3.3.5. UN performance oriented packaging (POP) tests. Unless otherwise specified in the contract or purchase order, the containers shall be subjected to the design qualification testing prescribed by 49 CFR, Subpart M, 178.600. Unless otherwise specified in the contract or purchase order, the test sample specified by the appropriate test section of 49 CFR Subpart M shall be supplied to the Air Force Packaging Technology and Engineering Facility (AFPTEF) and subjected to performance testing as called out in 4.2. Periodic retesting shall be completed every 24 months in accordance with 49 CFR, Subpart M, 178.601(e). AFPTEF shall prepare a written report at the completion of testing.

4. QUALITY ASSURANCE PROVISIONS.

4.1. First article (FA). Unless the first article is waived or otherwise specified in the contract or purchase order, one preproduction sample (of each container type), hereinafter referred to as first article, shall be inspected and tested prior to regular production. The first article shall be fully representative of those proposed for production and demonstrate the adequacy and suitability of the contractor’s processes and procedures in complying with the requirements set forth by this specification. Unless otherwise specified, all tests shall be performed at ambient temperature of 70° ± 20° Fahrenheit with ambient humidity.

4.1.1. Inspection. Prior to all tests, the first article containers shall be physically examined for compliance with documents listed on the containers drawing package. 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. 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.

CUI

4.1.2. Leak Test.

4.1.2.1. 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.

4.1.2.2. 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.

4.1.2.3. Conditioning. No special conditioning of the containers is required; the test shall be performed at ambient conditions (70° ± 20° 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.

4.1.2.4. 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 the test may be terminated as successful. The container shall meet the requirements of 3.2.1.2.

4.1.3. Item fit test. Each container will be fit checked. Each container shall be loaded with generic asset representative items (furnished by the government).

The items shall be loaded into the container isolation system. The cover shall be placed on the base assembly and latched securely to verify fit.

4.2. UN performance oriented packaging (POP) testing. Unless exempted per paragraph 3.3.5, at the start of each new production contract, the container shall successfully pass the drop test, stacking test, and vibration test in accordance with the procedures of 49 CFR 178.603, 178.606, and 178.608, respectively. The
