II. Components
Parts and assemblies to be reconditioned under Section 1800 Low Voltage Contactors and Relays include but are not limited to:

• Coil
• Contacts
• Wiring
• Terminals
• Legend
• Escutcheon
• Armature
• Connector
• Nameplate
• Chassis
• Base or mounting plate

III. Standards
The PEARL Section 1800 Low Voltage Contactors and Relays Proposed Standard begins with the definition of the term "Reconditioning" as "the process of returning electrical equipment to safe and reliable operating condition based upon the design of the original manufacturer at the time of manufacturing." This is followed by reference tables used to calculate test results and tolerances and the necessary test equipment required by the low voltage contactors and relays standards. The low voltage contactors and relays standards continues with a "Recondition Evaluation," which is a detailed inspection of all parts of the low voltage contactors and relays, including but not limited to the components listed above.

IV. Testing and Inspection
Section I for PEARL Section 1800 Low Voltage Contactors and Relays begins with reference table identification and identification of the test equipment necessary to complete the standard, including one or more:

1. Insulation Resistance Test Set (Megohmeter) 500 Vdc minimum
2. AC Voltage Supply
3. Multimeter
4. Timer with a AC voltage applied START Circuit

Section II Recondition Evaluation-Inspection and Testing identifies each component and assembly part that must be inspected to determine the components viability and scope of reconditioning required to bring the component back to original operating condition. Results and notes from the pre-reconditioning inspection and test are recorded in the PEARL Reconditioning Evaluation and Test forms that accompany each respective standard.

V. Reconditioning
Section III Reconditioning Procedures describes how to recondition each component and assembly, beginning with the disassembly of the motor control unit down to its major subassemblies. Reconditioning for low voltage contactor and relay includes: " Disassembly " Cleaning " Drying " Deoxidizing " Removal of corrosion " Degreasing " Plating " Painting " Lubricating " Adjusting

Assembly of the reconditioned components and subassemblies is followed by final inspection and testing. As with all testing, inspection, and reconditioning operations, final inspection and test results are recorded onto the Evaluation and Test forms included with the standard. If a PEARL certified technician follows the reconditioning standard, the low voltage contactor or relay assembly is eligible for a Blue PEARL Reconditioned Quality Seal.

* A proposed standard is one which as been created and offered to technical committee participants for vetting. A proposed standard may go through any number of drafts, revisions and changes before being accepted. All proposed PEARL Standards are only in their first draft form currently and are NOT yet recommended for use in the field.
