4. QUALITY ASSURANCE PROVISIONS.

4.1 First Article acceptance and tests.

4.1.1 Acceptance. Prior to all tests, the first article containers shall be physically examined for compliance with the documents listed on DL8864811 and DL8864861 respectively. Approval shall consist of a visual inspection of the characteristics and measurement of the component parts and complete container to ensure compliance with the drawings. Measuring instruments sufficient to verify drawing tolerances shall be used. Inspection shall include the availability of instruments sufficient to verify drawing tolerances. Approval shall include the examination of inspection records, material certifications and the comparison of these documents with the item(s) they describe. The Government reserves the right to terminate the inspection and reject the first article sample upon failure of any component, assembly, or test specimen in the preproduction sample to comply with any requirement defined in this specification.

4.1.2 Item interface/fit test. This test shall be conducted by bringing together the container and the intended load. The items shall be placed in position in the containers. The container shall be closed in its normal shipping condition, and secured by fastening all latches. Care shall be exercised to assure that both the container and the load are representative of the final configuration and that normal dimensional variations are considered. Interface dimensions may be dimensionally inspected to verify conformance to drawing requirements. The container shall meet the requirements of 3.2.1.3.1 and 3.2.1.3.2. After tests and measurements are complete, the container shall then be unloaded.

4.1.4 Gasket strength. The gasket shall be subjected to a 20-pound force pull perpendicular to the plane of the splice to verify conformance to 3.2.1.4.

4.1.5 Leak test.

4.1.5.1 Pneumatic pressure technique. The air in the container is pressurized and then the container is observed to detect leaks. A leak is defined as any opening in a container that allows air to escape or permits air to enter. When a container is found to leak, submersion in water, a portable ultra-sonic leak detector, or application of soapy water may be used to locate the leak(s). If leaks are detected the container shall be repaired to eliminate the leaks and then re-tested for verification.

4.1.5.2 Apparatus. A supply of compressed air, pressure gage and fittings, and either a vessel in which the specimen can be submerged in water, a quantity of bubble-supporting liquid, or ultra-sonic leak detector are required to perform this test. Pressure measurement devices may include a water manometer or digital manometer with an accuracy not less than 0.005 psig. The digital manometer, when used, shall be calibrated and certified.

4.1.5.3 Conditioning. No special conditioning of the containers is required; the test shall be performed in normal room condition (70 10 F). The pressure test is very sensitive to heat and cold fluctuations; the temperature shall not be allowed to fluctuate more than 2 during the test.

4.1.5.4 Procedure. The container shall be prepared for the test by sealing all breathing devices and inserting suitable pressurizing fittings and gages. The fittings and gages shall not cause adverse effects on the serviceability of the container. The container shall be closed and sealed, as it would be in service. The test shall be conducted by raising the internal pressure so that the desired pressure differential of 1.0 +0.25/-0.0 psig is obtained. After pressurization, the container shall be left undisturbed for not less than 15 minutes for temperature and pressure stabilization. The pressure shall be monitored for not less than 30 minutes after stabilization. Pressure leakage of more than 0.05 psig in 60 minutes shall be cause for rejection. If there is pressure loss of less than

0.025 psig within 30 minutes, after stabilization, the test may be terminated as successful. The container shall meet the requirements of 3.2.1.2

4.2 Production quality conformance inspection and test.

4.2.1 Inspection. The contractor's inspection system shall be sufficient to ensure that parts and materials submitted conform to the requirements of each design’s DL. The contractor is responsible for furnishing articles that meet all the requirements of drawings and specifications included in this contract. Production shall be performed under controlled conditions. The procedures used for process control and inspection are at the option of the contractor, provided objective, documented evidence is maintained and made available upon request by the Government.
