This purchase description outlines the requirements for a 250-gallon Potable Water Truck (NSN 2320 00 089 8979) for military aircraft servicing. Key features include an open-standard design for life-cycle sustainability, weatherproof construction, and specific material, coating, and finish requirements (e.g., semi-gloss green or tan exterior). The truck must prevent water intrusion, have proper drainage, and use elastomers compatible with various water and antifreeze mixtures. Markings, identification plates, and instruction plates must adhere to MIL-STD-130. Environmental, Safety, and Occupational Health (ESOH) standards prohibit Class I/II Ozone Depleting Substances, hexavalent chromium, and cadmium, and require a dry chemical fire extinguisher and noise levels not exceeding 85 dBA. The truck must meet EMI standards (MIL-STD-461), human systems integration (MIL-STD-1472), and specific fastening and welding requirements. The cargo tank must be 300 series stainless steel with a 250-gallon capacity, manhole, sight gauge, and drain valve. The pumping system must deliver 20 GPM at 40 PSI, include an FDA-approved hose, electric rewind reel, and camlock connections, all housed in an illuminated compartment. The cab requires overhead lighting and air conditioning. The truck must operate from -40°F to 125°F and be stored from -65°F to 160°F, enduring rain, snow, ice, solar radiation, fungus, salt fog, sand, and dust. Dimensions are limited to 288x96x85 inches. Transportability via surface modes (highway, rail, water) must comply with MIL-STD-1366 and MIL-STD-209 for tie-downs. Maintainability is designed per MIL-STD-1472, minimizing special tools and including diagnostic software. Performance criteria include a 60 mph maximum speed, cross-country mobility, 20-degree gradeability, 11.5-degree side slope negotiation, and a 60-foot turning diameter. It features an automatic transmission, appropriately rated axles and suspension, power-assisted steering, and hydraulic or full-air brakes with ABS. A compliant diesel engine (EPA Tier III optional) is required, with starting aids for cold temperatures, a robust cooling system, and compatibility with various fuels (JP-5, JP-8, F-24, Jet A/A1). The electrical system is 12-volt DC, with an alternator, maintenance-free batteries, and a winterization system for the engine, cargo tank, and pumping compartment, powered by an external 110/120 Volt AC source. Hydraulic systems, if used, must meet SAE ARP1247 and use MIL-PRF-83282 fluid. Technical data, including operator, service, repair, and illustrated parts breakdown manuals, must be provided digitally with specific data rights. Service bulletins are required for new maintenance issues. Workmanship standards ensure freedom from defects. Regulatory compliance emphasizes recycled, recovered, environmentally preferable, or biobased materials per FAR 23.403 and the Green Procurement Program. Conformance is verified through first production and continuous inspections, including environmental, weight, dimension, transportability, performance, and mobility tests, with many certifications accepted in lieu of testing.
