Proposals are presented for determining retentivity of polarization in ferroelectric ceramic elements for different applications. A test procedure is described for elements to be driven at high frequencies and intensities under steady state or pulse conditions, such as those used for delay line application. Test procedures are also presented for elements to be mechani-cally stressed and for elements working into both high and low impedance loads and subjected to nondestructive high impact and quasi-static- stresses.
