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 Electrotechnical Commission (IEC) on all matters of

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

The recent progress in the application of fine bubble technology exhibits successes in the various

technical fields such as environmental technology in water and washing and cleaning technology for

mechanical engineering. The applications for agro- and aqua- farming and food industrial field also

draw high interests of markets in view of fine bubble enabled performance in enhancing growth of

agro- and aqua- products, improving their quality, saving resources for farming and ensuring safety

of the food products. Various industries engaged in such products are introducing the fine bubbles to

their farming field by applying fine bubble generating systems, eventually creating new market for the

generating systems.

However, since technology transfer from fine bubble technology to technology fields of agro- and aqua-

farming and food industries is not well supported by common understanding of the fine bubbles or their

generating technology, results of evaluation on fine bubble enhanced performance cannot be accepted

commonly by both generating system suppliers and its users at the transaction scene. Furthermore,

a variety of agro- and aqua- farming products makes it difficult to adopt a systematic approach for

selection and application of generating systems.

The performance evaluation based on objective evidence resulting from standardized procedures

is intended to bridge the two technologies and facilitate diverse fields of applications for fine bubble

technology in the global market. In order to accelerate sound global market formation, development of

test procedures is urgently demanded by both technology stakeholders.

This document is intended to meet these needs by specifying the test procedure to be applied to the

generating system for agro- and aqua- farming and food industries uses. The evaluation is made by

applying fine bubble water generated by the object system to lettuce and by measuring its growth. The

product, lettuce, is globally accepted and the yielded test data represents the performance of the tested

system over other products in such major product family as, for example, leaf vegetable. The growth

process of lettuce is much simpler than other vegetables making the measuring process much easier in

the test procedure. The specified test conditions, namely the environment for growth, are also easy to

be controlled allowing many testing plants globally available. The parameter measured is the change in

the harvested mass of lettuces with application of fine bubbles compared to that without application in

a specified period of growth.

Since the performance in terms of parameters is improving rapidly as the technology evolves, the

quantitative criteria for the testing are not specified in this document.
