23、ility for inspection. Unless otherwise specified in the 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 fac

24、ilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Govern- ment. 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

25、 conform to prescribed requirements. 4.1.1 Responsibility 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 requ

26、irements in the specification shall not relieve the 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

27、 material, either indicated or actual, nor does it commit the Government to acceptance of defective mterial, 4.1.2 Test report. When specified in the contract (see 6.2. i), the contractor shall furnish test reports to the procuring activity. 4.2 Classification of inspections. The inspection requirem

28、ents specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection (see 4.5). 4.3 Inspection conditions.

29、inspection shall be performed after award of contract and prior to production by a facility designated in the contract or order (see 6.2.1). First article inspection shall be performed on sample units which have been produced using the same materials, equipment, processes and procedures as will be u

30、sed in regular production. 4.4.1 Sample size. The first article sample shall consist of 10 pounds of propellant grains. 4.4.2 Inspection routine. The sample shall undergo the tests specified in 4.6 and any additional tests as specified by the procuring activity. 4.4.3 Failures. Failure of the propel

31、lant grains to meet any of the above requirements shall be cause for first article rejection. 4.5 Quality conformance inspection. Quality conformance inspection shall consist of the tests specified in 4.6. Failure of any sample to conform to any requirement specified herein shall be cause for reject

36、ation. The percent by weight of graphite shall be determined in accordance with MIL-STD-286, method 309.1.2. 4.6.4 Moisture determination. The moisture content shall be determined in accordance with MIL-STD-286, method 103.1.3. 4,6.5 Specific gravity determination. Specific gravity shall be determin

37、ed in accordance with OD 40816. 4.6.6 Stability. Stability shall be determined in accordance with MIL-STD-286, method 406.1.2. 4.6.6.1 Alternate method. Method 404.1.2 (120“ C heat test) of MIL-STD-286 may be used to deter- mine stability. 4.6.7 Delivered impetus test. The delivered impetus shall be

38、 determined as specified in MIL-STD-286, Method 801.1 for closed bomb method and IHSP 85-208 for computer determination. 4.6.8 Visual examination.
