ISO 13355:2016 specifies a method to carry out a vertical random vibration test on a complete, filled transport package(s) and unit loads using random excitation[1]. This document also provides methods for assessing the performance of a package in terms of its strength or the protection that it offers to its contents when it is subjected to vertical vibration. The test discussed in this document can be performed either as a single test to investigate the effects of vertical vibration, or as a part of a sequence of tests designed to measure the ability of a test specimen to withstand a distribution system that includes a vibration hazard.

NOTE In this International Standard, a package or unit load is referred to as test specimen.

[1] Random vibration theory is discussed in IEC 60068-2-64.
