Scope

This standard specifies the measurement conditions and methods, for sound power and
sound field characteristic parameters of high-intensity focused ultrasound (HIFU) in
water, within the frequency range of 0.5 MHz ~ 5 MHz.
This standard applies to high-intensity focused ultrasound systems.
Note 1: This standard uses SI units. In some parameter descriptions, such as the beam area
parameter and the sound intensity parameter, it may be more convenient to use other units. For
example: The unit of sound beam area can be cm2; the unit of sound intensity can be W/cm2 or
kW/cm2.
Note 2: The measurement range specified in this standard: the power is not more than 500 W;
the sound intensity is not more than 5000 W/cm2.
