**IN-SERVICE AND ACCEPTANCE CRITERIA**

A. [Procurement Clauses]{.underline}. During equipment procurement,
Table J-C3.1 should be used to identify the technology being used to
assess equipment condition for the type of equipment being procured. The
applicable sections as shown in Table J-C3.1 below shall be used in
Requests for Proposals (RFPs), and Requests for Quotations (RFQs); in
procuring new, or replacement of equipment; and in obtaining re-work of
existing equipment in this contract. The number of the clause containing
the applicable clause is located under the column heading \"Contract
Clause.\" The clauses may be used without modification, however, they
will have to be renumbered to fit the organization of the specification
in which they are used.

B. [In-Service And Acceptance Criteria]{.underline}. In-service and
acceptance criteria for vibration, thermography, electrical testing,
bearing selection, and oil analysis (hydraulic fluids, transformer oil,
and lubricating oils) are provided. Proactive techniques such as
alignment and balance criteria, age exploration (AE), and Facilities
Condition Assessment (FCA) are addressed.

C. [Leveling Installed Rotation Machinery]{.underline}. The Contractor
shall level all installed rotating electrical and mechanical machinery.
After installation, the equipment shall not exceed a maximum slope of
the base and the frame of 0.001 inch per foot. The Contractor shall
document the type and accuracy of the instrument used for measuring the
level; e.g., a 12-inch machinist's level graduated to 0.0002 inch per
foot.

> used in developing vibration criteria:
>
> [a.]{.underline} Obtain nameplate data.
>
> [b.]{.underline} Obtain vibration spectra on similar machines.
> Differences in baseplate stiffness and mass will affect the vibration
> signature.
>

> misalignment, bearing defect, impeller and/or vane, electrical, gear,
> belt, etc.
>
> [d.]{.underline} Construct a mean vibration signature for the similar

>
> [g.]{.underline} Collect vibration data on the new component at the
> recommended positions.
>
> [h.]{.underline} Compare the vibration spectrum with the mean spectrum
> determined in step (5) above as well as with the criteria and
> guidelines provided in this guide.
>
> [i.]{.underline} Any new piece of equipment should have a vibration
> spectrum which is no worse than a similar unit of equipment which is
> operating satisfactori­ly.
>
> [2]{.underline}. [Vibration Analysis of New Equipment]{.underline}.
> For all large or critical pieces of equipment assembled and run at the
> factory prior to shipment, a narrowband vibration spectrum should be
> acquired at the locations listed in clause 10 below while the
> equipment is undergoing this factory performance testing. A baseline
> or reference spectrum shall be retained for comparison with the
> post-installation vibration check.
>
> Equipment failing the vibration criteria shall be rejected prior to
> shipment.
>
> Tests under the following situations shall be performed if the
> equipment fails the initial test and/or if problems are encountered
> following installation:
>
> • Motor cold and uncoupled.
>
> • Motor hot and uncoupled.
>
> • Motor and machine coupled, unloaded and cold.
>
> • Motor and machine coupled, unloaded and hot.
>
> • Motor and machine coupled, loaded and cold.
>
> • Motor and machine coupled, loaded and hot.
>
> A significant change in the vibration signature could indicate a
> problem with thermal distortion and/or bearing overloading due to
> failure of one of the bearings to float.
>
> [3]{.underline}. [Vibration Criteria for Electric Motors]{.underline}
>
> [a]{.underline}. [General]{.underline}. All motor vibration spectra
> shall be analyzed at the following forcing frequencies:
>
> • One times running speed (1X) for imbalance.
>
> • Two times running speed (2X) for misalignment.
>
> • Multiples of running speed (NX) for looseness, resonance, plain
>
> bearing defects.
>
> • Electric line frequency and harmonics (60 or 120 Hz for AC motors)
> for stator and rotor problems.
>
> • The following is a list of rolling element bearing frequencies:
>
> --- Outer race defect frequency
>
> --- Inner race defect frequency
>
> --- Ball defect (ball spin frequency)
>
> --- Fundamental train frequency
>
> • Plain or journal bearings indicate faults at harmonics of running
> speed and at the frequency corresponding to 0.4-0.5 of running speed.
>
> • Other sources of vibration in motors are dependent on the number of
> motor rotor bars and stator slots, the number of cooling fan blades,
> the number of commutator bars and brushes, and on the SCR firing
> frequen­cies for variable speed motors.
>
> • Broken rotor bars will often produce sidebands spaced at two times
> the slip frequency. The presence of broken rotor bars can be confirmed
> through the use of electrical testing.
>
> [b]{.underline}. [Balance]{.underline}. The vibration criteria listed
> in Table 7.2-a. below are for the vibration amplitude at the
> fundamental rotational frequency or one times running speed (1X). This
> is a narrowband limit. An overall reading is not acceptable.
