shall be conducted in the range of 10-250 kgf.
For the measuring of the hardness the Brinell test
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.
