Paper Abstract

This paper outlines the current status of measurement standards for vibration and shock at the National Research Laboratory of Metrology of Japan. As for the vibration acceleration standards, two systems have been established. One system is for the middle and high frequency range (20 Hz to 5 kHz) and its acceleration range lies within 1 m/s2 to 100 m/s2. The other system is for the low frequency range (1 Hz to 200 Hz) and its acceleration range lies between 0.1 m/s2 and 100 m/s2. A test facility is under development to evaluate the accelerometers' performance in different temperature and humidity. With this facility, temperature of the test chamber can be varied from -40 degree(s)C to +100 degree(s)C and humidity from 20% to 90%. A calibration apparatus is also under construction to establish the national standard of shock acceleration in the high acceleration range from 102 m/s2 to 105 m/s2.
