Knoop blocks are essential tools for microhardness testing, especially when analyzing thin coatings, small components, or materials with delicate structures. At UPI Laboratories Europe BV, we supply and calibrate high-quality Knoop hardness testing blocks under ISO/IEC 17025 RvA accreditation. Each block is calibrated to meet both ISO and ASTM standards, ensuring global reliability and traceability.
Knoop hardness testing is designed for precision. It uses an elongated diamond-shaped indenter to produce very shallow impressions, making it ideal for analyzing surface treatments, thin films, and layered materials. The corresponding Knoop blocks must reflect the same level of accuracy.
At UPI Laboratories, our Knoop blocks are manufactured with fine-tuned homogeneity and surface quality, ensuring that every indentation delivers valid and repeatable results. The blocks are laser-engraved for clear identification and come with full traceability documentation, meeting the strict requirements of ISO and ASTM standards.
In addition, all our blocks are verified using advanced equipment and are regularly re-evaluated to maintain their calibration integrity over time. This helps ensure consistent performance and long-term reliability, even under frequent use in high-demand testing environments.
Knoop blocks are widely used in laboratories, research centers, and high-tech industries. They are especially useful for:
Whether you’re working in electronics, medical device production, or materials research, Knoop testing provides detailed insight into localized hardness values. Our blocks support reliable machine verification, enabling precise calibration in demanding environments.
The Knoop method is also ideal for studying the microstructure of composites and layered materials, offering valuable insights into individual layers that other hardness tests might overlook.
Due to the shallow and narrow indentation shape, Knoop testing is highly sensitive to surface preparation and indenter quality. That’s why our Knoop blocks are polished to perfection and produced using stable, high-purity materials that minimize variation and distortion.
Each Knoop block from UPI Laboratories is calibrated using advanced optical and digital measurement systems and offers consistent performance across a wide range of low test forces. Every block is verified under ISO/IEC 17025 procedures, providing dependable traceability and confidence in your testing outcomes.
We understand the challenges of microhardness testing and ensure that our blocks meet the exacting standards needed to support your work. Our team also offers advice on optimal test settings and maintenance best practices to help extend the lifespan of your equipment and blocks.
