It is a good idea to ask your equipment repair providers or equipment suppliers to ensure that the vibration levels of the equipment they supply meet your standards. Once your facility takes ownership of the equipment from the supplier or repair provider,  the responsibility for any repairs usually becomes yours. This means any failure modes (bearing defects, misalignment, unbalance, resonance, etc.) are the responsibility of your facility to repair.

This creates additional costs and reduced reliability.

You can include vibration acceptance criteria and other standards in the purchase order that is issued. This way you can hold the repair provider or supplier accountable for any bad practice repairs or bad practice installation methods they may use on your equipment.
