Materials used in the manufacture of transmitters shall be suitable for the purpose and shall conform to applicable government specifications. Materials conforming to Provided by IHSNot for ResaleNo reproduction or networking permitt

21、ed without license from IHS-,-,-MIL-DTL-38394E 4 contractors specifications may be used provided such specifications are approved by the government and contain provisions for adequate tests. The use of the contractors specifications will not constitute waiver of government inspection. 3.2.1 Fungus-p

22、roof materials. Materials that are nutrients for fungi shall not be used where it is practical to avoid them. 3.2.2 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible, provided that

23、the material meets or exceeds the operational and maintenance requirements and promotes economically advantageous life cycle costs. 3.2.3 Metals. Metals shall be of the corrosion resistant type or suitably treated to resist corrosion due to fuels, salt fog, or atmospheric conditions likely to be met

24、 in storage or normal service. 3.2.4 Dissimilar metals. Unless suitably protected against electrolytic corrosion, dissimilar metals as defined in MIL-STD-889 shall not be used in intimate contact with each other. 3.2.5 Nonmagnetic materials. Nonmagnetic materials shall be used for all parts of the t

25、ransmitter except where magnetic materials are essential. 3.2.6 Corrosive fumes. Materials used in the construction of the transmitter shall not produce corrosive or deleterious fumes under the test conditions specified herein. 3.2.7 Protective treatment. When materials are used in the construction

26、of the indicator that are subject to deterioration when exposed to climatic and environmental conditions likely to occur during 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 specification

27、. Protective coatings that will crack, chip, or scale with age or the extremes of climatic and environmental conditions shall not be used. 3.3 Design and construction. 3.3.1 Design. The transmitter shall be designed to operate with indicators conforming to MIL-DTL-6856 and MIL-I-7057. 3.3.1.1 Outlin
