DANSK DSF/ISO/FDIS 20283-5 PDF

This part of ISO 20283 gives guidelines for the measurement, evaluation and reporting of vibration with regard to habitability for all persons on board of passenger and merchant ships, especially for crew. Overall frequency-weighted r.m.s. vibration values in the frequency range 1 Hz to 80 Hz are given as guideline values for different areas on ships. This part of ISO 20283-5 is applicable to passenger and merchant ships with intended voyages of 24 h or more. This part of ISO 20283 specifies requirements for the instrumentation and the procedure of measurement in normally occupied spaces. It also contains analysis specifications and guidelines for the evaluation of ship vibration with respect to habitability. The evaluation of low-frequency ship motion which can result in motion sickness is covered by ISO 2631-1. For the evaluation of the global structural vibration of a ship, however, see ISO 20283-2.
