The Draft International Standard ISO/DIS 2631 "Guide for the Evaluation of Human Exposure to Whole-Body Vibration" provides an excellent base for setting acceptable levels of vibration on ships.2 A standard for evaluating vibration levels has been needed for some time and the new standard not only provides a sound foundation for evaluating vibration, but also permits the vibration levels to be rated numerically as percentages of the established standard of fatigue-decreased proficiency. The standard is related to frequency, direction of motion, and the time exposure at the different locations in the ship. "Safe exposure limits" and "reduced comfort limits" are defined in terms of percentages of this same fatigue-decreased proficiency level.
