Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The preparation work for International Standards is typically carried out through ISO technical committees. Each member body interested in the subject which involves a technical committee established has the right to be represented in that committee. International organizations, the governmental and the non-governmental, in liaison with ISO, also take part in the work. ISO closely collaborates with the International Electrotechnical Commission (IEC) on all the matters related to electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Introduction

Until now the terminology, method and corresponding technology for the generation of fine bubbles have not been standardized. The new project to standardize the terminology of fine bubble generating systems and the corresponding technology is thought to have significant influences on the market as follows:

• convenience of customers when purchasing or using fine bubble generating system and its techniques will be improved, and owing to the improvement of their convenience, it can be expected to boost fine bubble industries;
• standardization of terminology will enhance commonality in the field of generating system performance. Improvement in performances in hardware and software will also prospectively lead to market growth of the manufacturing industries of fine bubble generating system;
• standardization of terminology will enable the application markets to be boosted in creating new markets, as well as unifying existing markets.

In addition to existing fine bubble technology standards, by specifying"common terms" of generation principles, it will allow best practices to use common terms for fine bubble generating systems as well as the market expansion is expected.
