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.
