New Establishment and Revision of the Japanese Industrial Standards (JIS) (October 2020)

- Establishment and revision of JIS, including JIS for coal-gasification slag-aggregate for concrete -

October 20, 2020

The Japanese Industrial Standards (JIS) is 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 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 October 2020, METI newly established 4 standards and revised 14 standards (see Appendix 1). In particular, METI believes that the following establishment of the JIS is especially important.

Establishment of the JIS for coal-gasification slag-aggregate for concrete

Integrated coal gasification combined cycle (IGCC) is a technology that dramatically improves power generation efficiency compared with the conventional coal-fired power generation and achieves substantial reduction of carbon dioxide emissions, and this advantage is expected to facilitate commercialization of the technology. In the process of IGCC-based power generation, coal-gasification slag is generated as a by-product. This material is expected to partially replace sand and gravel which are generally used as aggregate for making concrete. However, no standard for quality, e.g., performance and safety, or test methods of coal-gasification slag had been stipulated. To address this situation, METI established JIS A 5011-5 for this material.

This establishment is expected to contribute not only to improving trust in the quality of coal-gasification slag-aggregate for concrete and disseminating the material but also to reducing the amount of natural aggregate used for concrete, whose production amount has tended to decrease recently.

2. Outline of the JIS

The JIS stipulate types and quality of products, data, services, etc., test or assessment methods for ascertaining such types and quality, and the values of standards that businesses are required to meet. Producers, service providers, product users and consumers and other stakeholders, for example, make use of these standards in their approaches to accessing quality products and enjoying provision of services in a secure manner.

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