UPI Laboratories Europe BV specializes in the calibration, certification and supply of hardness testing indenters and test blocks for Vickers, Rockwell, Knoop and Brinell. Operating under ISO/IEC 17025 accreditation (RvA), we ensure full traceability and internationally recognized certification through the ILAC network. Our precision-mounted diamond indenters and consistently manufactured hardness test blocks meet ISO and ASTM standards and are available with a NADCAP compliant grid.
Consistent Brinell results start with the right reference blocks. UPI Laboratories Europe BV supplies hardness test blocks and certified indenters so you can verify and monitor your Brinell testers with confidence. Our work on hardness testing indenters is performed under an ISO/IEC 17025 RvA accreditation. This accreditation confirms measurement traceability and periodic monitoring by the Dutch Accreditation Council (RvA) and is internationally recognized through ILAC signatories such as UKAS, DaKKS and COFRAC.
Brinell reference blocks are stable, well-characterized test pieces used to check the performance of a Brinell hardness tester. In Brinell testing, a carbide ball indenter is pressed into the material with a defined force for a defined dwell time, and the diameter of the impression is measured. A certified block gives you a known reference value so you can confirm that your tester, indenter and procedure produce results within the expected range.
UPI blocks make day-to-day checks straightforward. Clear laser engraving supports correct identification, and the controlled surface finish helps you produce clean impressions and repeatable readings. Using reference blocks in routine verification helps you detect drift early, document stability and sustain reliable production decisions.
Choosing a Brinell block depends on the ranges you use, your verification schedule and your reporting needs. Many users select a set that covers low, medium and high hardness to reflect production variation. If you work to specific procedures or customer requirements, our team can advise on a block set that supports your internal checks and audit trails.
UPI Laboratories supports your selection with accredited calibration services for hardness testing indenters and with high-quality tooling that keeps your setup within specification.
While Brinell uses a ball indenter, many laboratories also run Vickers and Knoop microhardness checks. UPI supplies diamond indenters that are precision mounted in exact conformity to the diamond grain structure. All diamond indenters are dual calibrated, meeting the requirements of both ISO and ASTM, helping you maintain consistent hardness programs across methods.
Our carbide balls are produced from the highest and purest quality carbide to ensure accuracy, consistency and reliability. Each carbide ball is evaluated with laser scanning microscopes for Brinell and Rockwell use to confirm compliance with relevant ISO and ASTM standards.
UPI hardness test blocks are manufactured from homogeneous base material, mirror or matt finished, and laser engraved for clear identification. Blocks are available with a NADCAP compliant grid, which helps you plan impressions in a clean pattern and simplifies documentation during audits.
UPI Laboratories performs calibration of hardness testing indenters under ISO/IEC 17025 RvA accreditation. This gives you traceable calibration certificates recognized via ILAC signatories, supporting acceptance by regulators and customers.
Traceability is essential for Brinell testing. UPI’s approach aligns with recognized standards and bodies:
Using certified blocks regularly, alongside certified indenters, helps you verify instrument performance, confirm operator consistency and sustain reliable reporting.
