Overview
Part 2-65 of DIN EN 60068 specifies test methods and guidance for conducting acoustic tests in order to determine the ability of a specimen to withstand vibration caused by a specified sound- pressure level environment to which it is, or is liable to be, subjected. For sound pressure level environments of less than 120 dB acoustic tests are not normally required. The standard determines the mechanical weakness and/or degradation in the performance of specimens and to use this information, in conjunction with the relevant specification, to decide on their acceptability for use. The methods of test may also be used as a means of establishing the mechanical robustness or fatigue resistance of specimens. DIN EN 60068-2-65 describes two procedures for conducting tests and for measurement of the sound pressure levels within the acoustic noise field and considers the need for measurement of the vibration responses at specified points on the specimen. It also gives information for the selection of the acoustic noise environment, spectrum, sound pressure level and duration of exposure. Compared to the previous edition, minor technical and editorial changes were consistently introduced in the document and, on the other hand, the test methods were revised by acoustically induced vibration using a progressive wave channel. Compared to the previous edition, minor technical and editorial were made throughout the document and acoustic testing employing the progressive wave tube technique.
