Brinell test

Brinell test

[brə′nel ‚test]
(engineering)
A test to determine the hardness of a material, in which a steel ball 1 centimeter in diameter is pressed into the material with a standard force (usually 3000 kilograms); the spherical surface area of indentation is measured and divided into the load; the results are expressed as Brinell number.

The Brinell test measures resistance to indentation and is a common technique used to determine the hardness of castings.
This adaptability means that Equotip hardness testing remains virtually non-destructive, while a Rockwell or a Brinell test often requires scrapping the object after the test.
There are several types of hardness tests, including the Brinell test, the Rockwell test, the Vickers test and the durometer test.
Although the Brinell test is widely known as one of the most accurate test methods for hardness testing of metals, error in the reading of the indentation size results in measurement errors of 0.
Parts are loaded into the cell, and a carousel moves them to the Brinell test and onto the PCRT test station, which uses a single electronics package to alternately test left and right knuckles.
The standard Brinell test uses a 10mm ball under three different load levels: 500kg, 1500kg and 3000kg.
The most common method of measuring hardness in the foundry is the Brinell test, which is particularly effective on soft materials.
