Scope

This document specifies the evaluation method for size and concentration indices of ultrafine bubbles(UFBs) in water including the data correction to exclude the influence of particulate contaminants using the blank water. Furthermore, the procedure to prepare the blank water is described.

It is only applicable to ultrafine bubble dispersion (UFBD) in water.
