampling methods from the point generating or dispersing microbubbles in the retention container to the detecting point of the measuring instruments.
