Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the

32、contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed

33、necessary to assure supplies and services conform to prescribed requirements. Unless otherwise specified herein or in the contract, the provisions of MIL-A-48078 shall apply and are hereby made a part of this detail specification. 4.1.1 Responsibility for compliance. All items must meet all requirem

34、ents of section 3 and 5. The inspections 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 responsibility of assuring that all pr

The following tests shall be performed in accordance with the provisions of Table I and 4.4

43、. 4.4.3.1 Mechanical properties. 4.4.3.1.1 Hardness (forqinqs) . See 4.4.1.1. In order to determine the body forgings that will be used for the tension test, the base of each body forging in the forging lot, after heat treatment and prior to machining, shall be subjected to a hardness test with a Ro

44、ckwell Hardness Tester or by any other method of hardness testing approved by the procuring activity. 4.4.3.1.2 Hardness (cold shapinqs). See 4.4.1.2 In order to determine the bodies formed by cold shaping that will be used for the tension test, the base of 25 bodies in the cold shaping lot, after s

45、tress relief and prior to machining, shall be subjected to a hardness test with a Rockwell Hardness Tester or by any other method of hardness testing approved by the procuring activity. See 4.4.5.3.1. 4.4.3.1.3 Tensile test. From 4.4.3.1.1 and 4.4.3.1.2, two bodies, one of the softest and one of the

46、 hardest from each forging or cold shaping lot (see 4.4.1) shall be subjected to this test to determine compliance with the mechanical properties required by the applicable drawing. Failure of one or more tension test specimens to comply with the requirements shall be cause for rejection of the lot

47、representative of the specimen. See 4.4.5.3.1. 4.4.3.1.4 Adapter. One tension-test specimen shall be taken from each of 2 bars representative of the production lot to determine compliance with yield strength and elongation requirement of the applicable drawing. Failure of either specimen to comply s

48、hall be cause for rejection of the lot. See 4.4.5.3.2. 4.4.3.2 Air pressure test. Each body assembly shall be subjected to a submerged air pressure test to determine compliance with the assembly drawing. Failure of any assembly to comply as evidenced by the presence of air bubbles in the vicinity of

49、 the brazed joint or rising to the surface of the water shall be cause for rejection of the assembly. Body assemblies which comply shall immediately upon removal from the test fixture be stamped with the letter “A“ as indicated on the assembly drawing. See 4.4.5.4. 4.4.3.3 Joint quality. After air pressure testing, but prior to the application of protective coating, body assemblies shall be 18 i Provided
