Abstract
Results of works on improvement of the state primary special measurement standard of ultrasound power unit in water GET 169-2005 are given. As a result of the inclusion of two new reference ultrasound power meters in the standard, the frequency and dynamic ranges of reproduction and transmission of the power unit to lower-level measuring instruments were expanded using absorbing targets for measuring the radiation effect of the ultrasonic wave and the absorbed ultrasonic energy. That is very important for metrological support of modern high-tech medical ultrasound equipment, including focused high-intensity ultrasound beams for the treatment of cancer. The automation of the measurement process used in the updated standard has reduced significantly the complexity of verification procedures increasing the accuracy of measurements.
