Residual radioactivity of the holders shall not be detectable a
18、bove normal background when tested as specified in 4.3. 3.3 Recovered materials. Unless otherwise specified herein, all equipment, material, and articles incorporated in the products covered by this specification shall be new and may be fabricated using materials produced from recovered materials to
19、 the maximum extent practicable without jeopardizing the intended use. The term “recovered materials means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials. None of the above shall be interpreted
20、 to mean that the use of used or rebuilt products is allowed under this specification unless otherwise specifically specified. 3.4 Workmanship. The holders shall be uniform in quality and condition; clean, sound, smooth, and free from buckles, blisters and other injurious defects within the limits c
21、onsistent with best commercial practice. Discoloration due to heat treatment shall not be cause for rejection. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all ins
22、pection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Governmen
23、t. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of section
24、s 3 and 5. The inspection set forth in this specificatioc shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or suppl
25、ies submitted to the Government for acceptance comply with all requirements of the contract (see 6.3). Sampling inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective mate
26、rial, either indicated or actual, nor does it commit the Government to accept defective material. 4.2 Samplinq. Sampling for radioactivity inspection, visual and dimensional examinations, and packaging inspections shall be in accordance with table I. The lot size is defined as the quantity of items

The residual radioactivity level of the holders shall be measured to determine that the activity level
30、 is not detectable above normal background radiation as follows. Each selected sample shall contain less than 1.0 picocurie of equivalent strontium - 90 radioactivity (at the 95 percent confidence level) when individually counted using a low background beta - proportional counter which has been cali
31、brated with a strontium - 90 standard. 4.4 Visual and dimensional examinations. Visual and dimensional exami- nations shall be made in accordance with table I to determine the quality of dimensions and finish as specified on figures 1 and 2, and in 3.4. 4.5 Inspection of packaging. Sample packages a
