In the event of a conflict between the text of this specification and the references cited herein, the text of this specification chal 1 take precedence. 3. REQUIREMENTS 3.1 First article. When specified, a sample of the carbon di
15、oxide inflation equipment or component shall be subjected to first article inspection (see 4.3 and 6.3). 3.2 Materials and components. Materials and components shall conform to applicable specifications and drawings as listed or required herein. Materials and components which are not covered by appl
16、icable specifications or drawings, or are not specifically described herein, shall be of the best quality, of the lightest practicable weight, and entirely suitable for the purpose intended. Unless otherwise specified, the materials and components, except for the metallic parts (excluding the carbon
17、 dioxide cylinder), used in the construction of the inflation equipment shall have been manufactured not more than 12 months prior to the date of delivery of the inflation equipment. No magnesium alloys shall be used. 3.2,l Metals. The metals used in the inflation equipment shalT be of the corrosion
18、 resistant type or shall be suitably protected as specified herein to resist corrosion due to salt spray or atmospheric conditions to which the inflation equipment may be subjected, when in storage or during normal service 1 ife. 3.2.1.1 Dissimilar metals. Dissimilar metals, as defined in MIL-STD-88
19、9, shall not be used in intimate contact with each other, unless suitably protected against electrolytic corrosion by means of protective coatings. 3 Licensed by Information Handling ServicesflIL-I-I3b7C 42 W 779770b 0232348 T MIL-I-18369C 3,2,2 Protective treatment. When materials are used in the c
20、onstruction of the Inflation equipment that are subject to deterloration, when exposed to environmental conditions likely to occur durng service usage, they shall be protected against such deterioration in a manner that will in no way prevent compliance with the performance requirements of this spec
21、ification. Protective coatings which might crack, chip, or scale during normal service life or under extremes of environmental conditions shall not be used. 3.3 Design and construction. The design and construction of the inflation equfpment shall conform to Drawings 63A120H1 and 55C3689, as applicab
22、le. 3.3.1 Cylinder valve. The cylinder valve shall be designed to operate freely under all conditions to which it may be subjected and shall be operable from any direction of pull. The valve shall provide an unrestrictive passage of the carbon dioxide gas to the manifold without leakage. The valve s
23、hall operate and discharge the carbon dioxide gas through the manifold and into the raft, when the remote type of actuation is held and the raft is allowed to drop freely. Except for the actuation, the valve shall not have any parts easily removable by hand. The valve outlet shall be of the non-reco
24、iling type and shall be designed to eliminate any recoil of the cylinder if discharged when being disconnected.

31、1.2 Patch. A patch, fabricated from natural rubber, shall be securely molded to the body of the inlet manifold. The bonding material shall not affect the rubber patch or metal and shall not exude, become brittle, or stiff. The side of the patch, to be cemented to the outer sideof the raft inflatable
32、 tube, shall be flat. The composition shall be such that it shall have good cementability properties and shall be capable of being cemented, without difficulty, to the life raft tube cloth conforming to MIL-C-23070, Variety C, with the adhesive conforming to MMM-A-139, Class 1 or 2. Except for the d
33、ischarge holes, all the parts of the manifold, which will be located adjacent to the raft inflatable tube, shall be completely covered with a heavy layer of the same material as the patch to prevent chafing of the raft tube cloth. 3.3.2.1.3 Replacement. Replacment of any expendable ,parts shall be p
34、ossible from the ends of the manifold body. manifold body shall be constructed of the aluminum alloy conforming to QQ-A-225/5, Temper T4, and shall be anodized in accordance with MIL-A-8625.
