Fine bubble technology — General principles for usage and measurement of fine bubbles — Part 5: Shelled bubble vocabulary

This document specifies the general principles of the definition of bubbles with shells, including the gas-filled structures/particles dispersed in liquids. The shell cited in this document is one created deliberately in manufacturing. Shells created by naturally occurring layers created on the surface of bubbles due to adhesion of bubbles are out of the scope of this document.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International E
