GB/T 28784.5-2022 is the Chinese standard "Mechanical vibration - Measurement of vibration on ships - Part 5: Guidelines for measurement, evaluation and reporting of vibration with regard to habitability on passenger and merchant ships".

Its scope clause reads: This document gives guidelines for the measurement, evaluation and reporting of habitability vibrations for all persons on board passenger and merchant ships, especially the crew.

The root mean square value of frequency-weighted vibration within the frequency range of 1Hz~80Hz is used as the evaluation value of different areas of the ship.

This document applies to passenger ships and merchant ships with an estimated voyage time of 24 hours or more. This document specifies the requirements for measuring instruments and measuring procedures in common functional areas, and also includes vibration evaluation for ship habitability. analysis specifications and guidelines.

The evaluation of low frequency motions of ships that may cause seasickness is specified in ISO 2631-1.For the content related to the vibration of the overall structure of the ship, see ISO 20283-2. Its clauses include terms and definitions.
