  "definition": "An abbreviation for Brinell Hardness, a scale that measures the indentation hardness of materials. The test involves pressing a hard metal ball, the indenter, with a specific force into the surface of the material for a set time, then measuring the diameter of the resulting impression. The Brinell Hardness Number (BHN) is calculated by dividing the test force by the surface area of the indentation; a common test uses a 10 mm steel ball with a 3,000 kgf load.",
