Brinell hardness testing in laboratory
You would like to carry out a Brinell hardness (HB) testing on your materials
What is Brinell hardness ?
Brinell hardness testing (HB) is a method for assessing the hardness of materials, particularly metals. This method involves the use of a hardened steel ball which is pressed into the material to be tested under a specific load. Brinell hardness is calculated by measuring the diameter of the indentation left by the ball on the material. This method is standardized by various norms, including ASTM E10 and ISO 6506-1.
What are the standards governing Brinell hardness testing ?
ASTM E10
ASTM E10 defines the Brinell hardness measurement method for metallic materials. It details the specifications of the equipment to be used, the test procedure, and how to calculate and report the results.
The standard covers aspects such as
- The size of the steel ball, which can vary according to the material to be tested and the thickness of the sample.
- The test force applied to the sample, which is selected according to the material to be tested and must be maintained for a specified time.
- The method used to measure indentation diameter, which must be accurate to guarantee reliable results.
- The calculations required to determine the Brinell hardness, based on the indentation diameter and the test force used.
ISO 6506-1
ISO 6506-1 also specifies the principles for measuring the Brinell hardness of metallic materials. It covers the following aspects:
- Specifications for test equipment, including the steel ball and loading device.
- Requirements for sample preparation and the test procedure to be followed to ensure consistent, reproducible results.
- The method for calculating Brinell hardness from the indentation left by the ball, taking into account the diameter of the indentation and the load applied.

FAQ
Although the objectives of ASTM E10 and ISO 6506-1 are similar, there may be minor differences in technical specifications, such as ball dimensions, applied load values, or hardness calculation procedures. Laboratories and industries should choose the standard that best suits their specific needs or applicable regulatory requirements.
Following ASTM E10 and ISO 6506-1 standards when measuring Brinell hardness is crucial to ensure consistency and comparability of test results. This enables manufacturers, testing laboratories and industries to ensure that materials meet the required quality and performance criteria. The adoption of these standards also facilitates the communication of material characteristics between the various players in the sector, thus contributing to the safety and efficiency of end products.
