Fine bubble technology — Sampling and sample preparation for measurement — Part 1: Ultrafine bubble dispersion in water

This document specifies procedures and requirements for sampling and sample preparation of ultrafine bubble dispersions in water. This document is applicable to relatively stable dispersions where the size and number of bubbles are relatively constant for the duration of the sampling, sample preparation and measurement. This document is not applicable to less stable fine bubble dispersions or microbubble dispersions.
