Unless otherwise specified in the con- tract or purchase order, the contractor is responsible for the performance of all inspection requirements as specified herein. in the contract or purch
37、ase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements speci- fied herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspec
38、tions are deemed necessary to assure supplies and services conform to prescribed requi remen t s . Except as otherwise specified 4.1.1 Responsibility for compliance. All items must meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the co
39、ntractors 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 products or supplies submitted to the Government for acceptance comply with all require- ments of the co
40、ntract. Sampling in quality conformance does not authorize sub- mission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Objective evidence. The contractor shall provide objective evidence acceptable to the contract
41、ing officer that the requirements of 3.1, 3.2 and section 5, for which specific inspection has not been provided in this specifi- cation have been satisfied. 4.2 Classification of inspection. The inspection requirements are classi- fied as follows: (a) Preproduction inspection (see 4.3). (b) Quality
42、 conformance inspection (see 4.4). 4.3 Preproduction inspection. 4.3.1 Preproduction lot. A preproduction lot of components suitable to assemble and pack a minimum of 750 M11 SPAL shall be produced using the same methods, materials, equipment, and processes as will be used during regular production.
43、 4.3.2 Inspection procedure. 4.3.2.1 For examination and nondestructive tests. A random sample of 15 each components, subassemblies, assemblies and packaging along with 15 packed M11 SPAL shall be examined 100 percent to all drawings dimensions/requirernents and this specification. The sample for mo
44、isture content of black powder shall be conducted in accordance with MIL-P-223.

The raw material of burster housings shall be tested in
45、accordance with table I. The 100 housing caps shall be tested in accordance with 4.4.4.2. Twenty-four burster housings from each cavity, mini- mum of 96 burster housings, shall be tested in accordance with 3.1.2.3(2)(a). The burst height for 50 assembled (10 sets of five) Ml1 SPAL shall be tested in
46、 accordance with 4.4.4.1. 4.3.3 Acceptancelrejection criteria. The preproduction samples shall meet all the requirements for examinations and tests listed in the drawings and this specification to be acceptable. The acceptance number is zero. The process control values submitted shall be acceptable
47、only if the burster housing pro- duced thereby meet the requirements as verified by the actual test data desig- nated in this specification. The procedure for process control certification shall likewise be acceptable to the Government. The contractor shall obtain written approval from the contracti
48、ng officer prior to proceeding with regular production. 4.4 Quality conformance inspection. 4.4.1 Lotting. A lot shall consist of like components or subassemblies (including explosive material) of one interfix from one manufacturer, from the same materials, and under essentially the same manufacturi
49、ng conditions. Each lot shall be identified and controlled in accordance with MIL-STD-1168. Data cards shall be prepared for each lot in accordance with MIL-STD-1167. 4.4.2 Sampling. 4.4.2.1 For examination and nondestructive tests. Sampling shall be con- ducted in accordance with MIL-STD-105. Sampling for the 5-gallon steel drum shall be conducted in accordance with MIL-STD-105 using an AQL of 0.65 percent defective. 4.4.2.2 For destructive
