Setting measurement standards and developing intellectual techno-infrastructures for measurement, testing, and certification to support technological innovation and a fair and secure society
　Measurement is necessary for designing and developing products as well as for testing and certifying their qualities. It serves as a driving force to maintain Japan’s industrial competitiveness, and as an intellectual technoinfrastructure for sharing technical policies to maintain the security of society and the lives of individuals, preserve the environment, and maintain energy and resources. AIST develops and maintains national measurement standards in order to ensure global acceptability of consistency, of relevant technologies, and is systematically developing measurement technologies from the standpoint of intellectual infrastructure.

Development of new national measurement standards and dissemination of measurement standards to industrial and social users

AIST develops new national measurement standards required to specifically support “green innovation” that promotes energyefficient technologies, also “life innovation” to ensure food safety, and industrial competitiveness such as facilitating the application of advanced industrial technologies to Japanese industry, in response to the rapidly growing global market, and keeps providing national calibration services to users.

Development and standardization of advanced measurement technologies

In order to improve the development and design of new products and support a fair and secure society, AIST develops advanced measurement techniques as well as basic evaluation techniques and measuring instruments, develops industrial standards and conformity assessment techniques, and provides solutions to measurement problems arising at production lines of industrial sectors, as well as trains measurement experts.

Improvement on basic national easurement standards

The improvement on basic national measurement standards required to ensure the reliability of industrial measuring instruments is intended to respond to new measurement needs for high-performance metrology at production sites, refinement on national traceability hierarchy, direct application of national metrology standards to certification at production sites, and application of on-demand calibration service for small and medium size enterprises to strengthen their R&Ds.

Contribution to and leadership in the global metrology system

Our international activities lead the global metrological system for international mutual acceptance of measurement standards and measuring instruments and global standardization on measurement technologies. Included is the cooperation for the redfinition of basic units such as the kilogram and second. Our dissemination activities also cover the training of metrological experts and verification experts for domestic industrial and regulatory activities, and the metrological administration officers based on the measurement law of Japan.

Development and administration of database as intellectual infrastructure for innovation

In order to support domestic industrial activities for innovations, we update a reliable and sustainable database and maintains and disseminates it through our website over the world. It includes spectral database for organic materials and thermal properties for industrially important materials, and it has served more than 50 million visitors a year from the world.
