It shall be able to realize those fixed point cells for the calibration of Platinum Resistance Thermometers. It shall also be able to be used as an annealing furnace.

2.2 Units: The Metrology Furnace shall be able to display and operate with at least the following engineering units:

2.2.1 Temperature: °C

2.3 Range: The Metrology Furnace shall have a range of 50 to 500 °C

3.0 FUNCTIONAL REQUIREMENTS:

3.1 Display: The screen shall display all critical control and measurement parameters that are essential to the operation of the Metrology Furnace. The display shall utilize easily-read fonts on a screen with high contrast between characters and background. Each parameter on the screen shall be easily identified and read. The display shall distinguish between ‘set points’ and ‘actual’ measured quantities. It shall be a digital display.

3.2 Front Panel Operation: The Metrology Furnace shall have controls or a touch screen on the front panel of the unit which shall provide access to all functions of the unit.

3.3 Annealing Adapter Compatibility: The Metrology Furnace shall be compatible with existing AFPSL annealing adapter (IsoTech 411-01-11).

3.4 Fixed Point Cell Compatibility: The Metrology Furnace shall be compatible with existing tin (ITL-M-17669) and zinc (ITL-M-17671) full-size freeze point cells .

4.0 MECHANICAL & PHYSICAL REQUIREMENTS:

4.1 Environmental Requirements: The Metrology Furnace shall be able to operate and be stored in the following environmental conditions without loss of required performance:

4.1.1 Temperature: 60 to 90 °F

4.1.2 Humidity: 10 to 90 %RH Non-condensing

4.2 Special Hardware/ Software/Licenses Requirements: Any special equipment, fixtures, tools, standards, etc., required to meet the requirements of this purchase description and not common to a secondary calibration laboratory must be supplied with the Metrology Furnace.

Units that fail calibration and are recommended for alignment or adjustment, either manually or using automated alignment/adjustment software, shall include any special hardware, software, and software licenses needed to perform the alignment/adjustment process.

4.3 Construction: The Metrology Furnace shall be designed and constructed of materials that meet the requirements of this specification and in accordance with the best commercial practices for industry approved equipment. It shall be the contractor’s responsibility to assure the government that such design objectives as reliability, accuracy of operation, maintainability and ease of operation have been given due consideration in the manufacture of this equipment. All parts such as shafts, bearings, regulators, switches, controls, connectors, etc., shall have proper clearance and adjustments. They shall work together so that the equipment shall supply the rated requirements without unnecessary strains, vibrations, and overheating. They shall be able to withstand the conditions met in shipping, storage, installation, and services. All materials and parts of this equipment shall be capable of withstanding environmental testing requirements of this specification.

4.4 Individual Unique Identifier Designation: The Metrology Furnace shall be clearly labeled with a model number, serial number, and manufacturer’s name. Unique item identification labeling shall follow Item Identification and Valuation requirements as stated in the contract.

4.5 AC Power Rating: The power required to operate the Metrology Furnace shall be 208-240

VAC at 50/60 Hz.

4.6 Electrical Protection: The Metrology Furnace shall have a fuse or circuit breaker to protect it in the event of excessive current of AC power. The AC line power fuses shall be user serviceable without removing any covers /panels or voiding a manufacturer’s service warranty.

4.6.1 Electrical Safety: Documentation shall be provided to support the means by which electrical safety considerations have been addressed. The safety of all personnel will be ensured in conductive or nonconductive contact with the outside of the equipment and during the changing of the fuse. Safety shall be ensured with the power to the system and its components are turned on. This documentation shall consist of a minimum of a citation of a UL or ANSI identified standard or equivalent United States Standard to which the equipment conforms.

4.7 Safety Data Sheets: All applicable safety data sheets for all fluids and chemicals shall be provided.

4.8 Additional Hardware: Additional hardware required to make this system function as identified by this purchase description shall be required.

5.0 OPERATOR’S MANUAL: Manual shall include the following:

5.1 Individual Component Listings: The manual shall list the individual components which includes OEM manufacturer’s name, and OEM part number. If applicable, include component range and uncertainty.

5.2 Alignment Procedure: The manual shall have an alignment procedure for the temperature sensors, and any other component that may require periodic adjustment.

5.3 Remote Command Listings: The manual shall list the input/output parameters, command strings and other pertinent data required to accomplish remote operation of the Metrology Furnace.

5.4 Maintenance: The manual shall include preventative maintenance inspection procedures and intervals required for proper operation of the unit.

6.0 WARRANTY & TECHNICAL SUPPORT: A warranty and technical support normally offered by the vendor for this product shall be provided with the unit. The warranty shall last at least one year from delivery.

7.0 ENVIRONMENT, SAFETY, AND OPERATIONAL HEALTH: A combination of the system manual, other documentation, and/or the system itself shall identify potential environment, safety, and operational health hazards and how they are mitigated when the design itself cannot mitigate them.

This will be accomplished through stating the hazard and accompanying mitigation through the use of safety devices, use of warnings, or use of special operational procedures to counter such hazards.

8.0 TESTING: The Metrology Furnace will be inspected and accepted at a destination specified elsewhere in this contract. The item will be checked with test equipment and parameters equal to or better than those required assuring specified performance requirements are met. Test equipment has first echelon certification directly traceable to the International System of Units through the National Institute of Standards and Technology (NIST) or other AFMETCAL approved sources where required. Test will be performed to assure the Metrology Furnace meets or exceeds all of the requirements of this purchase description.
