Vickers Hardness Test is a flexible hardness test technique that is used to measure both macro and microhardness. It is appropriate for a variety of applications and materials and has a wide load range.

A lot of people believe that the Vickers hardness test is simpler to use than other hardness tests for the following reasons:

• The procedure can be carried out using a universal or micro hardness tester;
• The calculations necessary are independent of the indenter size;
• The same indenter (a pyramidal diamond) can be used for all materials, regardless of hardness.

Your indentation will deform the surrounding material and change its properties when you do a Vickers hardness test, regardless of the microhardness tester you employ. The Vickers hardness testing standards specify a specific distance between multiple indentations in order to prevent errors in interpreting perceived hardness.

These are the standard dimensions of NextGen’s Vickers Hardness Test Blocks:

Diameter: 1.25″

Heavy Load Vickers – from 1kg. – 50kg.
2.0″ Square – 50 x 50mm

1/4” Thickness – 6.35 mm
Range: 80 UHN – 800
For 800 & up 1.25″ diameter (32mm)
