The aim of this project was to devise realistic tests of electronic equipment. In order to determine the range of vibration stresses actually occurring both above and below ground, 699 acceleration tests were conducted on 168 pieces of equipment at different locations. The measurements obtained were converted by Fourier transform into frequency-acceleration value-pairs, which were then used to establish a load spectrum for tests. The data constitute a solid foundation on which to establish a test procedure. Recommendations based on existing standards are made with respect to sweep speed and test duration. Individual electronic equipment components were tested using a vibration generator, and it was possible to demonstrate and eliminate the effect of low frequency vibration on the operation of equipment in which static forces arise. The effect of vibration on mechanical stability and on the behaviour of switching devices was observed.
