Description / Abstract:

This American National Standard provides specific guidance for assessing the severity of vibrations measured on bearing housings of shipboard machinery so as to ensure reliable mechanical operation.

The criteria provided in this Standard apply to the vibration of all non-reciprocating machinery on board surface ships, except for main propulsion machinery. They apply to broadband vibration measurements taken on the bearing housings, or as close as possible to the bearing supports, of machines under steady-state operating conditions with normal operating conditions of speed and load. For further evaluation of gears and rolling element bearings, measurements of frequency components may be needed.

This Standard applies to acceptance tests on new machinery (shop tests or on-board tests) and to in-situ tests on existing machinery on board ship. The criteria are applicable only for the vibration produced by the machine itself and not for vibrations which are transmitted to the machine from the outside environment.
