Ultrasonics. Power measurement. High intensity therapeutic ultrasound (HITU) transducers and systems Ingestion-build-228203 For railway tracks1 Scope This International Standard establishes general principles relevant to HITU fields for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; specifies a calorimetric method of determining the total emitted acoustic power of ultrasonic transducers based on the measurement of thermal expansion of a fluid filled target; specifies requirements related to the statement of electrical power
