New Establishment and Revision of the Japanese Industrial Standards (JIS) (April 2022)

- JIS established and revised for matters including methods for measuring the magnetic properties of permanent magnets and validation/verification -

April 20, 2022

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 April 2022, METI established 2 new standards and revised 7 existing ones. Of these, METI believes that the following establishments are especially important.
Among these standards, 1 established standard and 1 revised standard were submitted by the Japanese Standards Association (JSA), an Accredited Standards Developing Organization (see Appendix 1).

(1) Establishment of a JIS regarding methods for measuring the magnetic properties of high-performance permanent magnets

A Japanese Industrial Standard (JIS) has been established regarding the methods for measuring the magnetic properties of high-coercivity permanent magnets. Magnets like these are used in generators and in the motors in, for example, electric vehicles, wind power generators, industrial robots, and household appliances. The newly established JIS is the world's first standard on using a superconducting magnet to accurately measure the magnetic properties of high-performance permanent magnets. Consequently, it is expected to promote further improvement of their performance, and thereby contribute to the development of environmentally friendly equipment, for example. (See Appendix 2.)

(2) Establishment of a JIS regarding validation and verification

A key step toward achieving carbon neutrality is to establish a framework whereby companies will calculate their own greenhouse gas (GHG) emissions and publish the relevant information thus obtained. If this framework is to function correctly, the information concerned will need to be reliable. However, it is not easy to determine whether the information companies publish on their emissions is reliable.

Two processes are required to do this: one confirming that the investigations and other approaches they are going to adopt will be valid (validation), the other confirming that those they have adopted thus far are correct (verification).

To address this, METI has established JIS Q 17029, a standard that stipulates conditions that must be met by bodies that conduct this kind of validation and verification, with information pertaining to carbon neutrality being one example. Adhering to this standard is expected to ensure consistency regarding validation and verification, and consequently improve reliability. (See Appendix 3.)

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 these standards for purposes such as 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, doing so as necessary.
