19、OVISIONS 4.1 Responsibility for inspection. 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 specified in the contract or purchase order, th
20、e contractor may use 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-L-82b53A m 9999906 19723bb 375 m MIL-L-82653A(OS) I .4 his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless dis
21、approved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements (see 6.2). 4.1.1 Responsibility for compliance. All items sha
22、ll 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 responsibility of
23、ensuring that all products or supplies submitted to the Government for acceptance 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 not authorize submission of
24、 known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.2 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed as specified in the applicable test method of 4.4. 4.3 Quality conformance
25、 inspection. Quality conformance inspection shall consist of the tests specified in 4.4.1, 4.4.2, and 4.4.3. When specified in the contract, the contractor shall prepare a report giving the results obtained for all inspections and tests performed and a certified statement that meets all requirements
26、 of this specification (see 6.2). 4.3.1 Inspection lot. An inspection lot shall consist of a single liner mix. 4.3.1.1 Liner mix. A liner mix shall consist of one homogeneous blend of ingredients (see 3.2) manufactured at one time in one mixing vessel. 4.3.1.2 Ingredient lot. The ingredient lot set
27、shall be a set of the materials as specified in table I for each type of liner material, where each of the materials is from a single material lot that is acceptable under the quality provisions of this specification. If one or more of the material lots is changed from an established ingredient lot
28、set this constitutes a new ingredient lot set. If the formulation (the weight percent of the individual ingredients) established with a new ingredient lot set is maintained, no additional testing (see 3.4.1) is required. The testing of 3.4.1 shall be performed if any formulation modification is requ
29、ired with an ingredient lot set, or if the ingredient lot set changes. 4.4 Test methods. Unless an alternative inspection method is proposed, tests shall be performed using apparatus and procedures specified herein. Alternative inspection methods may be proposed by the supplier but must be approved
30、by the contracting activity prior to use in acceptance testing. 4.4.1 Ingredient weight. Each liner ingredient shall be weighed to determine compliance with 3.2 prior to mixing. Weights shall be measured with equipment having an accuracy of & 1 percent of the ingredient weight calculated from the pe
31、rcentages specified in the applicable table (see 3.2). 4.4.2 Raw material. Each liner raw material shall be tested to determine compliance with 3.2. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-L-82653A(OS) a 4.4.3 Bond strength. The liner b
32、ond strength specimens shall be prepared and tested in accordance with CPIA Publication No. 21, section 4.7.2. A minimum of 4 samples shall be tested to determine compliance with 3.4. l. 4.4.3.1 Liner test specimen. The propellant from the propellant mix used to cast the test specimens shall meet th
33、e propellant mechanical properties specified in the applicable propellant specification before the liner bond test is completed. If the propellant does not meet the mechanical properties specified in the applicable propellant specification, all bond testing completed with that propellant mix shall b

Coat the inside of the gripping sleeve with a thin layer of liner. Coat the exposed side of the insulator disc with liner, so that, as a minimum, the in
35、sulator disc is fully covered by liner, c. Cure the liner at 170 & 5F for 14 to 18 hours. d. Assemble the test specimen as shown on figure 4.7.2-1 of CPIA Publication No. 21. e.
