New Motor Dedication
All critical characteristics testing will be performed by United Controls International, an outside testing facility, the motor manufacturer, or motor repair/testing facility under the direct control of UCI. Based on the safety-Related function of the motor, the critical characteristics have been determined to be:

Markings and identification (i.e. nameplate data)
Materials/Physical Properties or Appearance (i.e. enclosure material, shaft material, weight, etc.)
Dimensions
Mechanical Functional Attributes (i.e. full-load speed, full-load horsepower, speed-torque characteristics, acceleration time, bearing vibration, bearing temperature, etc.)
Electrical Functional Attributes (i.e. insulation integrity, winding resistance, full load amps, etc.)
Functional Acceptance Testing Method. Reasonable assurance that the motor possess these characteristics shall be verified in accordance with the requirements of CGDS-226.
In addition, when parts and/or materials are necessary to provide reasonable assurance for proper functioning of the motor, technical evaluations will be performed in accordance with the requirements of UCI procedure QCP-3.4. Dedication of rewind materials will be performed in accordance with CGDS-179.
