Using the contractors written quality assurance proce- dure, this detailed specificatiox, the applica- ble drawings, and other contractual docu- ments as a guide, the Government inspector shall verify, at unscheduled int
6、ervals, all quality assurance operations performed by the contractor. Verification will be performed to the extent necessary to assure compliance with the contractual requirements. Severity of Government inspection of individual char- acteristics will be directly related to the ser- iousness of the
7、classification assigned. In no instance will a characteristic classified “Crit- ical” be accepted solely on the basis of the contractors records. 4.2 First article inspection. 4.2.1 Submission. The contractor shall sub- mit a first article quantity to a Government- approved facility as designated by
8、 the Con- tracting Officer (see 6.1) for evaluation in accordance with provisions of 4.2.2. The first article sample shall consist of the following: a. Twenty-five (25) of each component. b. Two hundred (200) loaded assemblies. All components and completed assemblies shall have been produced by the
9、contractor or furnished by a supplier and which have been manufactured using the same produc- tion processes, procedures and equipment as will be used in fulfilling the contract. All parts and materials, including packaging and packing, shall be obtained from the same sources of supply as will be us
10、ed in regular production. The sample shall be accompanied by certificates of conformance for materials. A first article sample, or portion thereof, as directed by the Contracting Officer, shall also be submitted whenever there is a lapse in production for a period in excess of 90 days or whenever a
11、change occurs in manufactur- ing process, material used, drawing, specifi- cation, or source of supply as to significantly affect product uniformity as determined by the Government. Prior to submission, the contractor shall inspect the sample to the -3 -. Provided by IHSNot for ResaleNo reproduction

A sample containing known defects will not be submitted
13、unless specifically author- ized by the Contracting Officer. 4.2.2 Inspections to be performed. Com- ponents and completed assemblies will be subjected by the Government to all the exam- inations or tests specified in 4.3.2 and 4.3.3 of this specification, and any or all require- menta of the applic
14、able dragngs. In addi- tion, the following test shall be performed. Thereafter, testing shall be as specified in 4.3.2 and 4.3.3. 4.2.2.1 Functioning (see 3.4). The two hundred (ZOO) Ioaded relay assemblies shall be subjected to the functioning test as speci- fied in 4.4.2 using equipment in accorda
15、nce with 4.3.4. 4.2.3 Rejection. If any component or relay assembly fails to comply with any of the ap- plicable requirements, the first article sample shall be rejected. The Government reserves the right to terminate its inspection upon any failure of a component or relay assembly in the sample to
16、comply with any of the stated requirements. In the event of rejec- tion, the Government reserves the right to require the contractor to take corrective ac- tion and submit a new first article sample or portion thereof. Until a first article sample is accepted, the contractor is in no way authorized
17、by the Government to resume reg- ular production unless otherwise directed by the Contracting Officer. 4.3 Inspection provisions. 4.3.1 Lot formation. The term “Lot” as used throughout this specification refers to an in- spection lot, which is defined as an essentially homogeneous collection of unit
18、s of product from which a representative sample is drawn and inspected to determine conformance of the lot with applicable requirements. The samnle selected shall represent only that 4 f quantity of units from which the sample was drawn and shall not be construed to rep- resent any prior or subseque
19、nt quantities - presented or inspection. Homogeneity shall be considered to exist provided the lot has been produced by one manufacturer, in one unchanged process, in accordance with the same drawing, same drawing revisibn, same specification and same specification revision. Changes to the process,
20、specification or draw- ing not affecting safety, performance, inter- changeability, or storage, as determined by the Government, shall not be deemed to alter the homogeneity of the lot. The lot shall con- tain (a) Parts of one lot interfix number from manufacturer. (b) Lead azide from not more than
21、one lot. The inspection lot shall comply with MIL STD-105 and shall be numbered in accord- ance with MIGSTD-1168: Unless otherwise approved by the Contracting Officer, the in- spection lot size of end items deliverable un- der the contract shall be not less than the smallest weekly estimate of quant
22、ities con- tractually scheduled for production during the contract period, nor more than the Iarg- est monthly quantity contractually scheduled for delivery during the contract period. In- spection lots for components of subassem- blies, other than the items of delivery, shall be homogeneous and of
23、a size mutually con- venient to both the contractor and the Gov- ernment inspector. 1.3.2 Examination. Sampling plans and procedures for the following classifications of defects shall be in accordance with MIL- STD-105 (ABGSTD-105), except that, in- spection for Critical defects shall be 100 per- ce
24、nt. Contractors sampling plans, if used. shall be approved by the Government, and shall provide, as a minimum, the protection afforded the Government by the sampling plans in MIGSTD-105 (ABCSTD-105). Continuous sampling plans in accordance with MIGSTD-1235 may be used if ap- 1 _. Provided by IHSNot
