Brinell hardness testing (BHN or HBW) involves applying a relatively large load to a hardened steel or tungsten carbide ball indenter, producing a measurable indentation in the test material. The diameter of this indentation is then used to calculate the material’s hardness.
Due to the large contact area, the Brinell method is ideal for:
Castings and forgings
Materials with non-uniform grain structures
Large metal parts where other methods may not give consistent results
Common test loads range from 500 kgf to 3000 kgf, and ball sizes vary depending on the application. Brinell testing is commonly used in foundries, steelworks, and heavy manufacturing.
Our Brinell hardness reference blocks are developed to support machine calibration across a range of Brinell loads and indenter sizes. Each block is marked with its verified hardness value and meets the traceability and tolerance requirements set out by international standards such as ISO 6506 and ASTM E10.
Key features include:
High-grade surface finish for clear indent impressions
Durable construction to withstand repeated use
Precise hardness values across a wide Brinell range
Traceability to UKAS or equivalent accredited laboratories
Our blocks are suitable for both primary and secondary verification processes, supporting laboratory and on-site testing equipment alike.
We supply Brinell reference blocks across a comprehensive range of hardness values to meet the needs of different industries, including:
Low Brinell values (e.g., HBW 75–150) for softer metals such as aluminium alloys
Mid-range Brinell values (e.g., HBW 150–300) for medium carbon steels
High Brinell values (e.g., HBW 300–650) for hardened steel and tool steel
Custom configurations can be arranged to suit your specific machine or industry requirements.
With over 30 years in the industry, Euro Products continues to supply reliable and accurate components for hardness testing systems around the world. Our customers rely on us for:
Consistent calibration standards
Responsive, knowledgeable support

UK-based manufacturing with international reach
Brinell testing demands precision, especially when dealing with materials that present challenges for other hardness methods. Our Brinell reference blocks are built to support your testing process, ensuring every result is one you can trust.
Our Brinell reference blocks are manufactured and calibrated in accordance with international standards including ISO 6506 and ASTM E10. Each block comes with documentation confirming traceability to UKAS or other accredited bodies where applicable.
The lifespan of a Brinell reference block depends on usage frequency and proper handling. With careful use and regular maintenance, they can remain reliable for hundreds of indentations, but we always recommend routine inspections and re-verification to ensure continued accuracy.
Yes. We offer a range of standard Brinell hardness values, but we can also supply custom hardness ranges upon request to suit specific calibration or verification requirements.
