New Establishment and Revision of the Japanese Industrial Standards (JIS) (August 2019)

Establishment and revision of the JIS, including those for automatic weighing instruments for filling and for assessing the reliability of optical fiber amplifiers

August 20, 2019

The Japanese Industrial Standards (JIS) is a collection of national standards stipulating the criteria for mineral or industrial products, data and services in Japan, including their quality, performance and test methods. The Ministry of Economy, Trade and Industry (METI) has been revising and newly establishing such standards in response to societal and technological changes. METI publicly introduces the newly established and revised standards which are especially important for the economy and for the public once a month in a press release.

1. Outline of the new establishment and revision of standards

In August 2019, METI newly established two and revised ten standards (see Appendix 1). In particular, METI believes that the following revisions of the existing standards are especially important.

(1) Revision of the JIS for automatic weighing instruments for filling or other purposes

The Measurement Act stipulates measuring instruments mainly used in transactions or certifications as “specified measuring instruments” and provides regulations targeting manufacturers, repair or sales business operators and users thereof so as to secure accurate measurement by such instruments.

The Act requires the government to stipulate the technical standards for specified measuring instruments under the JIS system. Accordingly, METI revised the JIS for three types of automatic weighing instruments,* including such instruments for filling, for which verification system under the Act will be commenced from April 1, 2020.

This revision is expected to help businesses to improve technical innovations for automatic weighing instruments and meet international trends in this field and it is also expected to contribute to improving the reliability of transactions or certification involving such instruments.

*Note: The term “automatic weighing instruments” refers to weighing instruments that work to gain measurement results in accordance with predetermined programs, unlike non-automatic weighing instruments generally found in stores and other businesses, in which no operator, as an intermediary, is needed in the process of measuring. Industries usually make use of automatic weighing instruments by incorporating them into production lines mainly in plants.

Note: The JIS for automatic catchweighing instruments (JIS B7607) were revised in August 2018 and have already been referred to in the related Ministerial Orders in March 2019.

(2) Revision of the JIS for methods for testing the reliability of optical fiber amplifiers

Societies’ increasing needs for high-speed networking systems and communication has led to an increase in the use of optical fibers.

Highly-reliable optical fiber amplifiers are indispensable for successfully transmitting optical signals over a long distance.

In line with the revision of the related international standards, METI revised the JIS for methods for testing the reliability of optical fiber amplifiers so that Japanese industries in the field of optical fiber amplifiers are able to introduce cutting-edge technologies in their products while reflecting market demands in their products.

This revision is expected to: help businesses procure products of stable quality worldwide at appropriate prices; and contribute to further expanding the range of application of optical communication systems.

2. Outline of the JIS

Stipulated under the Industrial Standardization Act, the JIS are a collection of national standards certified by the government of Japan, aiming at the quality improvement of mineral or industrial products, data (electromagnetic records) and services as well as at enhancing functions and safety thereof and streamlining of production and other operations thereof.

The JIS stipulate types and quality of products, data, services and other products, test or assessment methods for ascertaining such types and quality, and the values of standards that businesses are required to meet. Producers, service providers, product users and consumers and other stakeholders, for example, make use of these standards in their approaches to accessing quality products and enjoying provision of services in a secured manner.

METI has been establishing new standards or revising the existing ones for the JIS in response to technological advancements, changes in societal environments and other elements, if necessary.

4. Partial revision of the Industrial Standardization Act

The Bill for the Act of Partial Revision of the Unfair Competition Prevention Act, etc. (Act No. 33 of 2018) was approved at the 196th ordinary session of the Diet in 2018 and the Act was established. In line with this, the Industrial Standardization Act was partially revised to newly entitle data and services as targets of standardization under the Japanese Industrial Standards (JIS) and to change the title of the Industrial Standardization Act from “Kogyo Hyojyunka Ho” to “Sangyo Hyojyunka Ho” in Japanese as well as the title of the Japanese Industrial Standards (JIS) from “Nihon Kogyo Kikaku” to “Nihon Sangyo Kikaku” in Japanese. The revised Act came into force on July 1, 2019.
