A working group has prepared a draft.

Abstract

This document specifies a test method to evaluate filters for use in controlling the characteristic of ultrafine bubble diluent for industrial process and measurement. Application of single filtering mode, series application mode of multiple filter and application mode of washing after a single filtering are described as typical case. Ultra-fine bubbles, unlike solid particles, are easily compressed and expanded, split, dissolved. When the water passage through micropores, it is investigated whether UFBs behave similarly to solid particles or not.
