New Establishment and Revision of the Japanese Industrial Standards (JIS) (May 2021)

- Establishment and revision of the JIS, including the design management requirements for USB and other universal communication ports -

May 20, 2021

The Japanese Industrial Standards (JIS) are 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 these standards in response to societal and technological changes. METI publicly introduces the newly established and revised standards that are especially important for the economy and the public once a month in a press release.

1. Outline of the new establishment and revision of the JIS

In May 2021, METI established 12 new standards and revised 12 existing ones. Among these standards, it established 5 standards and revised 3 standards based on proposals prepared by the Japanese Standards Association (JSA). This is an Accredited Standards Developing Organization that can propose the establishment, revision, etc. of JIS without the need for discussion by the Japanese Industrial Standards Committee (JISC), pursuant to the revision of the related law in July 2019 (see Appendix 1). In particular, METI believes that the following establishments of JIS are especially important.

Newly established JIS for Safety requirements for USB and other universal communication ports

Communication cables and ports are becoming more standardized and devices equipped with universal ports such as USBs are spreading rapidly. As power transmission using these cables and ports becomes more common, the risks of electric shock and fire will increase. The existing JIS did not provide sufficient safety requirements regarding this power transmission.
In order to avoid such risks, METI has established JIS C 62368-3, " Audio/video, information and communication technology equipment-Part 1: Safety requirements" The widespread use of this JIS is expected to improve safety during power transmission for devices that are supplying or receiving power from USB ports, etc.

2. Outline of the JIS

The JIS stipulate the types and quality of products, data, services, etc., test or assessment methods for ascertaining these types and quality, and standard values that businesses are required to meet. Producers, service providers, product users and consumers and other stakeholders make use of and/or benefit from these standards in order to produce and/or by being able to access quality products and services with peace of mind.
METI has been establishing new standards or revising existing ones for the JIS in response to technological advancements, changes in the social environment and other factors.
