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

Establishment and revision of JIS, including JIS for measurement methods for performance of solar radiation retro-reflectivity on adhesive films for building glazing, methods for measuring energy consumption of machine tools, and flow battery energy systems for stationary applications

February 22, 2021

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 JIS

In February 2021, METI newly established 8 standards and revised 57 standards (see Appendix 1). In particular, METI believes that the following establishment of new standards is especially important.

(1) Establishment of JIS for measurement methods for performance of solar radiation retro-reflectivity on adhesive films for building glazing

Application of solar radiation retro-reflective films (*1) to building grazing brings about not only enhanced heat insulation performance that contributes to summertime air conditioner-based electricity consumption efficiency, but also mitigates outdoor heat environments, such as paved streets. Despite these advantages, there were no standards that objectively assess the performance of this type of products. To address this, METI established a new JIS to help users and purchasers choose desirable products by referring to their solar radiation retro-reflectivity (*2) performance and other characteristics.

This establishment will permit users and purchasers to objectively assess solar radiation retro-reflective films. Moreover, it is expected to contribute to creating new markets not only in Japan but also in Southeast Asia and other regions through dissemination of this JIS in such regions where urbanization is recently advancing, thereby further contributing to reduction of greenhouse gas emissions.


1. The term “solar radiation retro-reflectivity” refers to a reflective property in which incident light is reflected at specific angles in the direction from which the light has entered.
2. The JIS was established by taking advantage of the Standardization Program for New Market Creation.*
*Note: The Standardization System for Cultivating New Markets aims to encourage smooth standardization of cross-sectoral fusion technologies between multiple related associations or for cutting-edge technologies owned by specific companies, in which the existing industrial and other associations cannot advance standardization activities. Under the system, if predetermined requirements are met and a target technology is adopted as an appropriate one for the system, METI is permitted to undertake standardization of the technology even without receiving active cooperation of related industrial and other associations.

(2) Establishment of JIS for methods for measuring energy consumption of machine tools

Introduction of environmental rules industrial machinery to reduce environmental burdens within industries has been advancing mainly in Europe. To address this trend, it is an urgent matter for Japan to also establish domestic standards for methods for designing machine tools in which environmental performance is taken into consideration.

Against this backdrop, METI established JIS for methods for measuring energy consumption for machine tools. The establishment of this JIS is based on the international standard which was established by Japan’s proposal.

This establishment is expected to contribute to disseminating methods of designing machine tools with enhanced energy-saving performance, reducing the energy consumption of such tools.

(3) Establishment of JIS for flow battery energy systems for stationary applications

As electricity outputs generated by photovoltaic and wind power generators are disadvantaged by climate condition dependency, storage battery technology is indispensable for dissemination of these generators to balance human-centric energy demand with nature-centric energy supply patterns. One such potential batteries known as flow battery energy systems for stationary applications (hereinafter referred to as “FBES”) are appropriate for enlarging the capacity and output of storage batteries and characterized by longer life and low risk of overheating or fire. Despite this promising advantage, there were no methods for appropriately assessing the performance and safety of FBES.

To address this situation, under the leadership of Japan, an international standard for assessing the performance and safety of FBES was established in February 2020. In line with this, METI established a JIS for FBES based on the international standard. This establishment is expected to help objective assessment of the performance and safety of FBES and to contribute to enhancing the stability of power grids and disseminating renewable energy.

As seen in the figures above, FBES, which are electrolyte tanks filled with metallic ions (e.g. vanadium) are capable of large-scale output and storage.

2. Outline of the JIS

The JISs 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 secured 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.
