Information on the most widely used ASTM standards within the materials testing industry
Model: HBS-3000
HBS-3000 Digital Display Brinell Hardness Tester is mainly used for testing the hardness of materials such as cast iron, steel, non-ferrous metals, and soft alloys. The Brinell hardness test is the method with the largest indentation among all hardness tests and can reflect the comprehensive properties of the material. It is not affected by the microstructural segregation or uneven composition of the sample, making it a highly accurate hardness testing method. It is widely used in metallurgy, forging, untreated steel, non-ferrous metals industries, laboratories, colleges, universities, and research institutions.
The software system uses intelligent computer programming and employs photoelectric sensing technology. By selecting testing conditions independently, it can display the testing method, upper and lower limits, measured indentation length, hardness value, converted value, test force, holding time, number of tests, as well as enter the year, month, and date. Test results and data processing can be displayed and output through a built-in printer or connected to a computer via a data interface. The optical system uses high-magnification LED optical measurement, providing high image clarity with adjustable brightness and minimizing fatigue during prolonged operation. The hardware system uses advanced electronic sensor loading technology, with a closed-loop control system where the CPU controls the sensor to collect signals, and a stepper motor automatically applies and releases the test force with automatic compensation to ensure more accurate force values and more stable readings. It is also equipped with an emergency stop device and meets EU CE safety standards, offering user-friendly operation, greater reliability, stability, and safety.

Brinell hardness testing uses high test forces and produces large indentations, making it suitable for hardness testing of metals with large grains, such as cast iron, non-ferrous metals and alloys, steel after various annealing and quenching treatments, and especially for relatively soft metals like pure aluminum, lead, and tin.
Electronic Brinell hardness testers use high test forces and produce large indentations, suitable for testing metals with large grains, such as cast iron, non-ferrous metals, alloys, and steel after various annealing and quenching treatments, particularly for softer metals like pure aluminum, lead, and tin, as well as hardness testing of ferrous and non-ferrous metals.
Brinell hardness testers can be used to test castings, forgings, steel in supplied condition, non-ferrous metals, and semi-finished steel products that have undergone quenching and tempering. This is a portable instrument suitable for workshop use, simple to operate, easy to carry, and capable of on-site testing of large workpieces without sampling, enabling individual inspection of large workpieces.
Brinell hardness testers are mainly used for hardness testing of wrought steel and cast iron with uneven structures. The Brinell hardness of wrought steel and gray cast iron corresponds well with tensile testing results. Brinell hardness testing can also be applied to non-ferrous metals and mild steel; using a small-diameter ball indenter allows measurement of small-sized and thinner materials. Brinell hardness testers are often used for inspection of raw materials and semi-finished products; due to the large indentation, they are generally not used for finished product testing.
The selection of Brinell hardness test conditions is similar to the choice of scale in Rockwell hardness testing. Brinell hardness testing also faces the issue of selecting test conditions, namely the choice of test force F and indenter ball diameter D. This choice is not arbitrary but must follow certain rules, paying attention to the reasonable combination of test force and indenter diameter. Its application is slightly more complex compared to Rockwell hardness testing.
ASTM E10 “Standard Test Method for Brinell Hardness of Metallic Materials”
ISO 6506 “Metallic materials -- Brinell hardness test”
The working principle of the Brinell hardness tester is to press a steel ball of a certain diameter into the surface of the specimen at a certain speed under a specified test force. After maintaining the applied force for a prescribed duration, the force is removed. The Brinell hardness value of the metal is represented by the average pressure on the spherical surface area of the indentation.
