manufacturer's standard commercial product. Additional or better features

which are not specifically prohibited by this specification but which are a

part of the manufacturer's standard commercial product, shall be included in

the sprayer being furnished. A standard commercial product is a product which

has been sold or is being currently offered for sale on the commercial market

through advertisements or manufacturer's catalogs, or brochures, and

represents the latest production model.

3.2 First article. When specified (see 6.2), the contractor shall furnish

one complete sprayer and duster unit for first article inspection and approval

(see 4.2.1 and 6.4).

* 3.3 Materials. Materials used shall be, free from defects which would

adversely affect the performance 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, 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. None of the above shall be interpreted to mean that the use of

used or rebuilt products are allowed under this specification unless otherwise

specified.

3.4 Interchangeability. All units of the same classification furnished

with similar options under a specific contract shall be identical to the

extent necessary to insure interchangeability of component parts, assemblies,

accessories, and spare parts.

3.5 Safety. All rotating or reciprocating parts, and all parts subject to

high operational temperatures, that are of such a nature or so located to be

or become a hazard to the safety of the operating personnel shall be

insulated, enclosed, or guarded to the extent necessary to eliminate the

hazard. Each sprayer shall comply with OSHA regulations in effect at time of

manufacture.

3.6 Performance. When operating with an air output velocity as indicated

in table 1, as applicable to the equipment, the combined sound level of the

engine exhaust, blower, and air discharge stream, will not exceed the

recommended level as measured from the operator's station side of the sprayer

and duster unit. When tested as specified in 4.4.1 through 4.4.4.4, the

sprayer and duster unit shall be capable of dispersing insecticide

formulations of oil or water based solutions, emulsions, and suspensions. The

sprayer and duster unit shall also be capable of dispersing insecticide dusts

and granules. The formulations and dusts shall be injected into the air

stream, and homogeneously dispersed at a continuous steady rate. When the

engine is operating at this continuous rated speed, the air nozzle shall

discharge a steady stream of air at not less than one of the volume-velocity
