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

Establishment and revision of the JIS, including kira-contained ceramic blocks for paving, commercial gas stoves and appropriate use of reference materials

April 20, 2019

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 2019, METI newly established 5 standards and revised 12 standards (see Appendix 1). In particular, METI believes that the following establishment and revision of standards is especially important.

(1) Establishment of the JIS for kira-contained ceramic blocks for paving

Kira,* fine sand containing clay which is a residue generated in selecting silica sand, has been considered as waste material mainly discarded due to little use for it in any products. However, as it was found that kira exhibits good performance in water absorption and retention if it is used as a raw material in ceramics blocks for paving, kira is expected to be utilized for countermeasures against heat in cities, such as the heat-island phenomenon.

Meanwhile, no industries have ever determined definitions of kira’s performance in water absorption and retention or methods of testing such performance, and this situation has raised concerns over distribution of inferior-quality products. To address this situation, METI established new standards for such blocks, i.e., JIS A5216, taking advantage of Standard Development Program for the Creation of New Markets.

Dissemination of the standards is expected to further popularize kira-contained ceramic blocks for paving and to encourage related industries to effectively make use of such blocks.

*Note: The term “kira” is a generic name for fine particles containing a small amount of clay, e.g., silica sand and feldspar. Kira is generated in refining raw materials for pottery, e.g., cement and bricks, and its median diameter (as a mean value of the grain size distribution) is between 10 μm and 40 μm, while its grain diameter is between 1 μm and 200 μm, which is inappropriate for use as raw materials for pottery.

(2) Establishment and revision of eight JIS, including those for commercial gas stoves

Aiming to swiftly address the introduction of new technologies into gas equipment and development of new products involving gas equipment, Japan has revised the Ministerial Order for Technologies Standards and Other Rules for Liquefied Petroleum Gas Equipment, etc. and other laws and regulation and shifted from “specification-based regulations” that stipulate detailed standards for structures, quality of materials and other element of gas equipment under ministerial orders to “performance-based regulations” that stipulate safety performance of products that related businesses should achieve.

To appropriately operate the performance-based regulations, it is important for Japan to establish new JIS and revise the existing JIS as standards for technologies exemplified in approaches to operation and interpretation of these laws and regulations. To this end, METI established and revised eight JIS, including those for commercial gas stoves.

(3) Revision of the JIS for appropriate use of reference materials

Reference materials are indispensable for improving the accuracy and reliability of measurement and analysis. JIS Q0033 stipulates standards for guidelines according to which personnel that intend to measure and analyze target products are able to appropriately utilize all reference materials used in markets and assess the results derived from the measurement and analysis. Recently, industries are facing ever-more types of reference materials and expanded utilization thereof. In response, to provide standards for guidelines for use of all reference materials, METI revised JIS Q0032 (calibration in analytical chemistry and use of certified reference materials) and JIS Q0033 (uses of certified reference materials) and integrated them into one JIS: JIS Q0033.

This integration is expected to raise the level of common understanding of appropriate use of reference materials in general and to further enhance the accuracy and reliability of measurement and analysis.

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 JIS or revising the existing ones in response to technological advancements, safety requirements and other societal changes as 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 the “Kogyo Hyojyunka Ho” to the “Sangyo Hyojyunka Ho” in Japanese as well as the title of The Japanese Industrial Standards (JIS) from the “Nihon Kogyo Kikaku” to the “Nihon Sangyo Kikaku” in Japanese.
