The blackout marker light shall display no evidence of corrosion under visual examination and shall be fully operational, in accordance with 3.4, following the salt atmosphere test of 4.5.2. 3.2.6 Fungus resistance. Materials that are nutrients for fungi sha
21、ll not be used where it is practical to avoid them. Where used and not hermetically sealed, they shall be treated with a fungicide agent in accordance with ASTM G21. However, if they will be used in a hermetically sealed enclosure, fungicidal treatment will not be necessary. 3.2.7 Identification. Eq
22、uipment, assemblies, and parts shall be marked for identification in accordance with MIL-STD-130.

The main two-piece housing shall be constructed from alum
23、inum alloy A360 in accordance with ASTM B85/B85M. 3.3.2 Threads. All screw threads shall be in accordance with FED-STD-H28. 3.3.3 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible,
24、provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life-cycle costs. 3.4 Operation. The blackout marker lights shall give no indication of electrical or mechanical faults when tested in accordance with 4.4.3. 4. VERIFICATI
25、ON 4.1 Classification of inspection. The inspection requirement specified herein is classified as conformance inspection (see 4.3). 4.2 Sampling. 4.2.1 Lot. For purposes of sampling, a lot shall consist of not more than 100 blackout marker lights of the same type, assembled from the same batch of co
26、mponents or subassemblies, and offered for delivery at one time. 4.2.2 Sampling for conformance inspection. A random sample of blackout marker lights shall be selected from each lot and subjected to the inspections specified in 4.3. Sampling shall Provided by IHSNot for ResaleNo reproduction or netw
27、orking permitted without license from IHS-,-,-MIL-DTL-32362 5 be in accordance with ASQ Z1.4, inspection level III, with the acceptance quality limit (AQL) as specified in the contract (see 6.2). 4.3 Conformance inspection. Unless otherwise specified (see 6.2), each of the sample blackout marker lig
28、hts selected in accordance with 4.2.2 shall be subjected to the examinations and tests specified in table I. TABLE I. Conformance inspection.

30、d designs. 4.4.1 Verification alternatives. The manufacturer may propose alternative test methods, techniques, or equipment, including the application of statistical process control, tool control, or cost-effective sampling procedures, to verify performance. Refer to contract (see 6.2) for alternati
31、ves to verifications required by this specification. 4.4.2 Design and materials. Conformance to 3.2 through 3.3.3 shall be determined by inspection of contractor records providing proof or certification that design, construction, processing, and materials conform to requirements. Visual verification
32、 discovering that the required components specified herein are not used shall constitute failure of this test (see 4.4). 4.4.3 Operation. Each sample blackout marker light shall be visually tested by energizing the blackout marker light with 24 VDC to verify proper operation and illumination. Failed
33、 lamps may be replaced. 4.4.4 Visibility. Each sample blackout marker light shall be visually tested by energizing the blackout marker light with 24 VDC to verify the maximum visibility, in feet, on a dark, cloudy night with no moon. The two white apertures shall appear with the unaided eye to be su
34、bstantially equal in brightness. 4.4.5 Apertures. Each sample blackout marker light shall be visually tested by energizing the blackout marker light with 24 VDC to measure in feet at what distance the two apertures appear as one. 4.5 Tests. 4.5.1 Waterproofness. The blackout marker light shall withs
35、tand the waterproofness tests of 4.5.1.1 through 4.5.1.4. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32362 6 4.5.1.1 Saline solution. The salt used shall be sodium chloride containing on a dry basis not greater than 0.1 percent of sodium
36、 iodide and not greater than 0.2 percent of total impurities. The solution shall be prepared by dissolving 5 parts by weight of salt in 95 parts by weight of distilled water or other water containing not greater than 200 parts per million of total solids. The solution shall be kept free of sediment
37、by filtration or decantation. 4.5.1.2 Preparation and initial testing. The blackout marker light, with its electrical connections, shall be submerged in a container with the uppermost surface of the assembly a minimum of 1 inch below the surface of the saline solution. The container and assembly sha
38、ll be installed in a transparent, sealed chamber capable of supporting both vacuum and pressurization. The assembly shall initially be operated while submerged for 30 minutes and shall be carefully observed during its entire period of submersion. 4.5.1.3 Vacuum submersion testing. The chamber shall
39、be evacuated to a pressure 6 pounds per square inch (psi) below atmospheric so as to apply a minimum of 6 psi in internal pressure to all voids within the assembly. During this period, the blackout marker light shall be carefully observed for leakage, as evidenced by bubbles escaping from the interi
40、or of the assembly. Any leakage shall be considered as noncompliance with the waterproof requirement and the assembly shall be rejected. Bubbles that are the result of entrapped air on the exterior surfaces of the component shall not be considered leakage. 4.5.1.4 Pressure submersion testing. The ch
41、amber shall then be pressurized to 6 pounds above atmospheric and the assembly again operated for 30 minutes. The assembly shall then be disassembled as normally required in servicing, and inspection made for the presence of water. If water is present, the assembly shall be rejected. If the assembly
42、 is dry, it shall be reassembled and subjected to 15 hours of dry operation (3 separate 5-hour periods). Insulation breakdown or other damage that would impair mechanical or electrical operation of the assembly shall be considered as evidence of failure and the assembly shall be rejected. 4.5.2 Corr
43、osion resistance. The blackout marker light shall successfully withstand 200 hours of salt atmosphere in accordance with ASTM B117. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is
44、 to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activities within the Military Service or Defense Agency,
45、or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
