- Description
- The Naval Air Warfare Center Aircraft Division Lakehurst, N.J. (NAWCADLKE) intends to issue a Request for Proposals (RFP) to procure a series of temperature calibration baths from Hart Scientific, Inc. 799 E. Utah Valley Drive, American Fork, UT 84003-9775 to update/replace the current inventory of older model temperature baths. This procurement will be for commercial off the shelf items (COTS). A sources sought request was previously advertised in September, 2002 along with technical specifications. Only one company responded (Hart Scientific, Inc). A total of 57 baths with accessories (19 baths each of three model numbers) will be purchased. An initial basic quantity of 6 baths is planned with follow-on options available up to the full quantity. Hart model numbers include: 7040 low temperature unit, 6020 medium temperature unit and the 6050H high temperature unit. Accessories include fluid level adapters (all units), economy clamp kits (all units), fast start heater (high temp unit) and bath fluid (all units). Specifications: The temperature bath or baths must be commercially available, "off the shelf" items with existing product specifications, manuals, technical information and test results that can be made available for comprehensive review and/or evaluation as required. As previously stated, this is NOT a developmental item and, as such, the Navy's goal is to avoid the prolonged waits, developmental costs and re-engineering associated with developmental type procurements. A minimum initial quantity (approx 6) is planned followed by government-discretion options for additional quantities. Due to the NAVAIR Metrology and Calibration Program accuracy requirements for these temperature baths, limited sources of supply were expected. Temperature bath standards are used primarily in NAVAIR depot-level calibration facilities, including the regional labs, Mobil Calibration Complexes (MCCs) and several FCAs (field calibration activities) having special capability. These standards are used to support a wide range of workload items that cannot physically fit into the Portable Temperature Calibrators (PTCs) and/or require a higher degree of calibration accuracy than the PTCs can provide. Furthermore, their larger access opening size enables calibration of the multiple Test Instruments (TIs) simultaneously. The following provides a listing of several types of TIs that are calibrated with the temperature baths: Liquid In Glass Thermometers, Bi-Metallic Thermometers, Remote Indicating Thermometers, Temperature Switches, Thermistors, Digital Multimeters, Pyrometers. Digital Indicators, Thermocouple Thermometers, and Digital Thermometers Unless otherwise indicated, the specifications below are written around a single bath; although, it may be necessary to employ a system of baths in order to satisfy all of the requirements (see MULTIPLE BATH UNITS). The requirements for the temperature baths are as follows: The temperature bath shall operate on 115 VAC and less than 20 amps. The temperature bath shall have a drainage system to permit drainage of the bath fluid. The bath, or system of baths, shall cover a temperature range of -40 ?F to 1000 ?F. The bath and corresponding bath fluid shall be chosen such that they can be safely operated over the required temperature range (provided in TEMPERATURE RANGE) and the permissible exposure limits set forth in the 29 Code Of Federal Regulations 1910 (Occupational Safety and Health Standards) for any substances generated or intrinsic to the specific bath fluids without requiring the use of a fume hood. Navy testing has indicated that certain bath fluids used over specific temperature ranges will not exceed the Short-Term Exposure Limit (STEL) and Permissible Exposure Limit (PEL) set forth in the 29 Code Of Federal Regulations 1910: Dow Corning Corporation- Dow Corning 200? Fluid, 5 CST: -40 to 80 ?C Dow Corning Corporation- Dow Corning 200? Fluid, 50 CST: 60 to 180 ?C Heatbath Corporation- Tempering A-HTS PINK/PETRO AG: 180 to 550?C Although the temperature bath mediums are not limited to those indicated above, any and all conditions outside those previously stated must demonstrate the capability of satisfying the exposure limits set forth in the 29 Code Of Federal Regulations 1910 without the use of a fume hood or other similar ventilation device. Documented proof by an accredited Occupational Safety and Health Standards Agency must be provided. The stability for the bath and fluid shall be 0.011 ?F (0.006 ?C) or better at any temperature set point within the temperature range requirements for approximately a 30-minute duration (sufficient time for TI to stabilize and to make a measurement). This stability shall be achievable while using the same fluid (see TEMPERATURE BATH MEDIUM, section 1). If multiple bath units are necessary to cover the temperature range, then each bath shall provide the aforementioned stability over the range the bath and fluid will be used. A stirring mechanism within the bath is preferred