Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise sp
26、ecified 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 disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the s
27、pecification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 ResDons ibilitv for comDliance. All items shall meet all requirements of Sections 3 and 5. The inspections set forth in this specification shall become a part of the con
28、tractors overall inspection system or quality program. The absence of any inspection requirements in this specification shall not relieve the contractor of the responsibility of ensuring that all products and supplies submitted to the Government for acceptance 4 Provided by IHSNot for ResaleNo repro
29、duction or networking permitted without license from IHS-,-,-MIL-P-71158 997790b 1970739 T92 MIL-P-71158 (AR) comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does
30、 not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. *. 4.1.2 General movisiou . Unless otherwise specified herein, the provisions of MIL-A-48078 apply and form a part of this specification. References shal
31、l be made to MIL-STD-109 to define quality assurance terms used herein. 9. 4.2 -sification of inssection . The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.3). b. Quality conformance inspection (see 4.4). 4.3 First article inssect ion. 4.3.1
32、,Sub missio n. The contractor shall submit a first article sample as designated by the Contracting Officer for evaluation in accordance with the provisions of 4.3.2. The first article sample shall be 500 gm of XM46 propellant for chemical testing. A sample of propellant for ballistic testing will be
33、 submitted in accordance with the provisions of the contract. The sample shall be obtained from the first production lot which has been produced by the Contractor using the same production processes, procedures and equipment as will be used in fulfilling the contract. All materials shall be obtained
34、 from the same sources of supply as will be used in regular production. In addition, a new sample, or portion thereof, as directed by the contracting officer, shall also be submitted whenever a change occurs in the manufacturing process, material used, specification or source of supply as to signifi
35、cantly affect the product as determined by the contracting officer. The contractor is in no way authorized by the Government to initiate production of a second lot of propellant until the first article test has been completed and the results are found to be acceptable. 4.3.2 Insnect ions to be nerfo
36、r med. The sample will be subjected by the Government to any or all of the examinations or tests specified in Table II (MIL-A-48078). 4.3.3 Reject ion. If any test specimen fails to comply with any of the applicable requirements, the first article sample shall be rejected. The Government reserves th
37、e right to terminate inspection upon any failure of a test specimen to comply with any of the requirements.

Unless otherwise approved by the Contracting officer, a lot of XM46 liquid propellant shall be no less than 5,000 Kg. In addition the following
40、 criteria shall apply: A lot shall consist of one or more batches of propellant produced by one manufacturer, in accordance with the same specification, or same specification revision, under one continuous set of operating conditions. Each lot shall consist of that quantity of XM46 propellant that h
41、as been blended and was subjected to the same unit chemical or physical process intended to make the final product homogeneous. The criteria and procedures for the assignment of lot numbers shall be in accordance with MIL-STD-1168. Also, MIL-A-48078 shall apply. Furthermore, a lot of propellant shal
42、l contain: a. Hydroxyl ammonium nitrate from not more than one manufacturer using the same manufacturing process. b. Triethanol ammonium nitrate from not more than one manufacturer using the same process. 4.4.1.1 Blendinu of batc hes. When batches of propellant are blended to form a lot, all batches
43、 that are to make up the lot must simultaneously be placed in one vessel and mixed until homogeneous or the contractor must receive prior approval on a blending procedure if the condition above is not met (See 6.5). 4.4.2 Examination. See MIL-A-48078. a. Classification of characte ristics. Quality c
44、onformance examinations and tests are specified in the following Classification of Characteristics paragraphs. The contractors quality program or detailed inspection system shall provide assurance of compliance of all characteristics with the applicable drawings and specification requirements utiliz
