New Establishment and Revision of the Japanese Industrial Standards (JIS) (May 2018) New establishment and revision of the JIS, including standards for evaluation methods of green building materials and impact reducing Tatamidoko

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 May 2018, METI newly established 5 standards and revised 4 standards (see Appendix 1). In particular, METI believes that the following establishment of new standards is especially important.

1. Establishment of the JIS for evaluation methods of green building materials

As efforts for enhancing the energy conservation performance of building materials contribute to the realization of a low-carbon society, it is important to develop and popularize green building materials, or construction materials with enhanced energy conservation features and performance. To broadly popularize these materials, establishment of test methods by which markets can appropriately evaluate such materials are necessary. To this end, METI established JIS A1487 (Test method of thermal transmission properties for vacuum insulated building components) and JIS A2104 (Energy performance of windows for residential buildings-Calculation procedure) in the field of green building materials.

2. Establishment of the JIS for impact reducing Tatamidoko (bases for tatami mats)

Example of cross-sectional view of a typical impact-reducing Tatamidoko
Due to the fact that Japan is faced with an aging society, public demand for new types of floor materials that contribute to alleviating the risks associated with elderly people falling at home or at facilities is increasing. As one type of floor materials, there is a growing need for high-performance Tatamidoko that help the elderly walk safely on tatami mats and absorb shock to reduce the change of bodily injury from impact in the case of a fall.
To meet this new demand, METI established JIS A5917 (Impact reducing Tatamidoko) as standards for high-performance-shock-absorbing Tatamidoko, taking advantage of the Standards Development Program for the Creation of New Markets. The establishment of this new JIS is expected to enhance safety for the elderly and other people and to create new markets for housing and facilities.

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 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.
