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.

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.

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

37、en chambers of not more than 5 minutes. Each motor shall undergo a total of three cycles (see 6.4.6). Conditioning for one group shall begin and end at -40F and the other group shall begin and end at 140F. After temperature cycling, the grain shall be returned to ambient tem- perature and radiograph
