It is very important to measure the hardness of the plastic, without knowing the hardness level of the material you can’t assure its quality if you want to meet the expectations of your customers then the material quality should be very high.
There are several tests used to determine the hardness of materials and to determine the size of the impression left by the test and hardness. One of the renowned tests is named as superficial hardness test or superficial Rockwell hardness test.
The hardness test gives you the chance you determine the properties of the specific material. The physical properties include the three different things such as strength, ductility, and resistance.
Vickers hardness testing is a multifaceted testing method that can be used for both micro and macro hardness testing. Vickers hardness test was developed by George E. Sandland and Robert L. Smith in 1921 as an alternative to the Brinell method for measuring material hardness.
The ability of any certain object or substance to resist indentation when a force is applied to it is known as hardness. An object’s hardness should be classified as a feature or a characteristic rather than one of its properties and the hardness is generally measured by calculating the permanent area of the indentation caused by a fixed load.
But what does hardness actually mean? Despite popular conception, or rather misconception, it certainly does not indicate toughness of a material or substance. Diamond, which is the hardest, would most certainly crack if hit with a hammer. Steel, on the other hand, would not.
There are several hardness tests available in the market according to the type of test, the material of indenter, the type of sample, etc. Since the past few decades, there has been a surge in the market for the hardness testers.
What is the Brinell hardness method? Brinell hardness method is an optical method that works by measuring the intensity of indentation that is caused by an indenting material. Brinell hardness method applies an indenter that is spherical in shape, unlike the Vickers hardness method that applies the use of pyramid-shaped indenter that is pressed on […]
