QUALITY ASSURANCE PROVISIONS

General The COTR shall monitor the installation of the system. The system delivery dates shall not be extended because of work stoppages caused by unacceptable practices and/or test failures. For all inspections and tests, the Contractor shall provide all test apparatus (i.e., tape measures, levels, calipers, micrometers, stop watches). All test apparatus will be returned to Contractor upon completion of all tests. The Government will provide all test loads. The Contractor shall be responsible for loading and unloading all test loads and performing all inspections and tests. The Contractor shall provide a knowledgeable and authoritative representative on site during the entire acceptance tests.

Acceptance Tests Three tests must be successfully completed prior to the Government accepting the system. These tests are the system checkout test, the quality conformance test, and the reliability demonstration test.

System checkout test Upon completion of installation, the Contractor using loads of the type specified herein and in the appendices shall check out the system. The Contractor shall inspect the system to assure that the system meets all the requirements of 4.3.1. The Contractor shall also test the system in accordance with the test defined in 4.3.2. All inspections and tests shall be repeated until all modifications and/or adjustments are complete and the system passes all inspections and tests. The Contractor shall submit to the Contracting Officer written certification that the system has passed the requirements of this paragraph. The COTR will schedule the quality conformance test to start within 10 days following the receipt of the written certification from the Contractor.

Quality conformance test As part of the quality conformance test, the Contractor shall provide written certification that the requirements listed in 4.3.3. have been met. This certification is required on or before the start of the quality conformance test. The Contractor, in the presence of the COTR, shall inspect the system to confirm that the system meets all the requirements of 4.3.1. The Contractor, in the presence of the COTR, shall also test the system in accordance with the test defined in 4.3.2. Upon successful completion of all tests and inspections and the receipt of all certifications, the reliability demonstration shall start.

Reliability demonstration test After successful completion of the quality conformance test, each component of the system shall demonstrate a reliability and availability greater than that listed in the reliability/availability table in 3.4.1.1. In addition, all static components shall demonstrate compliance with the requirements of the purchase description (PD). The test period shall be the 30 calendar days immediately following the successful completion of the quality conformance test. If the system does not demonstrate the required reliability and availability or compliance with the PD, the test will be restarted from the beginning after the Contractor has taken corrective action. The Contractor shall be allowed to restart the reliability demonstration test a maximum of 2 times. If the system fails to pass the reliability demonstration within 3 attempts, then the system shall be rejected.

Inspections, tests, and certifications This section defines all inspections and tests that must be completed as part of the system checkout test and repeated at the quality conformance test. This section also includes a list of all certifications that must be received from the Contractor on or before the start of the quality conformance test. The Contractor may add to this list, or question any requirement, by sending a letter to the Contracting Officer prior to the acceptance tests. The COTR will classify all deficiencies encountered into one of the defect classification listed below. Any critical or major defect found shall be cause for rejection of the system. Any combination of two or more minor defects shall leave the rejection of the system at the discretion of the COTR.

Critical Defect - A defect that judgment and experience indicate is likely to result in hazardous or unsafe conditions for individuals using, maintaining, working near, or depending upon the equipment.

Major Defect - A defect other than critical that is likely to result in failure, or reduce materially the system for its intended purpose.

Minor Defect - A defect that is not likely to reduce materially the usability of the system for its intended purpose, or is a departure from established standards having little bearing on the effective use or operation of the system.

Inspections The system shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of the cover purchase description (and associate appendices, if applicable).
