    3. Destination
    4. Contract Number
    5. Length of cable on reel
    6. Voltage rating
    7. Description of cable
    8. Reel number
    9. Shipping weight of cable and reel
2.09   Factory Tests and Reports
   
  1. General:
    1. Complete factory tests, in accordance with the applicable standards listed in Section 1.2 and the following, shall be performed on all cables and terminations prior to shipment. Prior to start of fabrication, the Manufacturer shall submit for the Owner’s approval a complete listing of all routine tests and tests to be performed or verified with certification documents. The listing should clearly specify the method of testing and sampling. The cable shall not be shipped unless results of tests show compliance with all requirements of this Specification. The Owner reserves the right to select samples and witness all tests. The Manufacturer shall provide written notification to the Owner at least 3 weeks in advance of the test date. The notice shall include an outline of the procedures used in performance of the tests.
    2. All factory tests prescribed by this Specification shall be made at the expense of the Manufacturer. All samples are to be furnished by the Manufacturer. The Manufacturer shall furnish certified test reports for all tests performed.
    3. The Manufacturer shall maintain a file of all test reports which shall be fully auditable and accessible to the Owner for a minimum of one year. Upon completion of testing, submit certified report attesting that each test was performed in accordance with the approved test procedures. The report for each test shall include the date of performance and the name of the person in charge of the test.
    4. Manufacturer’s tests, as well as all tests required by the applicable standards, shall be performed. Tests listed below are representative only and do not constitute all the required tests.
  2. Type Test: Perform type tests on samples of cables in accordance with applicable standards and provide test certificates. In lieu of type tests, Owner may at its own discretion waive type tests, provided Manufacturer furnishes certification of type tests on identical cables.
  3. Routine Tests:
    1. All routine tests shall be performed in accordance with the procedures specified in the applicable sections of the latest revisions of the specified UL standards.
    2. The following routine tests are to be performed on each reel of completed cable.
