QUALITY
8、 ASSURANCE PROVISIONS 4.1 Responsibilitv for inspection.- Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified, the supplier may utilize his own facilities or an
9、y commercial laboratory acceptable to the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 4.1.1 General provisions.- The comp
10、onent and subassembly in- spection requirements of MIL-F-13926 form a part of the quality assurance provisions of this specification. Definitions of inspection terms shall be as listed in MIL-STD-109. 4.2 Initial production test.- Initial production test samples shall be submitted in accordance with
11、 contract requirements. Unless otherwise specified in the contract, samples shall be the first two production units and shall have been manufactured using the same ma- terials, processes, and procedures as will be used in regular produc- tion. Initial production testing shall be in accordance with 4
12、.3, 4.4, and 4.6 and shall be witnessed by the Government representative for all examinations and tests. The Government reserves the right to conduct any or all examinations or tests as may be deemed necessary. 4.2.1 Initial production sample failure.- Should one unit fail to meet the initial produc
13、tion testing specified in 4.2, the contractor shall cease those operations which are causing the rejection and make the necessary corrections thereto. When corrections in the process or controls have been made, two additional (new) production models shall be submitted in accordance with 4.2. Provide

Examinations and tests related to Section 3 herein shall be performed on a single defect (individual characteristic) basis in acc
16、ordance with MIL-STD-105 and the sampling plans specified in Tables I, II, and III herein. Examinations and tests for packaging, packing, and marking shall be in accordance with MIL-P-14232 and Section 5 herein. The tabulated classification of defects shall constitute the minimum inspection to be pe
17、rformed by the supplier prior to Government acceptance or rejection by lot.

23、 been approved (see 4.3 3) . 4.5 Inspection equipment. - Except as otherwise provided for by the contract, the contractor shall supply and maintain inspection equip- ment in accordance with the applicable requirements of MIL-1-45607. 4.5.1 Government furnished inspection equipment.- Where the contra
24、ct provides for Government furnished test equipment, supply and maintenance of test equipment shall be in accordance with the applicable requirements specified in MIL-1-45607. 4.5.2 Contractor furnished inspection equipment. 4.5.2.1 Government design.- Unless otherwise specified in the contract, all
25、 inspection equipment specified by the contract shall be supplied by the contractor in accordance with 4.5. 4.5.2.2 Contractor design.- The contractor shall design and supply inspection equipment compatible with the “Test methods and procedures“ specified in 4.6 of this specification and with the co
26、mponent inspection procedures specified in “Examination“ and “Test facilities“ requirements of MIL-F-13926. Since tolerance of test equipment is normally considered to be within 10% of the product tolerance for which it is intended, this inherent error in the test equipment design must be considered
27、 as part of the prescribed product tolerance limit. Thus, concept, construction, materials, dimensions, and tolerances used in the design of test equip- ment shall be so selected and controlled as to insure that the test equipment will reliably indicate acceptability of a product which does not exce
28、ed 90% of the prescribed tolerance limit, and permit positive rejection when non-conforming. Construction shall be such as to facili- tate routine calibration of test equipment.
