Brinell testing can be used for all types of metals, and it offers a very accurate and simple testing method. However, manual reading via microscope has a high risk of human error and requires training and concentration to achieve accurate results. Because the formula for the Brinell Hardness Number (BHN) calculation depends on the indent impression reading, these readings require high accuracy.
The B.O.S.S system virtually eliminates operator influence on the test result and represents the most significant technological improvement since the introduction of Brinell testing. It measures Brinell impressions faster, more accurately, and more consistently than other solutions, and it improves quality control with advanced data acquisition and analysis capabilities.
The B.O.S.S. System uses a compact scanning head attached to a computer using the B.O.S.S software to measure impression diameters in seconds and yields a measurement resolution of 0.01mm. The B.O.S.S software is used to set up the criteria for the reading and performs the necessary Brinell Hardness Number calculations to ASTM standards. The system also accounts for such anomalies as impression roundness and surface finish of samples.
