Material Strength Standards Group
- The Material Strength Standard Research Group provides measurement standards related to material strength and underwater ultrasonics. In the field of material strength, the group researches calibration and uncertainty evaluation methods for hardness standards and evaluation methods for mechanical properties related to material hardness, and maintains and provides measurement standards mainly for Rockwell and Vickers hardness. In the ultrasonic field, we research ultrasonic sound field measurement techniques useful for evaluating ultrasonic equipment, and maintain and supply measurement standards for free-field sensitivity calibration of hydrophones used to measure ultrasonic power and sound pressure emitted from sound sources.
