This international standard specifies a method to carry out a vertical random vibration test on a complete, filled transport package(s) and unit loads using a random excitation . This test may be used to assess 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. It may 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 the following text a package or unit load is called a test specimen.
