MIL-STD-167-2A outlines the requirements for mechanical vibrations in shipboard equipment, specifically focusing on type II-environmental vibration, to ensure durability under operational conditions. The standard details testing procedures for detecting, designing, and validating equipment against structural failure caused by vibrations during service [1,2].
