AFMETCAL Det 1 intends to award a purchase order under Simplified Acquisition Procedures for the purchase of an Automatic Microphone Reciprocity Calibration System. This is a combined synopsis/solicitation for commercial items in accordance with the format in the Federal Acquisition Regulation (FAR) Subpart 12.6 and 13.5 as supplemented with additional information included in this notice. This announcement constitutes the only solicitation, proposals are requested and a written solicitation will not be issued. This solicitation F33660-00-Q7509, is a request for a price quotation for an Automatic Microphone Reciprocity Calibration System. This solicitation incorporates provisions and clauses in effect through the Federal Acquisition Circular 97-15 and Defense Acquisition Circular/DCN. FAR clauses 52.212-1, 52.212-3, 52.212-4 and 52.212-5 apply to this acquisition. This document describes the minimum Air Force Primary Standards Laboratory requirements for an Automatic Microphone Reciprocity Calibration System. The System will serve as an absolute standard in the Air Force Primary Standards Sound Laboratory for calibrating Type I and Type II microphones. The equipment/components list outlined within this notice is not intended to be a complete list of what shall be required to satisfy the technical specifications of this requirement. The Government is aware that several additional pieces of hardware and/or software may be required beyond the list provided. A complete, assembled and working system shall be delivered. Prospective suppliers are asked to address each paragraph of this document and provide a summary of how their product will satisfy the requirements. The Microphone Reciprocity Calibrator will employ a method of calibration as outlined in American National Standard Institute (ANSI) S.10 and International Electrical Commission (IEC) recommended practice outlined in 61094/2. The measurement components shall be interfaced with each other and a personal computer so that all measurements can be stored and then used for calculation of final measurement report. Computer screen prompts shall provide the user with required information to accomplish the entire reciprocity calibration. The item described herein is an automatic microphone calibration system typically designed with the following components --  A reciprocity calibration device.  A signal generator.  A digital voltmeter.  Both 1/1 octave and 1/3 octave band pass filters.  A chamber capable of pressure control to accommodate the microphones under test.  A personal "Pentium II " or better computer with IEEE-488 interface, and capable of supporting an ethernet card.  Software capable of communicating with instruments, performing measurements, storing data, calculating required calibration corrections, and printing final measurement reports.  An inkjet quality printer.  In addition to calibration software, one copy each of Microsoft Windows 98operating system and Microsoft Office 2000 shall be supplied with the system. The unit shall be complete and fully assembled with power cord(s), IEEE interface cables, electrical measurement cables, and all accessories necessary for reciprocity calibration of 0.5" and 1.0" microphones. The system shall consist of "off the shelf" commercially available equipment. Frequency Range -- 1.0" Microphones -- 20 to 10,000 Hz0.5" Microphones -- 20 to 25,000 Hz Calibrated Microphone Response Uncertainty Equal to or better than + 0.08 dB System Specifications: Ambient Operating Range: -- 20 % to 45% Relative Humidity 150 to 300 Celsius, Temperature stability + 30 ppm per degree Celsius: Long term drift -Less than 150 ppm per year: Short term drift -Less than 40 ppm per month, Line Voltage -- 120 Volts + 10 Volts Power Consumption -- Less than 30 VA total Weight -Should not exceed 150 kg total Size -Bench Top System not to exceed 1.0 x 2.0 x 1.5 meters (DxWxH) Software: Calibration software shall be user friendly with pull down menus for editing and changing calibration parameters. Measurement data and final report shall be stored in an importable format capable of being sent via local area network to central storage location. A software user guideline shall accompany the software and at minimum contain the following: Software flow process All algorithms used, Variables defined and identified. Constants identified. Software verification plan shall be outlined and results of verification noted. Reliability: The unit shall operate without user required maintenance for extended periods -- the adjustment/calibration interval shall exceed one year. A failure shall be considered as any condition in which the instrument does not meet the performance requirements of this purchase description. Required periodic maintenance will not be considered a failure unless the unit fails to meet the performance specifications of this purchase description. Failures due to physical misuse, cut cables, broken mechanical components, etc will not be considered as failures. Accessories: All accessories necessary for normal operation of the equipment shall be supplied. Warranty: The unit shall be supplied with a standard commercial warranty against faulty workmanship and defective materials. Design And Construction: The unit 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 designed and manufactured to maximize reliability, maintainability, accuracy, and ease of operation. All parts such as switches, controls, etc., shall have proper clearance and adjustments. They shall be capable of withstanding environmental testing of this specification. Calibration: The system shall be capable of being calibrated on site in the Air Force Primary Standards Laboratory with common test, measurement, diagnostic equipment, and/or a Standard Reference Microphone calibrated at a National Standards Laboratory. Technical Manual: The unit shall be provided with two user manuals that contain sufficient material to maintain and operate the equipment as well as a method of calibration for the entire system. A software user guide is required. The successful offeror will be required to provide training at AFMETCAL Det 1 after the unit is delivered. ACCEPTANCE TESTING: The system will be inspected and accepted at destination as specified in the contract. The unit will be inspected and accepted or rejected within 30 days from the date of receipt at AFMETCAL Det 1. The item will be checked with test equipment possessing parameters equal to or better than those required to assure specified performance requirements are met. Test equipment used has first echelon certification directly traceable to the National Institute of Standards and Technology (NIST) where required. Tests will be performed to assure the item meets the requirements. Such testing at destination does not relieve the contractor of performing all inspections and quality checks at the point of fabrication, as is necessary, to assure performance as specified herein. Delivery is required within 120 days after contract award. Delivery shall be FOB destination Heath OH. Please acknowledge all requirements on your quote. Offerors must provide technical detail to clearly demonstrate the offerors understanding and compliance with the minimum requirements listed above. Quotes should be directed to Jim Hood, Contract Specialist, at AFMETCAL Det 1, 813 Irving-Wick Dr W Bldg. 2, Heath, OH 43056-6116. Phone 740-788-5046 FAX 740-788-5157. E-mail jim.hood@afmetcal.af.mil. Offers are due at AFMETCAL no later than 4:00PM E.S.T. on 22 Feb 2000. All responsible sources may submit a proposal, which will be considered.
