Materials used externally shall be fungus inert (see 6.12), self-extinguishing, and shall not support combustion, nor give off noxious gases in h
34、armful quantities. Materials used internally shall not give off gases in quantities sufficient to cause explosion of sealed enclosures, cause contamination of the contacts or other parts of the relay that will adversely affect life or reliability, or form current-carrying tracks when subjected to an
35、y of the tests specified herein. The use of silicone or silicone compounds internally for any purpose is prohibited. The use of silicone elastomers internally for relays fully rated 25 amperes and above is acceptable. The selection of materials shall be such as to provide maximum shelf life. Accepta
36、nce or approval of any constituent material shall not be construed as a guaranty of the acceptance of the finished product. 3.4.1 Metals. Metals shall be of a corrosion-resistant type or shall be plated or treated to resist corrosion. The use of mercury or mercury compounds is prohibited. The use of
37、 magnesium or magnesium alloys is prohibited (not applicable to contact systems). 3.4.1.1 Plated finishes. a. Pure tin plating is prohibited internally and externally.

When dissimilar metals are used in intimate contact with each other, protection against electrolysis and corrosion shall b
39、e provided. The use of dissimilar metals in contact, which tends toward active electrolytic corrosion (particularly brass, copper, or steel used in contact with aluminum or aluminum alloy), is not acceptable. However, metal spraying or metal plating of dissimilar base metals to provide similar or su
40、itable abutting surfaces is permitted. Dissimilar metals should be as defined in 6.6. In hermetic seals, the 0.25 volt difference between the header material and the housing material is not applicable. 3.4.2 Magnet wire. Magnet wire shall be of such quality as to ensure that the relay meets all the
41、performance requirements of this specification. 3.4.3 Plastic. Plastic shall be of such quality as to ensure that the relay meets all the performance requirements of this specification 3.4.4 Ceramic. Ceramic shall be of such quality as to ensure that the relay meets all the performance requirements
42、of this specification. 3.5 Interface and construction. Relays shall meet the interface and construction requirements specified in 3.1 (such as weight or physical dimensions). 3.5.1 Attitude. Relays shall be constructed so as to ensure their proper operation when mounted in any position. 3.5.2 Mounti
