ISO 6506-1 Brinell Hardness Test (Metallic Materials) — Test Method

← Back to all standards

ISO 6506 defines the Brinell hardness test method for metallic materials, covering how Brinell hardness is determined by pressing a ball indenter into the surface and measuring the indentation. To match this to your program, talk with our team.

What ISO 6506 Covers

The Brinell test presses a hard ball into the material under a defined force and measures the diameter of the resulting indentation. The large indent averages over a wide area, which suits coarse or non-uniform microstructures such as castings and forgings.

How the Result Is Obtained

A ball of specified diameter is pressed at a defined force for a set dwell time, and the indentation diameter is measured optically. The Brinell hardness number follows from the force and indentation area.

Why Machine Verification Matters

Reliable Brinell numbers depend on accurate force, a sound indenter, and a calibrated measuring system. Machine verification to a standard such as GB/T 231.2 keeps results traceable.
