15、nufacturers standard commercial product, shail be included in the spray outfit being fiimished. A standard commercial product is a product which has been sold or is being currently offered for sale in the commercial market through advertisements or manufacturers catalogs, or brochures, and represent
16、s the latest production model. 3.1.1 System of measurement. The dimensions used in this specification are not intended to preclude the use of the metric system of measurement in the fabrication and production of the material, individual parts, and finished product, provided form, fit, and fiinction
17、requirements are satisfied. 3.2 First article. When specified (see 6.2), the contractor shail furnish a spray outfit of the type, as required for first article inspection and approval (see 4.2.1 and 6.3). 3.3 Materiais. Materials used shall be fi-ee from defects which would adversely affect the perf
18、ormance or maintainability of individual components or of the overall assembly. Materials not specified herein shall be of the same quality used for the intended purpose in commercial practice. Unless otherwise specified herein, all equipment, materiai, and articles incorporated in the work covered
19、by this specification are to be new and fabricated using materials produced from recovered materials to the maximum extent possible without jeopardiPng the intended use. The term “recovered materials“ means materials which have been collected or recovered fiom solid waste and reprocessed to become a
20、 source of raw materials, as opposed to virgin raw materials. Unless otherwise specified, none of the above shall be interpreted to mean that the use of used or rebuilt products are ailowed under this specification. 3.4 Desim The design of the paint spray outfit shall be in accordance with current e
21、ngineering practice. Parts of the paint spray outfit shall be the suppliers current design. AU parts shall be of such size, material, and strength as to sustain the maximum loads imposed with an adequate factor of safety, work efficiency, and with minimum wear during operation. The outfits and acces
22、sories supplied shall be designed for minimum maintenance with a minimum of special tools for maintenance operations. The design shall permit ready access for repair and service. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-00-s-2927 W 9999974 0

All spray outs of the same classification fiirnished with similar options under a specific contract shall be identical to the extent necessary to ensure interchangeability of component parts, assemblies, accessories, and spare parts. 3.5 Construct
24、ion. Construction shall be fiee of any characteristics or defects that will prevent the paint spray outfits from passing any of the examinations and tests specified in section 4. The paint spray outfits shall be complete so that when connected to the specified source of power, can be used for any op
25、eration for which they were designed. 3.5.1 Threads. All threaded fasteners shall be in the inch system and shall comply with ASME B1.l. 3.5.2 Hose connections, gun.

31、uns shall be air pressure spray type and shall be designed to spray vertical, horizontal, overhead, and intermediate surfaces with paint, varnish, enamel, shellac, and other fast drying or setting materials having viscosities of 15 and 30 seconds, using a No. 4 Ford cup at 77 degrees Fahrenheit (OF)
32、 (25 degrees Celsius (OC). The guns shall be as light in weight as practical, consistent with reliability. The design shall be such that paint compounds will not come in contact with the air control parts. The gun shall be easy to clean, simple to adjust, and so designed and constructed as to produc
33、e complete atomization and uniform spray of paint compounds. The weight of the gun shall be not greater than 2 pounds (0.9 kilograms (kg). 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-00-S-2927 = 74 0375035 04T 004-2927 3.6.2.1 Body.
