SIST EN ISO 28080:2021 PDF

Overview

EN ISO 28080:2021 - Hardmetals: Abrasion tests for hardmetals is a CEN-endorsed adoption of ISO 28080:2021 that specifies a generic rotating-wheel test method to determine the abrasive wear characteristics of hardmetals. The standard provides a flexible framework for laboratory abrasion testing that can simulate abrasive damage under a range of controlled conditions (dry/wet, different abrasive sizes, varied chemical environments and counterface wheel stiffness such as steel or rubber).

Key Topics

• Scope and purpose: Defines a generic abrasion test suitable for comparative measurements, research and quality control of hardmetals (powder-metallurgy carbides and related composites).
• Test materials: Requirements and guidance for test pieces, abrasives and reference materials.
• Counterface (wheel) options: Use of different wheel materials and sizes (e.g., steel, rubber or neoprene) to represent varied contact stiffness.
• Apparatus and controls:
  • Rotating-wheel test systems and abrasive-feed mechanisms
  • Wheel-speed control and calibration of abrasive flow
  • Vacuum extraction and fluid flow provisions for wet testing
  • Instrumentation for force, friction and mass-loss measurement
• Procedure essentials:
  • Test-piece preparation, cleaning and weighing
  • Clamping, test start/stop and interrupted-test handling
  • Typical operating conditions and number of repeat tests
• Results and reporting:
  • Expression of results for single-step and multiple-step tests
  • Calculation of abrasion rate, graphical trends of wear, friction and normal force
  • Uncertainty of measurement and required elements of the test report

Applications

• Laboratories and test houses conducting comparative abrasion testing for hardmetals.
• R&D teams evaluating new carbide compositions, binders or microstructures for improved abrasion resistance.
• Quality control in powder metallurgy and hardmetal manufacturing to track batch-to-batch consistency.
• Material selection for components expected to face abrasive environments (mining parts, wear components), where controlled simulation of abrasive damage is required.

Note: EN ISO 28080:2021 complements industry-specific wear testing but is not a universal predictor of performance in cutting or milling operations - abrasion tests simulate specific abrasive conditions and should be interpreted accordingly.

Related Standards

• ASTM G65 - Dry sand/rubber wheel test (comparable geometry)
• ASTM G105 - Wet sand/rubber wheel test
• ASTM B611 - Steel wheel high-stress abrasion test

These methods are referenced in the ISO introduction; EN ISO 28080:2021 provides a harmonized framework for reproducibility and comparability across such rotating‑wheel abrasion tests.
