2.2 Part Number Specifications

The terminations of the BNC calibration kit shall be specified to:

DC to 2.0 GHz, Max VSWR ≤ 1.04

2.0 to 4.0 GHz, Max VSWR ≤ 1.10

4.0 to 10.0 GHz, Max VSWR ≤ 1.20

The terminations of the TNC calibration kit shall be specified to:

DC to 4.0 GHz, Max VSWR ≤ 1.06

4.0 to 12.0 GHz, Max VSWR ≤ 1.10

12.0 to 18.0 GHz, Max VSWR ≤ 1.15

3.0 Reliability and Maintainability Requirements.

3.1 Reliability. The design of the calibration kits and adapters shall be such that under normal use and operation the mean‐time‐between‐failure (MTBF) for intermittent operation shall be at least 8000 hours of operation. The time for MTBF begins once the government begins testing as verified by the warranty sticker date. A failure shall be considered any condition in which the calibration kits or adapters do not meet any of the requirements as stated in this PD. Intermittent operation is considered

Attachment 1 to be the summation of actual operation time when RF power is being sourced into or received from any of the calibration kits and adapters.

3.2 Calibration Interval. The OEM shall provide a recommended interval of time for periodic certifications of the calibration kits and adapters which shall be based upon achieving a minimum 85% of units remaining within specified tolerances as set forth in this PD at the end of the recommended interval. The minimum interval between periodic certifications shall be 12 months.

3.3 Maintainability. The calibration kits and adapters shall meet the maintainability requirements listed below.

3.3.1 Preventative Maintenance. The calibration kits and adapters shall not require more than 1 hour preventative maintenance from a skill technicians within a 90‐day period.

3.3.2 Enclosure. The calibration kits and adapters shall have an enclosure. The enclosure shall be constructed of plastic, wood, or fiberglass. The enclosure shall provide protection from mechanical shock and conditions associated with bench‐top use and shall have no openings on the top surface.

3.4 Interchangeability. All units, replaceable assemblies, subassemblies, components, and parts of a designated model provided shall be fully interchangeable without interference or degradation of performance.

4 General Requirements.

4.1 Safety. Protection shall be provided from, but not limited to, safety hazards as specified herein.

4.1.1 Accessible Potentials. Operating and maintenance personnel shall be protected from hazardous potentials by shielding, marking, or other suitable measures. Parts of equipment which become accessible upon removing a cover, opening a door, adjusting a control, setting a supply circuit voltage mechanism, replacing a fuse, attaching and detaching an interconnecting cable assembly, etc. and are intended for access by the operator during normal use shall not render an electric shock.

4.1.2 Grounding. During operation of the fully assembled test equipment, all electrically conductive external surfaces except trim and identification plates shall be at earth ground potential. Ground connection shall be sufficient mechanical strength to minimize the possibility of ground disconnection.

Such ground path shall have sufficiently low impedance and ample capacity to conduct safely any operating or fault currents imposed on it.

4.1.3 Thermal Hazards. Protection shall be provided from equipment temperatures which could constitute a hazard to personnel.

4.1.4 Mechanical Hazards. Suitable protection shall be provided to prevent contact with moving mechanical parts when the equipment is complete and operating. Sharp projections on enclosures shall be avoided.

4.2 Parts, Materials, and Processes. Parts, materials, and processes associated with the equipment shall meet the following requirements.

4.2.1 Coaxial Cable Electrical Insulation. Materials used in electronic cable and connector technology shall be selected such that they degrade by a mechanism other than elimination and shall be resistant to corrosion and reductions in performance.

4.2.2 Commercial Parts. Commercial parts and materials that are used shall have properties consistent with a precision metrology grade laboratory instrument.

4.2.3 Selected Components. Matched and selected components as well as specially built, nonstandard components shall not be used.

4.2.4 Metals. Metals shall be of the corrosion‐resistant type or shall be metallurgically processed or suitably treated to resist corrosion due to atmospheric conditions likely to be met in storage, service, and/or transportation. Dissimilar metals in close contact with each other shall not be present.

4.2.5 Design and Construction. The equipment 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 metrology grade equipment. It shall be designed and manufactured to achieve reliability, maintainability, accuracy of operation, and ease of operation. All parts such as shafts, bearings, regulators, switches, controls, etc., shall have proper clearance and adjustments. They shall work together so that the equipment will supply the rated requirements without unnecessary strains, vibrations, or overheating. They shall be able to withstand the conditions met in shipping, storage, installation, and service. All material and parts of this equipment shall be capable of withstanding the environmental requirements of this specification.

4.4 Equipment Identification. The calibration kits and adapters shall be assigned a model number designation by the manufacturer. Each production unit shall be assigned a unique serial number designation by the manufacturer. The calibration kits and adapters purchase shall follow the Item Identification and Valuation clause as stated in the contract. The information specified below shall be identified on the calibration kits and adapters.

Manufacturer name Equipment name Equipment model number (including options, if any) Equipment serial number

4.5 Warm‐Up, Continuous Operation, Environmental Requirements.

4.5.1 Continuous Operation. After the required warm‐up period, the calibration kits and adapters shall meet all specifications of this purchase description and shall not display any intermittent characteristics or overheating for an extended period of not less than 8 hours of continuous operation.

4.5.2 Operating Temperature Range. The calibration kits and adapters shall meet the specified performance and accuracy requirements within the operating temperature range of 73 ± 5 degrees Fahrenheit.

4.5.3 Operating Relative Humidity Range. The calibration kits and adapters shall meet the specified performance and accuracy requirements within the operating relative humidity range of 20 to 50%.

4.5.4 Non‐operating Storage Temperature. The calibration kits and adapters shall meet specified performance and accuracy requirements after being stored at temperatures ranging from 15 to 140 degrees Fahrenheit (‐9 to 60 Celsius).

4.6 Accessories. All accessories necessary for normal operation of the calibration kits and adapters shall be supplied, not necessarily limited to the following: equipment cases/covers, adapters.

4.7 Metric Products. Products manufactured to metric dimensions will be considered on an equal basis with those manufactured using inch/pound units, provided they fall within the specified tolerances using conversion tables contained in the latest revision of Federal Standard No. 376, and all other requirements of this purchase description are met.

5 Testing Requirements. The calibration kits and adapters shall be inspected and accepted at destination as specified elsewhere in the contract. The item will be checked with test equipment whose parameters are equal to or better than those required to ensure specified performance requirements are met. Test equipment used, where required, has first echelon certification directly traceable to the National Institute of Standards and Technology or other AFMETCAL approved equivalent laboratories.

Tests will be performed to ensure the calibration kits and adapters meets the requirements of this purchase description, OEM commercial manuals, and/or any AFPSL check standards with documented historical data deemed appropriate by the government. Such testing at destination does not relieve the contractor of performing all inspections and quality checks at the point of fabrication, as specified elsewhere in the contract, or as necessary, to ensure performance as specified herein.
