1. SCOPE.

This purchase description (PD) covers the general requirements for a 250 gallon Potable Water Truck.

2. SALIENT CHARACTERISTICS.

2.1 Potable Water Truck description. The Potable Water Tuck shall be capable of servicing military aircraft with potable water, demineralized water, or water/alcohol mixtures. The Potable Water Truck is based on a commercial truck chassis that has been modified for this use.

2.2 Design and construction. The design shall promote cost effective, life-cycle sustainability by addressing considerations such as incorporating open standards, reducing pollutant emissions and wastes, and increasing fuel economy, while satisfying system performance requirements. It shall be designed and constructed so that no parts will work loose in service, and to withstand the strains, jars, vibrations, and other conditions incident to shipping, storage, installation, and service. It shall be weatherproof and designed to prevent the intrusion of water, sand, and dust into critical operating components.

2.2.1 Materials, protective coatings, and finish.

2.2.1.1 Protective coatings. Materials that deteriorate when exposed to sunlight, weather, or operational conditions normally encountered during the service life of the item shall not be used or shall have means of protection against such deterioration that does not prevent compliance with the performance requirements specified herein. Protective coatings that chip, crack, or scale with age or extremes of climatic conditions or when exposed to heat shall not be used. Exposed surfaces of fasteners, handles, and fittings shall also be primed and painted. See 2.2.4.1 for prohibited hazardous materials.
