QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the

21、contract or purchase order, the con- tractor is responsible for the performance of all inspection requirements 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 r

22、equirements specified herein, unless disapproved by the Govern- ment. The Government reserves the right to performany of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed re- quirements. 1 ) 4.1.1 Responsi

23、bility for compliance. All items must meet all requirements of sections 3 and 5. The in- spection set forth in this specification 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

24、 con- tractor of the responsibility of assuring that all products or supplies submitted to the Government for ac- ceptance comply with all requirements of the contract. Sampling in quality conformance does not authorize submission of known defective material, either indicated or actual, nor does it

25、commit the Government to acceptance of defective material. 4.2 Classification of inspections. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection (see 4.5). 4.3 Inspection conditions. Unless otherwise specifi

26、ed in the contract(see 6.2), all inspections shall be per- formed as specified in the applicable test method of 4.6. 4.4 First article inspection. First article inspection shall be performed after award of contract and prior to production by a facility designated in the contract or order (see 6.2).

27、First article inspection shall be per- formed on sample units-which have been produced using the same materials, equipment, processes and proce- dures as will be used in regular production. All parts and materials, including packaging and packing shall be the same as used for regular production and

28、shall be from the intended sources of supply. 4.4.1 Sample size. The first article sample shall consist of 70 delay cartridges. 4.4.2 Inspection routine. Sixty cartridges shall be expended in the tests listed below and 10 shall be re- tained for investigative purposes. Cartridges shall undergo the f

29、ollowing tests as prescribed in MIL-D-21625: 40-foot drop test (6); 14-day temperature and humidity cycling (18); vibration (12); low temperature (12); and high temperature (12). The number in parentheses denotes the number of cartridges allocated for each test. These cartridges (with the exception

30、of the 40-foot drop test sample), shall b.e fired in the test device of 4.6.6. The failure of any cartridge to meet the acceptance requirements as stated above shall be cause for rejection of the first article sample. Any quantity production prior to notification by the contracting agency of first a

31、rticle sample acceptability shall be at the contractors risk. 4.4.3 Failure. Failure of the sample to meet the requirements of 3.2 through 3.8 shall be cause for rejec- e tion of the first article sample. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS

Tests and examinations that verify critical characteristics are identified by the symbol (C) and major chara

37、cteristics by the symbol (M). The number following the classification symbol indicates the serial number of the test or examination, Tests and examinations which are not annotated with a classification code are classified minor, 4.6 Tests, 4,6,1 Ignition device verification. When ignition devices ar

38、e supplied as Government furnished material (GFM), certification of acceptability shall accompany the shipment. This does not relieve the contractor from any responsibility or quality, inspections or tests specified, 4.6.2 Radiographic examination. 4.6.2.1 Ignition devices. Prior to assembly, ail ig

39、nition devices shall be radiographically examined in ac- cordance with MIL-STD-453. Ignition devices having any of the defects specified in 3.4.1.1 shall be reject- ed. The ignition devices shall be mounted on boards or trays, preferably grooved, with the cup side perpen- dicular to the rays, for th

40、e most revealing exposure. Pressure sensitive tape may be used as an aid in positioning the ignition devices. The X-ray negatives shall be identified by item nomenclature and lot number. Ignition devices shall be left mounted to the boards or trays until after the X-rays have been reviewed and defec

41、ts identified to facilitate removal of defects. After screening, the X-rays with defectives identified, shall be forwarded to the engineering agency designated in the contract (see 6.2). 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-BL730A

43、 tridges shall be positioned for the most revealing exposure with the long axis of each assembly perpendicu- lar to the rays of the X-ray machine, All cartridges shall be identified with serial numbers prior to examination. The serial numbers shall be in consecutive order and each radiograph shall c

44、arry a permanent identification of the cartridges displayed thereon. The radiograph identification shall include item nomenclature,the com- plete lot number assigned to that lot, and the span of serial numbers displayed. Each serial number shall be marked on the case by pen or ink stamp. Any missing

45、 serial numbers are to be identified on the X-rays. Radiographs of the entire production lot shall accompany the ballistic sample to the activity conducting the production lot acceptance tests (see 6.2).

Cartridges which exhibit a leak rate in excess of cc per second of air at a pressure differential of 1 +- 0.1 atmosphere sha

48、ll be considered defective. Cartridges of the first article sample which exhibit a leakage defect shall be rejected. If one or more cartridges of the production lot sample exhibits a leakage defect, then a 100 percent leak test of the lot being tested shall be conducted. Cartridges which exhibit a l

49、eak rate in excess of that specified above shall be rejected. 4.6.6 Ballistic test. The number of cartridges selected from each production lot for the ballistic test shall be in accordance with table II. The cartridges shall be conditioned at +70 f 5OF for a minimum of 6 hours and fired in the test fixture, DL2838169.
