Ultrasonics. Power measurement. Radiation force balances and performance requirements Ingestion-build-54371 BS EN 60238 applies to1 Scope This International Standard specifies a method of determining the total emitted acoustic power of ultrasonic transducers based on the use of a radiation force balance; establishes general principles for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; establishes limitations of the radiation force method related to cavitation and temperature rise; establishes quantitative limitations
