1. SCOPE

1.1. Scope Statement. The purpose of this Purchase Description (PD) is to define the technical requirements for the 300psig nominal compressed air system.

2. APPLICABLE DOCUMENTS

2.1. Government Documents. The following specifications, standards, and handbooks of the exact revision listed below form a part of this specification to the extent specified herein.

2.1.1. Technical Orders. None.

2.1.2. Department of Defense Standards. None.

2.2. General Industry Regulations. Test stand design shall conform to the following:

2.2.1. NFPA 70: National Electric Code (NEC), latest edition

2.2.2. 29 CFR 1910 Occupational and Health Administration (OSHA) General Industry Regulations

3. REQUIREMENTS

3.1. General. The air system shall connect to the three existing pneumatic component test stands in Room 112 and the existing test stand connection on the south wall of Room 106. The air system design shall consist of new piping from the location of the compressors up to the test stand connection points. The design shall include isolation valves close to each test stand.

3.2. Compressors. The air system shall include a minimum of two (2) compressors, each capable of producing a minimum of 0.5 pounds per minute @ 300 ± 20 psig nominal pressure. The compressors shall be staged with pressure switches so that they run on demand. The compressor controller shall allow the compressors to alternate being the primary supply to keep operating hours more even. Each compressor shall have the ability to be isolated for maintenance while the other(s) remain in operation.

3.3. Air Quality. The air system shall be clean, oil free (<4ppm), and dry (<0°F dew point.) The system shall include a 25 micron or better air filter that can be isolated and depressurized for maintenance.

PD003 5

3.4. Piping. Air supply piping, and valves, shall be non-corrosive material (e.g. stainless steel, anodized aluminum IAW the latest revision of ASME B31.3) rated for all expected temperatures and pressures. Piping shall be sized to match the existing line sizes of the existing pneumatic component test stands.

3.5. Storage. The air system shall include a minimum 50 gallon storage tank. The storage tank shall have an automatic adjustable condensate drain valve.

3.6. Safety. The air system shall conform to the General Industry Requirements listed in paragraph 2.2. The system shall have a safety relief valve.

3.7. Energy Efficiency. To fullest extent possible, the contractor shall incorporate energy efficiencies into the test system design and function (e.g. expected process time, pre-heat, state of equipment during idle time, etc.).

3.8. Hose Requirements. The air system shall not utilize hoses.

3.9. Life Cycle Sustainment. The overall system design (e.g. components, hardware, software, etc.) shall be reliable, accessible, and maintainable and also allow the Government to competitively select service providers for all future repairs without involving the original manufacturer of the system. Wherever possible, the contractor shall use components that are commercially available, commonly used in comparable industry equipment, interchangeable with other brands, and competitively priced. The ATS system design shall not force the Government into a sole-source condition with the original manufacturer of the system when repairs or replacement parts are required. The system design shall not require the Government or a Government contractor to perform any reverse engineering in order to make system repairs.
