66 -- MICROHARDNESS TESTER SOL 1-067-DME.1845B POC Jane Druen, (804) 864-2442. 1 each - Microhardness Tester System; specifications: shall have a load range from 0.1 gramforce (gf) or less to 50 gf or greater and include at least 8 different loads. The Contractor shall demonstrate at NASA Langley Research Center a procedure for verification of the correspondence of nominal load versus actual load; load application method shall ensure minimal impact loading on a test sample; shall have the capabilities of varying loading dwell time from 5 seconds or less to 50 seconds or greater and of varying loading rate from 30 microns (micro meters) per second or less to 50 microns per second or greater; the selection of load and load application/release shall be automatic, so as to reduce vibration input and to maintain high sensitivity with negligible impact loading; shall have an optical system capable of both Bright Field and Dark Field imaging so that the small indentations produced by the lightest load are accurately readable to 0.01 micron or better; shall include an electronic measuring microscope with a 10X eyepiece and a turret with 10X and 100X objective lenses where all lenses are suitable for Bright Field and Dark Field imaging; shall include a digital display where microhardness measurements are given with a measuring accuracy of 0.01 micron or better; shall include a vibration resistant specimen stage with micrometers for the X and Y traverses; shall be equipped with a specimen claming device for self-leveling metallographically mounted specimens, a universal clamping vise with at least a 50 mm opening capability and a rotary table with graduations at a suitable interval (such as 5 degrees); shall include both Knoop and Vickers indenters which shall operate acceptably at all loads; shall include both a Knoop and a Vickers test block, each one calibrated for use in the ultra-light load range; shall include an accessory case containing at least spare lamps, fuses and some basic tools; shall operate on 115 Vac, 60 Hz, single phase; the Contractor shall provide two sets of operating instructions and maintenance manuals; shall include installation assembly, initial setup, and calibration of the tester on both Knoop and Vickers scales in NASA Langley Research Center's laboratory; shall include certification (to show that the tester meets or exceeds requirements) of the tester in NASA Langley Research Center's laboratory and issuance of a test certificate. The following acceptance test shall be performed: Knoop hardness tests at loads of 0.1 gf, 1 gf, 5 gf, and 25 gf shall be performed on a titanium sample (to be provided by NASA Langley Research Center). The Knoop hardness numbers shall show a decreasing trend with increasing load; shall include training at NASA Langley Research Center in the proper use of the tester for five people for one day.
