The INNOVATEST Hardness Converter app is your all-in-one tool for fast and accurate hardness value conversions and calculations. With this app you can easily convert results across ASTM, ISO, and GB standards, with support from all major scales including Vickers, Brinell, Rockwell, and Knoop.
The built-in Hardness Calculator allows you to compute hardness values, diagonals, and tolerances without relying on manual tables. The app automatically detects out-of-range values and mismatches diagonals, ensuring precision every time. The app also enables you to conveniently save and revisit your conversions for quick reference. If you’re considering buying INNOVATEST products, you can use the app to explore and experience our full range of hardness testers, portables, and consumables in Augmented Reality using your mobile device.
To download the app and discover more about its features, visit the dedicated INNOVATEST App Support page.
Hardness testers can be calibrated using special tools and software. Calibration can only be performed by trained personnel.

Calibrating a hardness tester ensures accurate, reliable, and repeatable test results. Over time, mechanical wear, environmental conditions, or usage can affect the tester’s performance. Regular calibration verifies that the instrument meets international standards like ISO and ASTM, which helps maintain product quality, comply with industry regulations, and pass audits.
Whether you use Rockwell, Brinell, Vickers, or Knoop methods, proper hardness tester calibration minimises measurement errors and ensures traceability to certified reference blocks.
ISO 6508 specifies calibration and verification procedures for Rockwell hardness testing machines and applies to all Rockwell and superficial Rockwell scales. The standard requires both direct and indirect verification.
Direct verification checks the accuracy of forces, indenter geometry, and depth-measuring systems using traceable instruments. Indirect verification uses certified Rockwell reference blocks to confirm accuracy in practical testing conditions.
Calibration should be performed by an accredited laboratory or qualified technician using traceable equipment at specified intervals or after maintenance, relocation, or suspected performance issues. ISO 6508 ensures consistency across Rockwell hardness measurements and is essential for testing laboratories operating under ISO 17025 or similar quality systems.
As of 2025, ASTM maintains several updated standards for hardness tester calibration:
These standards define procedures for verifying force accuracy, indenter shape, measurement systems, and testing performance through certified reference blocks. Each method requires both direct and indirect verification, performed at routine intervals or when the tester is serviced or moved. Compliance with ASTM calibration standards is vital for ensuring measurement integrity and audit readiness across manufacturing, research, and quality control environments.
