Looking for reliable hardness testing blocks to ensure consistent and accurate material testing? UPI Laboratories Europe BV supplies and calibrates high-quality test blocks for Rockwell, Vickers, Brinell, and Knoop hardness methods. Our blocks are manufactured to meet both ISO and ASTM standards.
Hardness testing blocks are essential for verifying the performance of hardness testing machines. Whether you’re testing metals in aerospace, automotive, or manufacturing environments, using certified and properly calibrated reference blocks is key to achieving valid and repeatable measurements.
At UPI Laboratories, each block is produced using homogenous base materials, finished with a mirror or matte surface, and precision laser-engraved. All blocks are supplied with full calibration documentation, and NADCAP-compliant options are available for regulated sectors. Our goal is to help you maintain confidence in your testing equipment—block after block.
Choosing the right hardness testing block depends on the testing method, material, and specific scale requirements. UPI Laboratories offers a complete range of certified blocks tailored to each method of hardness testing.
Rockwell test blocks are used to verify machines operating under various Rockwell scales such as HRC, HRB, HR15N, and more. Our Rockwell blocks are manufactured to ISO 6508 and ASTM E18 standards and are suitable for a wide range of applications in metalworking and industrial environments.
These blocks are available in multiple hardness levels and include NADCAP-compliant options with grid patterns for traceability. Each block is calibrated using advanced equipment to ensure consistent and accurate values.
Vickers test blocks are ideal for applications requiring high precision and flexibility in load ranges. They are calibrated to ISO 6507 and ASTM E92 standards and offer excellent consistency for both macro and microhardness testing.
Our Vickers blocks are made from carefully selected materials with a high-quality surface finish to support clear and reproducible indentations. Each block is supplied with full traceability and certification.
Brinell blocks are designed for use in testing coarse-grained materials like castings and forgings. These blocks comply with ISO 6506 and ASTM E10 standards and are available in a variety of hardness levels to match different ball sizes and load conditions.
Each block is laser-engraved and manufactured to withstand repeated testing, making them ideal for high-use environments. Brinell blocks from UPI Laboratories ensure reliable results even under demanding conditions.
Knoop testing blocks are used for microhardness testing of thin coatings, small components, and surface layers. They are calibrated to ISO and ASTM standards and verified using high-precision measurement tools.
These blocks provide high accuracy for testing in electronics, materials science, and research labs. Knoop blocks are especially suited for applications where minimal deformation is essential.
At UPI Laboratories, we combine expertise, advanced equipment, and strict quality control to deliver reference blocks that meet the most demanding requirements. Our calibration procedures follow ISO/IEC 17025 standards under supervision of the Dutch Accreditation Council (RvA), ensuring international recognition and acceptance.
Each block is dual-certified to both ISO and ASTM specifications and delivered with complete calibration data. For industries requiring NADCAP compliance, we offer blocks with precision grid patterns for thorough traceability.
Whether you’re managing routine quality control or high-precision research, our test blocks support consistent results, reduce testing errors, and extend the performance of your hardness testing equipment.
