3 Test principle

After the test methods specified in this part is to use a carbide ball under test force pressed into the surface of the specimen until a predetermined time removing the test Force test, measuring the diameter of the specimen surface indentation, as shown in Figure 1. Conductor Brinell hardness by the formula (1). Brinell hardness = 0.102 × 2F (1) Where. F --- test force in Newtons (N); D --- press ball diameter in millimeters (mm);
