TS ISO 20480-1

TS ISO 20480-1 is a terminology standard for fine bubble technology, setting out the terms and definitions used in this field. Fine bubbles refer to very small gas bubbles introduced into liquids, where they can influence mass transfer, interfacial behavior, and fluid dynamics. This part establishes the shared language for the area and helps users interpret usage, measurement, and application terms consistently.

Why terminology matters in this field

The main value of a terminology standard is consistency. In fine bubble technology, the same concept may be discussed in engineering, water treatment, process development, or laboratory contexts, and unclear wording can make comparisons difficult. Terms such as bubble size, concentration, distribution, and lifetime are often central to technical discussion, so defining them in one place supports clearer reporting and more reliable communication across teams and applications.

What this part covers

• General terms and definitions for fine bubble technology
• Vocabulary related to usage of fine bubbles
• Concepts used in measurement and evaluation
• Terms used across individual application areas

In general technical context, fine bubbles are distinguished from ordinary bubbles by their very small scale and their ability to remain dispersed in liquid for extended periods. That makes terminology especially important, because it links physical behavior with measurement practice and application design. TS ISO 20480-1 defines the language layer of that subject; it should not be read as claiming detailed performance limits or test procedures beyond the terminology scope stated for this part.