in order to expedite and maintain stability and uniformity throughout the bath fluid or medium. The temperature bath shall be able to provide a minimum immersion depth of 12 inches. The access opening shall be at least 4" in diameter (circular), 4" x 4" (rectangular or square) or equivalent. Larger access opening is preferred to facilitate the calibration of multiple workload items simultaneously. The working volume shall be comprised of, at a minimum, a depth of 12 inches and a diameter of 4 inches. This volume shall be unobstructed. The temperature bath medium shall be chosen such that the following hold: 1) One bath fluid or medium for the temperature range over which the bath will be used. If more than one bath is used to cover the temperature range requirement (-40 to 1000 ?F), then a bath fluid shall be selected such that it is not necessary to change / exchange the fluid in order to cover the range over which the bath will be used. 2) The use of the bath fluid or medium over the operating temperature range of the bath shall not require the use of a fume hood as a result of hazardous substances (i.e., fumes/vapors) generated by the fluids and/or to remove displaced particles (i.e., aluminum oxide, sand, etc.) in the air due to use. 3) To reiterate from the TEMPERATURE STABILITY requirement, the bath fluid or medium shall satisfy the stability requirement over the temperature range requirement. If more than one bath is used to satisfy the temperature range requirement, then the fluid in each bath shall be stable over the entire temperature range that the bath is used. A label with the maximum safe operating temperature in accordance with the temperature bath medium requirements (section TEMPERATURE BATH MEDIUM) is preferred. If the temperature bath is capable of operating at temperatures that exceed the safe operating temperature range of the bath fluid, there shall be some mechanism to prevent the operator from operating the bath beyond the safe operating temperature of the bath fluid. Additionally, there shall be some mechanism to disable the unit or shut the unit down in the event of thermal runaway. The temperature display shall provide a visual indication of the current bath temperature. The temperature bath display shall provide a set-point resolution of 0.001 ?C / ?F or better. The temperature controller shall accept a desired temperature set point and the bath able to achieve that set point within an acceptable time period. See heating and cooling below. The temperature display shall provide temperature indications in the following measurement units: Celsius (?C) and Fahrenheit (?F). The bath shall permit the calibration of a test instrument at a minimum of 4 equally spaced test points (including -40 ?F and 1000 ?F as the minimum and maximum test point values, respectively) within a 6-hour period. This time period includes the time necessary for the bath and the corresponding fluid to heat and/or cool while in transit to the test points and also to stabilize with the test instrument and/or standard monitoring device for measurements made at all four test points. There shall be a mechanism/fixture that permits the bath fluid or medium to be brought to a suitable working depth for particular workload such as the liquid in glass thermometers and short-stem dial thermometers. This fluid-leveling capability may result from the actual construction of the bath or an appropriate adjustable leveling fixture that permits the TI to be brought to the level of the bath fluid. Although a single bath capable of satisfying all of the requirements is desired, there are limitations imposed by the bath fluids themselves. Hence, it may be necessary to employ a system of baths in order to satisfy the requirements. If more than one bath is necessary to satisfy the requirements (i.e., cover the temperature range), the following shall be considered during the evaluation (i.e., all else being equal, a three-bath system occupying only x amount of space will be selected over another system occupying 2x amount of space): 1. Combined total volume of the system, including additional equipment necessary for operation (i.e., compressor). 2. Total square footage of lab space occupied by the baths. The temperature bath shall have at least one standard IEEE-488 parallel interface for data transmission and reception for automated calibration and bath monitoring. Interested persons may identify their interest and capability to respond to the requirement or submit proposals. A determination by the Government not to open the requirement to competition based upon the responses received to this notice, is solely within the discretion of the Government. Information received as a result of this notice will normally be considered solely for the purpose of determining whether to condut a competitive procurement. The Government will not pay for information received. All responses should be directed to Mrs. Joyce Discenza. The estimated Issue Date for this solicitation is 12 December 2003.
