Brinell tester is setup to test at kg, but other loads of , , , , , and are listed in the standard. The combinations of load and indenter that can be used are as follows: Hardness Scale Ball dia. (mm) Load (kgf) HBW 10/ 10 HBW 10/ 10 HBW 10/ 10 HBW 10/ 10 HBW 10/ Digital Motorized Brinell Hardness Tester. Must be purchased in multiples of 1. A Micro Vickers Hardness Tester with Digicam - Manual Software. A. Must be purchased in multiples of 1. UNPUBLISHED aTitle: Hardness Testers aDescription Brinell Hardness Testers. The Brinell hardness tester is used for testing permanent change of metal specimens using a tungsten carbide ball indenter of various sizes. It measures the resistance of the material to permanent deformation. The diameter of the indentation having deformed the material is then used to calculate the Brinell hardness value.
manual, the tester needed to be forced to make the indicator of the dial point at kg test force for times. Thus it is equivalent to the test condition of Brinell hardness testing method to hold kg test force for seconds with 10mm steel ball, which complies with ASTM E The structure of the instrument is shown as Fig 2) Press ng numer c keys and the ENTER key w ll cause a new low tolerance value to replace. the old one and the d splay to show the current h gh tolerance value (see next example). (Press ng the ENTER key alone w thout chang ng the low tolerance value w ll also cause the. tester to d splay the h gh tolerance value.). Brinell hardness number (BHN) is obtained by the ratio of the calculated load and the spherical area of the Indentation or Impression made on the specimen by the corresponding Indentor Ball.
A Brinell cum- Rockwell hardness testing m/c along with the specimen is shown in figure. Page NATIONAL INSTITUTE OF TECHNOLOGY,SRINAGAR. Department Of CIVIL. Manual reading is easy and straightforward. You look through the lenses, focus the optics, position in the lens on the impression and read the result in mm. The. Windows based software system; Three modes of measurement, manual, semi auto and auto; In auto mode the image is scanned for measurement and hardness is.
