International standardization of Ultrafine Bubbles


The ultrafine bubble technology has been utilized in various applications such as no-detergent cleaning water and separating silicon wafers, however, its terminology, measurement method, performance evaluation, have not been defined clearly. Certification system is also not established, which hinders the growth of ultrafine bubble technology and products on a global scale.

Importance of Fine Bubble Technology Standardization by ISO Three-layer International Standards and Certification

Under the current situation in which neither fine bubble nor the technology are defined clearly, each manufacturer might claim the performance of their ultrafine bubble products based on their own understanding and definition. Since this may cause confusion and disadvantages to consumers, standardizing the fine bubble technology is vital to the healthy growth for both the customers and the industry.

In this standardization activity, Japan has proposed a three-layer standard structure modeled after the A-B-C three-layer standard system, i.e. ISO 12100 for the safety of machinery and risk assessment. In "Basic Standards," the basic common elements related to fine bubble technologies are defined. In Group Standards, measurement methods are specified.
In Individual Application Standards, specific technical requirements for industrial applications are defined.

Fine bubbles are an innovative technology that was born in Japan, but without the creation of proper standards with as a premise to industrial development, there may be obstacles and concerns regarding the development of related industries and the progress of related technological developments. As a basis for promoting international standardization, certification, development of application technology, and collecting and sharing information, FBIA will strive to create the healthy market of fine bubble technology in cooperation with industry, academic conference, and government.

Business of the FBIA
Three key focuses as industrial joint projects are as explained below.

1. International Standardization / Certification

[1] International standardization of measurement methods for fine bubbles

(1) Joint standardization with the Standardization Investigative Commission of AIST

(2) Implementation of international standards through the Ministry of Economy Trade and Industry's "International Standardization Joint Development Project" (Adopted on August 29th, 2012)

(3) Implementation of various joint research and development projects that are necessary for the abovementioned international standardization

[2] Implementation of certification technology development and product certification for Fine Bubbles Generators, measurement devices, application devices and product materials

2. Common Fundamental Technology Development Project

FBIA plans to conduct a joint research and development (measurement methods, operation tests, etc.) with the Terasaka Laboratory at Keio University and member companies. Additionally, joint development with AIST and other universities is under consideration.

3. Projects for the Collection and Providing of Fundamental Information

FBIA plans to conduct a joint information gathering project with a large think-tank regarding the market size and related companies of the fine bubble industry, and provide the results to members. FBIA also plans to implement fundamental data services, and have a website and up-to-date information on information sites such as Wikipedia for global recognition.
