AIST Stories No1

From AIST to the Innovative World26Our daily lives and economic activity are inseparably bonded with measurement. Daily life would more than likely be thrown into utter confusion if measuring apparatus delivered mistaken results. The National Metrology Institute of Japan (NMIJ), part of AIST, plays an important role in maintaining the accuracy of measurement, which is a foundation of safe and secure life. Advances in metrological technology are called for accompanying changes in society and technology. Technology research and development is underway targeting more accurate metrology.The leading organization in Japan for metrological technologyThe people and technology behind correct measurement, which is quite common nowadaysThe role of AIST supporting accurate measurement and the future of measurementNational Metrology Institute of Japan (NMIJ)Laws for correct measurement The Measurement ActIn our day-to-day lives we are constantly measuring. We shop for things and concern ourselves with how much two-hundred grams of beef will cost, or how much a half liter bottle of milk will cost; when we cook, we measure ingredients with a measuring cup or spoon. When it comes to our health, we measure our blood pressure and we pay our public utility charges for electricity, gas, and water based on usage measured by meters.We generally have very few complaints regarding the actual amounts that are measured. We use scales* and rulers, and pay for products based on measurements made by other people. Accurate measurement has become a given for us in today’s world. And why is this the case? Because measurement standards are prescribed in Japan by a law known as the Measurement Act, and people involved with measuring strive to abide by this act.There are two primary objectives of the Measurement Act. The first is to establish measurement standards (establish measurement units, etc.). The second is to ensure accurate execution of measurement (mandating of accurate measurement, etc.). Based on this act, measuring apparatus for measurement of weight (kg) and volume (l) are called “specified measuring instruments” and they must be inspected and certified when shipped or prior to use as being able to measure correctly, as well as periodically inspected and certified forthwith. In fact, the scales used by your local butcher must be regularly inspected.Ensuring traceability through national standardsAIST’s National Metrology Institute of Japan (NMIJ) is Japan’s leading organization when it comes to the field of metrology.
