QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the con- tractor i
16、s 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 requirements specified herein, unless disapprov
17、ed 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 conform to prescribed requirements. o 3.5 4.6.4 3.3 4.6.1 3.4 4.6.2 4.1.1 Responsibility for complian
18、ce. All items must meet all requirements of sections 3 and 5. The inspection 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 contractor of the re
19、sponsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling in quality conformance does not autho- rize submission of known defective material, either indicated or actual, nor does it commit the Government t
20、o 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 specified (see 6.2. i), all in
21、spections shall be performed as specified in the applicable test method of 4.6. 0 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 6.2.1 and 6.2.2). First article inspectio
22、n shall be performed on sample units which have been produced using the same materials, equipment, processes and procedures as will be used in production. All parts and materials, including packaging and packing shall be the same as used for production and shall be from the intended sources of suppl
23、y. 4.4.1 Sample size. The first article sample shall consist of 100 propellant grains. 4.4.2 Inspection routine. First article inspection shall consist of the tests specified in 4.6. AI1 100 grains shall be subjected to the tests with the exception of temperature cycling. Only four grains shall unde
24、rgo temperature cycling. 4.4.3 Failure. Failure of the sample to meet the requirements of this specification shall be cause for rejection of the first article sample. 4.5 Quality conformance inspection. Quality conformance inspection shall consist of the tests specified in table II (see 6.2.2). TABL

Unless otherwise specified (see 6.2.1), the production
26、 lot size shall be limited only by the number of grains that can be manufactured from a single lot of propellant (carpet rolls). The term “lot” as referred to in this specification shall mean prduction lot (see.6.4.5); Lots shall be numbered in accor- dance with MIL-STD-1168. 4.5.2 Sampling. 4.5.2.1

28、acteristics and an AQL of 2.5 percent for minor characteristics. 4.5.2.2 For destructive tests. The ballistic acceptance sample for the propellant grain lot shall be select ed and evaluated in accordance with MIL-STD-414, inspection level III, variability unknown, standard devi- ation method, with a
29、n AQL of l .O percent.

The characteristics verified by the tests and examinations herein
30、are classified as critical, major, or minor in accordance with DOD-STD-2101. Requirements that verify critical characteristics are identified by the symbol (C) and major characteristics by the symbol (M). The number following the classification symbol indicates the serial number of the requirement.

All measurements shall be made with instruments and systems with a total sys- tem accuracy, reproducibility, and frequency response that has been approved by the procuring acitivity. Calibration records of all test equipment shall be maintained and
36、made available to the procuring activity upon request. 4.6.3 Temperature cycling. The propellant grains shall be equally divided into two groups with each group subjected to alternate conditioning chambers at - 40F and 140”F, remaining in each chamber not less than 8 hours with a transfer time betwe
