New Establishment and Revision of the Japanese Industrial Standards (JIS) (December 2021)

- Establishment and revision of the JIS, including for preformed flexible elastomeric foam thermal insulation materials -

December 20, 2021

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.

1. Outline of the new establishment and revision of the JIS

In December 2021, METI established 11 new standards and revised 23 existing ones (Appendix 1). In particular, METI believes that the following establishments of JIS are especially important.

1. Establishment of JIS for preformed flexible elastomeric foam thermal insulation materials

Insulation materials are used in plumbing, ducts, etc. in buildings and homes. They play an important role in conserving energy and creating comfortable interior environments in buildings, including preventing condensation and stopping hot and cold air from heating and cooling systems from escaping. In Japan, mineral fibre and cellular plastic insulation materials are becoming popular. In recent years, however, the focus has been on preformed flexible elastomeric foam with closed cell structure for reasons such as ease of installation and resistance to pipe corrosion.
While it is beneficial for both the user and the manufacturer to objectively evaluate the quality and performance of these new products, there has been no standard for preformed flexible elastomeric foam thermal insulation materials until now. This JIS was established using the Standardization System for the Creation of New Markets.* This is expected to increase reliability and awareness, cause usage to spread, and expand the market.

*This system supports standardizing technologies and services that are difficult to promote through the conventional standardization process, such as those that span multiple relevant organizations and advanced technologies owned by specific companies. For an overview of the system, see here.

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.
