Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption h

30、as been obtained. 3. REQUIREMENTS 3.1 Specification sheets. The individual item requirements shall be as specified herein and in accordance with the applicable specification sheets. In the event of any conflict between the requirements of this specification and the specification sheets, the latter s

31、hall govern (see 6.2). 3.1.1 Switch categories. Switches furnished under this specification shall be category I or II as defined herein. 3.1.1.1 Category I. Switches completely defined by a military specification sheet. 3.1.1.2 Category II. Switches are the same as category I except for minor differ

32、ences such as terminations, connectors, pressure ports, mounting means, pressure settings, or minor body dimensions which do not change the basic design or construction of the qualified switch. Category II switches shall be acquired from a source listed on the applicable QPL for the particular simil

33、ar product in category I. Category II switches are non standard. Qualification and acceptance testing shall be limited to verification of requirements in excess of the applicable specification sheet. 3.2 Qualification. Switches furnished under this specification shall be products which are qualified

34、 for listing on the QPL at the time set for opening of bids (see 4.5 and 6.3). 3.3 Material. Material shall be as specified herein. When a definite material is not specified, a suitable material shall be used which enables the switches to conform to the performance requirements of this specification

35、. Acceptance or approval of any constituent material shall not be construed as a guaranty of the acceptance of the finished product (see 4.10.1). 3.3.1 Fungus-resistance. All materials shall be nonfungus nutrient in accordance with MIL-STD-810, Requirement 4. 3.3.2 Metals. All metal parts, other tha

36、n current-carrying parts, shall be of corrosion-resistant material, or shall be suitably protected to resist corrosion. Paint is not acceptable for corrosion protection. Brass, copper, cadmium, or zinc shall not be used in contact with fuel. Cadmium or zinc shall not be used in contact with lube oil

37、 or hydraulic oil. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-9395H 8 3.3.2.1 Dissimilar metals. When dissimilar metals are used in intimate contact with each other, protection against electrolysis and corrosion shall be provided. The us

38、e of dissimilar metals which, in contact, tend toward active electrolytic corrosion is not acceptable. However, metal plating or metal spraying of dissimilar base metals to provide similar or suitable abutting surfaces is permitted. The use of dissimilar metals separated by a suitable insulating mat

39、erial is also permitted. Dissimilar metals and compatible couples are defined in 6.5. 3.3.2.2 Magnesium. Magnesium and magnesium alloys shall not be used. 3.3.2.3 Aluminum. Aluminum and aluminum alloys shall be suitably protected against corrosion. When anodized, it shall be in accordance with MIL-A

Solder shall have a minimum melting point of 100F above the maximum temperature rating of the pressure switch and shall conform to J-STD-006. Where solder is

41、employed, flux shall be in accordance with J-STD-004. When stainless steel is used, corrosive flux may be used providing the device is cleaned and the flux is neutralized prior to final assembly. 3.3.2.5 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally a

42、nd externally. Tin content of the switch components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a minimum of 3 percent lead, by mass (see 6.6). 3.3.3 Nonmetals.

44、d for noncase material, thermoplastics shall be in accordance with type I of ASTM-D4066-82. The plastic material used shall be self-extinguishing when tested in accordance with ASTM-D635, as applicable, to the thinnest section of the material used. The self-extinguishing requirement applies to all m

45、aterials for external parts and enclosures regardless of whether the material used is acquired to a military specification. 3.3.3.2 Ceramic. Ceramic insulating material shall meet or exceed the following characteristics: Dielectric loss index: .016 Maximum Average Dielectric strength: 180 to 199 vol
