Description

This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). QUANTITY OF ONE: HIGH TEMPERATURE CAPACITIVE EXTENSOMETER (INSTRON MODEL 2632-050 OR EQUAL)FOR MEASURING STRAIN IN CERAMIC MATRIX COMPOSITES AT TEMPERATURES IN EXCESS OF 2000 C. SIC EXTENSION RODS AND KNIFE EDGES. General chacteristics: Must fit following design objectives: 1. This capacitive extensometer must require no special shoulders, flags, or indentions on the specimen. 2. The extensometer applies an extrememly light contact force (35 grams) to the specimen. 3. The extensometer employs a single knob " engage" and "release" allowing the user to easily establish gage length. 4. The extensometer can load hot or cold specimens. 5. The extensometer is vacuum compatible (106 TORR) 6. The calibrator is mounted on the extensometer mounting post for ease of calibration without moving the extensometer. 7. A vee bearing linear slide mounting with five inches of travel enables the user to remove the rods from the furnace to facilitate speciment change, and re-insert the rods in a repeatable position. 8. The extensometer is capable of measuring microstrain at temperatures up to 1600 C on materials suchas alumina, silicon carbide and other advanced ceramics. Parts: 1). High Temperature Axial Capacitive Extensometer. Item is to meet or exceed salient characteristics of Instron Extensometer (Catalog Part Number #2632-050). Components parts must be interchangeable with pre-existing Instron capacitive extensometers (cat.part #2632-050) already in. Extensometer must be supplied pre-calibrated as follows: +/- 0.10 mm = +/- 10.0 VDC. Operating force at each knife edge must be user adjustable from less than 0.5 grams up to 200 grams. Gage length must be 25 mm. Gage length accuracy to meet +/- 0.05 mm. Gage length repeatability must meet +/-0.02mm. Operating temperature range from ambient to 1600 C (specimen) without cooling. Maximum frequency to be 3 Hz TYP (amplitude dependent). Calibration characteristics Displacement range +/-0.10 mm strain range +/-0.004 mm/mm Max. Displacement Error 0.001 mm Max. Strain Error 0.00004mm/mm Resolution 0.0001 mm Repeatability 0.0003 mm Hysteresis 0.0002 mm Output Sensitivity 100V/mm Sensitivity to knife edge displacements of 0.5mm caused by specimen rigid body motion to be less than 0.5 microns. Capacitive Sensor Conditioner Electronic characteristics Power Requirement 105 to 130 VAC, 50-60 Hz Analog Output +/- 10 VDC (Cat # 2632-050) This capacitive extensomenter will measure low strains at high temperatures. Will incorporate two lever arms which pivot about their centers on a horizontal axis to transmit strain deformation to a transducer located outside the furnace. Each lever arm uses SiC in front, within the furnace, to contact the specimen. The back rods, composed of fused quartz, extend away from the furnace and hold the components of the capacitive sensor, allowing it to operate at ambient conditions. The two lever arms will be supported on jewel bearings by a frame assembly which is pivoted on a third horizontal axis midway between the two lever arm axes. 2). Knife Edge. Item to fit the form, fit and function of Instron part #3118-233. Chisel contact knife edges composed of Carborundum Hexaloy SA. Interchangeable with existing SiC rods. 3). Mounting Fixture. Item to fit the form, fit and function of Instron Catalog part Number 3118-237. A mounting system that allows the extensometer to be mounted to Instron 4502 electromechanical load frames which are equipped with mounting holes. Includes a 2.0 inch diameter vertical post to which the extensomenter and calibrator can be attached. 4) Precision calibrator. Part is to meet or exceed salient characteristics of Instron Precision calibrator (CAT#2118-232). Must allow extensometer to be calibrated while in place on the load frame. Must have a 2.0 in diameter clamp to fit the 3118-237 extensometer mounting assembly. The provisions and clauses in the RFQ are those in effect through FAC 97-20. The NAICS Code and the small business size standard for this procurement are 334519 and 500, respectively. The quoter shall state in their quotation their size status for this procurement. All qualified responsible business sources may submit a quotation which shall be considered by the agency. The DPAS rating for this procurement is DO-C9. Quotations for the items(s) described above are due by close of business 1-31-01 and may be mailed or faxed to Sheree A. Fratus-Purchasing Agent MS 500-306, 21000 Brookpark Road, Cleveland, Ohio 44135. Fax # (216) 433-2480, and include, solicitation number, FOB destination to this Center, proposed delivery schedule, discount/payment terms, warranty duration (if applicable), taxpayer identification number (TIN), identification of any special commercial terms, and be signed by an authorized company representative. If the end product(s) quoted is other than domestic end product(s) as defined in the clause entitled "Buy American Act -- Supplies," the quoter shall so state and shall list the country of origin. The Representations and Certifications required by FAR 52.2l2-3 may be obtained via the internet at URL: http://www.grc.nasa.gov/WWW/Procure/rforms.html The FAR may be obtained via the Internet at URL: http://www.arnet.gov/far/ The NFS may be obtained via the Internet at URL: http://www.hq.nasa.gov/office/procurement/regs/nfstoc.htm Award will be based upon overall best value to the Government, with consideration given to the factors of proposed technical merits, price and past performance; other critical requirements (i.e., delivery) if so stated in the RFQ will also be considered. Unless otherwise stated in the solicitation, for selection purposes, technical, price and past performance are essentially equal in importance. It is critical that offerors provide adequate detail to allow evaluation of their offer (see FAR 52.212-1(b).
