  1. Vibration Limits: The standard sets limits for vibration levels on shipboard machinery, including maximum allowable amplitudes, velocities, and accelerations.
  2. Noise Limits: MIL-STD-167-2A establishes noise level limits for various shipboard spaces, including machinery rooms, mess halls, and berthing areas.
  3. Design and Testing: The standard requires that shipboard machinery be designed and tested to minimize vibration and noise. This includes consideration of factors such as balancing, alignment, and foundation design.
  4. Instrumentation and Measurement: The standard specifies the instrumentation and measurement techniques to be used for vibration and noise testing.
