IEC 60068-2-65:2013 provides standard procedures 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. This second edition cancels and replaces the second edition, published in 1993, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - minor technical and editorial changes were made throughout the document as originally requested by the DE National Committee; - following comments at the CD stage, particularly from the UK National Committee, significant technical and editorial additions were made to the standard for acoustic testing employing the progressive wave tube technique.
