New Establishment and Revision of the Japanese Industrial Standards (JIS) (April 2018) Revision of the JIS, including standards for safety colors and safety signs.

The Japanese Industrial Standards (JIS) is a collection of national standards stipulating the criteria for products to be sold in Japan, including their types/scales, quality/performance and safety. 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 April 2018, METI revised 4 standards (see Appendix 1). In particular, METI believes that the following revision is especially important.

Revision of the JIS for safety colors and safety signs

Meanings of safety signs, such as those relating to prohibited matters and safeness measures, should be clearly understandable when people see them even from a distance. The designs and color tones of those signs determine the degree of which people can recognize meanings of those signs.

METI considers it is necessary to enhance recognition of safety signs among people whose color visions vary, while harmonizing related domestic standards to corresponding international standards. In light of this, METI revised JIS Z 9103 (Graphical symbols-Safety colours and safety signs- Part 4: Colorimetric and photometric properties of safety sign materials) to adopt the color schemes under the Universal Design system in which colors of signs are selected by research on people’s recognition of color combinations. These revisions are expected to support people whose color visions vary, as well as overseas visitors in Japan, to secure safety and to improve the user friendliness of signs.

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 improvement of mineral or industrial products in terms of quality, performance and safety, as well as at increasing and enhancing production efficiency and other areas.

The JIS stipulate a variety of product criteria, including types/scales, quality/performance, safety, testing methods for assessing these criteria, and other standard criteria that products should meet. These standards are utilized to ensure product reliability in quality for manufacturers, users and consumers.

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