Vickers Hardness Test
The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a
right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100
kgf. The full load is normally applied for 10 to 15 seconds. The two diagonals of the indentation left in the surface
of the material after removal of the load are measured using a microscope and their average calculated. The area of
the sloping surface of the indentation is calculated. The Vickers hardness is the quotient obtained by dividing the
kgf load by the square mm area of indentation.
F= Load in kgf
d = Arithmetic mean of the two diagonals, d1 and d2 in mm
HV = Vickers hardness
When the mean diagonal of the indentation has been determined the Vickers hardness may be calculated from the
formula, but is more convenient to use conversion tables. The Vickers hardness should be reported like 800 HV/10,
which means a Vickers hardness of 800, was obtained using a 10 kgf force. Several different loading settings give
practically identical hardness numbers on uniform material, which is much better than the arbitrary changing of
scale with the other hardness testing methods. The advantages of the Vickers hardness test are that extremely
accurate readings can be taken, and just one type of indenter is used for all types of metals and surface treatments.
Although thoroughly adaptable and very precise for testing the softest and hardest of materials, under varying loads,
the Vickers machine is a floor standing unit that is more expensive than the Brinell or Rockwell machines.

3.1 Usage of the Instrument
3.1.1 Switch the power source on. The light source and the LCD screen are both lit up at
the same time. At this point, the LCD screen displays as follows:
D1/D2：Diagonal length of indention；HV：Vickers hardness value；T：Dwell time；
N：Numbers of measurements；F：Testing force value；
3.1.2 Once the working screen appears, you can revise the dwell time, testing force value and luminosity of light source,
etc according to operator’s requirement.
3.1.3 Rotate the protecting cover of the indenter to make the 20╳ objective face the front of the instrument. (This
instrument is equipped with a positioning device, you will feel it click into a position socket when you rotate
the protecting cover. The general amplification is 200╳
3.1.4 Place the standard block or the specimen on the testing table and then rotate the hand wheel to raise the table. When
the block or the specimen comes into the distance of 3~4 mm ( 20╳ objective) under the objective, begin
observing the view through the eyepiece. At this point , in the center of the vision field of the eyepiece appears
a bright spot , which is alerting you that you are very close to the focusing plane. At this time raise the testing
table up slowly until the block or specimen surface forms a clear image in the micro eyepiece, which indicates
the focusing operation is completed. (The micro eyepiece, the objective and the working piece are in the
focusing state.)
3.1.5 The luminosity of the light source in the vision field can be regulated through the keys “LIGHT+” or “LIGHT-” on
the operational board.
3.1.6 If there is a need to have a large vision field on the block or on the specimen , just shift the 10╳ objective in the
frontal direction of the instrument . At this time, the general amplification is 100╳ . Both the 10╳ objective and
the 20╳objective can be used for the measurement.

NOTE: 1. When toggling between the objectives 10╳and 20╳ , there might be a
slight change in the vision field. Just adjust slightly the up-and-down lead-screw until the focusing plane is clear.
2. When testing indentation size covers over 60% of the vision field, the hardness value for this
measurement is erroneous
You can have 2 choices:
a) Reduce the testing force;
b) When it is stipulated that the testing force can’t be changed in the
technical file, you must choose the objective with small rate amplification. This is the function
that both objectives can measure.
3.1.7 After the focusing operation is finished, turn the indenter to the front of the
instrument .At this point,the distance between the tip of the indenter and the plane
of the specimen is about 0.4～0.5 mm. When an irregular-shaped specimen is to be
tested, take care not to damage the indenter. The indentor must be perpendicular to
the surface at all times.
3.1.8 According to the requirements of the test, set the dwell time of the test force with
the keys on the operating board. Each push of the button accounts for 5 seconds,
with the key “TIME+” adding time and the key “TIME-” reducing time.
3.1.9 Press the key “START” on the operating board and apply the test force; at this point
(LOADING) LED is lit.
3.1.10 After the test force is applied, DWELL LED lights up. At this time the LCD screen
shows the dwell countdown of the time selected. When the dwell time is up, the test
force UNLOADING LED lights up. After test force UNLOAD LED lights out,
shift the objective selected to front of instrument.
NOTE: When the UNLOAD LED is still on, do not turn the protecting cover of the
indenter; otherwise it would cause damage to the instrument. After pressing
the “START” Key, if you find the objective is in front of instrument instead
of the penetrator, Please be patient to wait until the machine performs the
test cycle. DO NOT ROTATE DURING TEST. Serious damage can occur
3.4.11 Rotate the turntable counter-clockwise to place the 20╳ objective in front of the main body. Turn the drum
wheel on both left and right side of micro eyepiece, so that the operator could see the two graduated lines move
closely as shown in Fig 6. Continue turning eyepiece until the inner sides of graduated lines reach critical state
with no space between them to allow the light to penetrate as shown in Fig 7. Now press the SPEC key and
then press “CLR-D” key to clear the zero, at this point, it has finished to set zero for the eyepiece, the values of
D1 and D2 will show 0.00 on the LCD screen.
