1   Scope This European Standard relates to piezoelectric transducer ceramics for application both as transmitters and receivers in electroacoustics and ultrasonics over a wide frequency range. They are used for generation and transmission of acoustic signals, for achievement of ultrasonic effects, for transmission of signals in communication electronics, for sensors and actuators and for generation of high voltages in ignition devices. Piezoelectric ceramics can be manufactured in a wide variety of shapes and sizes. Commonly used shapes include discs, rectangular plates, bars, tubes, cylinders and hemispheres as well as bending elements (circular and rectangular), sandwiches and monolithic multilayers. Relevant sections of IEC 60302 “Standard definitions and methods of measurement for piezoelectric vibrators operating over the frequency range up to 30 MHz” and IEC 60642 “Piezoelectric ceramic resonators and resonator units for frequency control and selection” have been taken into consideration when drafting this standard.
