3. REQUIREMENTS
3.1 Specification sheets. The individual item requirements shall be as specified herein and in
accordance with the applicable specification sheet. In the event of any conflict between the
requirements of this specification and the specification sheet, the latter shall govern.
3.2 Qualification. Relays furnished under this specification shall be products which are authorized by
the qualifying activity for listing on the applicable Qualified Products List (QPL) at the time of award of
contract (see 4.3, 4.4 and 6.3). The Qualified Products List (QPL) associated with this inactive for new
design specification will be maintained until acquisition of the product is no longer required whereupon
the specification and QPL will be canceled.
3.3 Materials. Materials shall be as specified herein. However, when a definite material is not
specified, a material shall be used which will enable the relays to meet the performance requirements of
this specification. Materials used externally shall be fungus inert, self-extinguishing, and shall not
support combustion, nor give off noxious gases in harmful 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 any of the tests specified herein. Cotton-filled or wood-flour-filled materials
shall not be used. Ceramic used for external surfaces shall be glazed. The use of silicone (see 6.8) or
silicone compounds for any purpose is prohibited. The selection of materials shall be such as to provide
maximum shelf life. Acceptance or approval of any constituent material shall not be construed as a
guaranty of the acceptance of the finished product.
3.3.1 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 magnesium or
magnesium alloys is prohibited (not applicable to contacts).
