IEC 60068-2-55:2013 provides a standard procedure for determining the ability of a specimen to withstand specified severities of bounce, e. g. when transported as loose cargo on wheeled vehicles. This second edition cancels and replaces the first edition, published in 1987, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: This new edition allows for loose cargo testing in a more general sense. The test is no longer aligned with a special testing machine but allows for use of any suitable equipment such as electrodynamic or servo-hydraulic shaker tables. Moreover, sinusoidal and random vibration can be used. The previous rotation table motions are included in Annex A as historical methods. This publication is to be read in conjunction with /2.
