3.2.1 Recycled, recovered materials. Unless otherwise specified herein, all equipment, material, and

articles incorporated in the work covered by this specification are to be new and fabricated using

materials produced from recovered materials to the maximum extent possible 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. Unless otherwise specified, none of the above shall be interpreted to mean that the use of

used or rebuilt products is allowed under this specification.

3.2.2 Wire reinforcement. Reinforcement wire shall be stainless steel, brass- or zinc-plated high

tensile carbon steel wire, as specified (see 1.2.4 and 6.2).

3.2.3 Coupling components. All coupling components, except washers and contact surface inserts,

shall be cold-rolled steel bar stock or malleable iron in accordance with ASTM A47/A47M, grade 32510,

or ductile iron in accordance with ASTM A536, grade 60-40-18 or grade 65-45-12, and shall be protected

with a corrosion-resisting coating. Gray iron castings in accordance with ASTM A48/A48M shall not be

acceptable.

3.3 Length. The hose shall be furnished in nominal 25 or 50-foot (7620 or 15240 mm) lengths,

exclusive of the couplings, as specified (see 6.2). A tolerance of 1 percent shall be permitted when

tested as specified in 4.7.1.1.

3.4 Construction. The hose assembly shall be constructed as specified in tables I, II, III, IV, and V,

and 3.4.1 through 3.4.3.
