Unless otherwise specified herein, all equip- ment, material, and articles incorporated in the
37、 products covered by this specification shall be new and may be fabricated using materials produced from recovered materials to the maximum extent practicable without jeopardizing the intended use. The term “recovered materialsa means materials which have been collected or recovered from solid waste
38、 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 specifically specified. a Y *f 3.2.2 Prohibited materials. The follow
39、ing materials are prohibited for use in purifiers covered by this specification. (a) Magnesium and its alloys. (b) Cast iron (except nodular iron). (c) Semi-steel. (d) Cadmium plating. (e) Copper alloys in contact with fuel or lubricating oil. (f) Asbestos. 3.2.3 Mercury. The purifier shall be free
40、of mercury contamination. During the manufacturing process, tests and examination, the product to be offered for acceptance shall not come in direct contact with mercury or any of its components, nor with any mercury containing device employing a single boundary of containment. 3.3 Construction. Pur
41、ifiers shall separate contaminants from F-76 and JP-5 fuels, turbine lube oil, and diesel engine lubricating oil. Purified oil or fuel shall be discharged under pressure through closed piping to the ships fuel or lube oil systems, as applicable. Water separated from the oil or fuel shall be continuo
42、usly discharged to ships oily water drain collection system. solids shall collect within the bowl until they are removed by manual cleaning. 3.3.1 General. Purifiers shall have the following characteristics: Separated (a) Manual pushbutton motor start, (b) Manual control for flow of oil after prime.

45、s shall be provided in accordance with MIL-M-17508. 3.3.3 Frames. Purifier frames shall be sufficiently rigid to permit lifting, handling, shipment, and installation of the units on board ship without disturbing the alignment of the assembled units, and so that the normal distor- tion, weaving, or v
46、ibration of the supporting structure on board ships will not cause misalignment of rotating elements. 3.3.3.1 Special handling provisions. Special tools or fittings shall be provided by the manufacturer for lifting all items weighing in excess of 16 kilograms (35 pounds). 3.3.4 Brakes. Purifiers sha
