This document specifies the elimination techniques for removing fine bubbles from fine bubble dispersion in water and how to optimize the elimination procedures to obtain better efficiency.

This document is applicable to fine uncoated bubbles (without shells).

It does not apply to fine coated bubbles (with shells).

NOTE       Fine bubbles dispersed in liquid are classified into “fine bubble with shells” and “fine bubble without shells”. Fine bubble with shells means the fine bubble whose surface/interface is covered almost completely by an object or a collection of objects.

Published By Publication Date Number of Pages
ISO 2021-07 20
]]> This document specifies a test method for the cleaning of hard flooring surfaces. It can be used to demonstrate the comparative cleaning performance of a fine bubble solution to an alternate cleaning solution to remove contaminant from a soiled surface. This alternate cleaning solution can be another fine bubble solution, municipal tap water or a commercially available cleaning solution blended to the manufacturer’s specifications.

This method is not suitable for differentiating between cleaning solutions when the contaminant is excessively applied on the surface as the mechanism of cleaning changes.
