18、for inspection. Unless otherwise specified iii the contract or purchase order, the supplier is responsible for the perfonaance of all inspection requirements as specified herein. Except as otherwise specified iri the contract or order, the supplier may use his own or any other facilities suitable fo
19、r the performance oi the inspectioil requirements specified herein, unless disapproved by the Government.

21、 forth in this specification shall become a part of the- contractors overall iiispection systei.1 or quality program. The absence or any inspection requirenents in the specification shall not relieve the coiitractor oi the responsibility or ensuririy that all products or supplies submitted to the Go
22、vernment for acceptance cornply witli all requirements oi the contract. Sampling inspection, as part of kianufacturing operations, is an acceptable practice to ascertaiil conformance to requirements, however, this does not authorize submission of known defective naterial, either indicated or actual,
23、 nor does it cormit the Government to accept defective naterial. 4.2 Classification OE inspections. The inspection reyuireineiits specified herein are classified as follows: a. First article inspection (see 4.3) b. Quality conforrnance inspection (see 4.4) 4.3 First article inspection. 4.3.1 Subuiss
24、ion. Wien the contract requires first article inspection, the contractor shall subnit two consecutively produced concertina subassemblies to the testing facility designated in the invitation for bids or request for proposal. 4.3.2 Iiispection aiid testing to be performed. The first article irispecti
25、oii sample shall be inspected for the defects specified in 4.4.2.1, using inspection nethods contained therein, and for all the requirements of Section 3. The test: requirements of Section 3 are listed in Table II and the concertina subassemblies shall be tested usiriy tlie methods of inspection spe
26、cified in 4.5. Inspection and testing shall be performed with tlie acceptance inspection equipment specified in 4.4.4. Should aiiy iten fail to comply with any of the applicable requirements, the first article samples shall be rejected. The Government reserves the right to terninate its inspections
27、upon any failure ol: the first article samples to conply with the stated reyuirenents. This series of tests, listed in Table II, are iiot considered destruct ive. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-63959 81 999990b 0489572 b Test

A lot or batch and its formation, size and presentation is described in MIL-A-48078. Accordingly, a lot shall mean an inspection lot, and a
29、batch shall mean an inspection batch for the purposes of this specification. The manner in which each inspection lot or batch is to be presented and identified by the contractor shall be designated or approved by the Government representative. 4.4.2 Product inspection examination. A sample shall be
30、selected at random from each inspection lot in accordance with Table III for inspection of majo; and minor defects, as applica- ble. If one or more defects is found in the sample selected for either major or minor inspections, the lot shall be rejected. The sequence of inspections for the classifica
31、tion of defects need not be followed so long as all the defect inspection are performed. The term, “SMTE,“ where used, shall mean any standard measuring and test equipment suitable for the test being performed. TABLE III. Inspection lot samplina.
