34、ited herein, the text of this document takes precedence. Nothing in this document however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3, REQUIREMENTS 3.1 General. Air conditioners covered by this specification shall consist of a condensing unit section
35、and an air handlinglevaporator section and a motor controller. An air discharge plenum shall be included, if specified (see 1.2 and 6.2A). These air conditioners shall be self-contained and shall perform as specified herein when connected to cooling water, drainage, and electric power in accordance
36、with UL 465 and AR1 210. The refrigerant systems shall be constructed in accordance with the requirements of ASHRAE 15. Welding shall be in accordance with MIL-STD- 278 except radiography is not required. Qualification of brazers shall be in accordance with NAVSEA o900-LP-oO1-7ooO. Qualification of
37、welders shall be in accordance with Mil-STD-278. 3.2 First article. When specified (see 6.2), a sample shall be subjected to first article inspection (see 6.5) in accordance with 4.3. 33 Reliability. The minimum acceptable mean-time-between-failure (MTBF) for each air conditioner shall be 10,000 ope
38、rating hours. 3.3.1 Air conditioner failure. Failure of an air conditioner shall be defined as any event which requires unit down for corrective maintenance that requires more than 2 hours to perform. Any corrective maintenance that may be completed by a ships force in less than 2 hours, and is supp
39、orted by on board repair parts and tools, shall not be considered to be a failure. 3.4 Materials, Materials shall be as specified herein for the systems and components the appropriate application of which is accepted by NAVSEA in conjunction with first article tests. The use of alternate materials s
40、hall not be permitted unless such alternate materials have been successfully tested during the air conditioner first article tests or have been accepted as alternate 7 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-A-Lqb5C 41 m 9999906 0474286 7
41、 m MIL-A- 19865C( SH) materials by NAVSEA. The materials shall be free from any defects that might affect the serviceability or appearance of the finished product. The material identification shall include the commercial, industrial, Federal or Military specification to which the material conforms,
42、and shall indicate the type, grade, or class of the material if such classification is delineated in the applicable material specification. 3,4,1 Mercury restriction. Mercury and mercury-containing instruments, except fluorescent or necessary vapor lighting, shall not be used in the manufacture or t
43、esting of any item used in these air conditioners (see 6.3 and 6.10). 3.4.2 Other dangerous materials. Materials which may produce dangerous gases or cause other harmful effects under conditions, including fire, encountered in Naval shipboard service shall not be used (see 6.10). Magnesium and its a
44、lloys shali not be used in the manufacture of the air conditioners or in any component parts. 3.4.3 Corrosion protection. Corrosion-resisting steel, copper, brass, bronze, chromium, copper- nickel, and copper-nickel alloys as specified herein are considered corrosion-resisting materials. Where corro
45、sion-resisting steel is used, it shall be type 304, 316, or 347 in accordance with ASTM A 276. Corrosion-resisting steel, when fabricated by any method that tends to reduce corrosion- resisting properties, shall be normalized to restore those properties before being used in the assembly of any unit
46、(see 4.5). 3.4.3.1 Non-corrosion-resisting materials. Parts other than corrosion-resisting materials shall be protected against corrosion by the use of chemicals, electrolytic processes, plating, or paints and enamels. 3.43,2 Fastenings or fittings, Bolts, nuts, studs, pins, screws, and such other f
47、astenings or fittings shall be of corrosion-resisting material. Self-tapping screws with machine screw threads may be used in the cabinet assembly. Sheet metal screws with sheet metal threads shall not be permitted. 3.4.4 Galvanic corrosion. Unless otherwise specified (see 6.2), direct contact of el
48、ectrolytically dissimilar materials shall be avoided to prevent galvanic corrosion, 3.4.5 Recovered materials. Unless otherwise specified herein, all equipment, material, and articles incorporated in the products covered by this specification shall be new and may be fabricated using materials produc
49、ed from recovered materials to the maximum extent practicable without jeopardizing the intended use. The term “recovered materials“ means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials. None of the above shall be interpreted to mean that the use of used or rebuilt products is allowed under this specification unless otherwise speci
