EN 24506 is a European standard test method for compression testing of hardmetals (cemented carbides), focused on determining ultimate compressive strength and proof stress under uniaxial compressive loading.

EN 24506 — Hardmetals: Compression test
EN 24506 describes a uniaxial compression test approach for hardmetals to support material qualification, process control, and comparative performance checks where compressive properties are required.
This document is commonly used when hardmetal components are expected to carry high compressive loads in service, and when a numeric compressive strength or proof stress value is required for acceptance or benchmarking.
Quick definition
Document type: Test method (compression test for hardmetals).
Primary outputs: Ultimate compressive strength and proof stress under uniaxial compression (as defined by the standard).
Core setup concept: A test piece is loaded axially in compression between hardmetal bearing blocks until the specified deformation is reached or failure occurs.
What This Standard Covers
EN 24506 focuses on determining compressive properties of hardmetals using a controlled, axial compression loading arrangement.
It addresses the overall test arrangement and the expected test deliverables (including a defined way to express results and document the test in a report).
Why This Standard Matters in Testing
Hardmetals are often selected for stiffness and wear resistance, but compressive performance can also be critical—especially for parts that see high contact stresses or compressive loading in tooling and wear applications.
Because hardmetals are sensitive to alignment, bearing conditions, and machine stiffness during compression, standards-based testing helps reduce disputes about whether a result reflects the material or the test setup.
Common Materials, Product Types, or Applications Covered
EN 24506 is typically associated with hardmetals (cemented carbides) used in demanding, compression-dominated or contact-stress applications.
Common examples: Wear parts, tooling components, and hardmetal grades evaluated during material development, incoming inspection, or production quality control.
Common Test or Verification Workflow
Compression testing to EN 24506 is usually run as a controlled lab procedure that emphasizes repeatable load introduction and axial alignment.
Common workflow steps: Prepare and identify the test piece, configure compression loading using appropriate bearing blocks, apply axial compressive load to the required endpoint (deformation or failure), and report proof stress and ultimate strength in the format expected by the standard.
Equipment Commonly Used for This Standard
EN 24506 testing typically points to a compression-capable universal testing machine (or dedicated compression system) configured for high stiffness and excellent alignment control.
Common equipment: Universal testing machine or compression tester with appropriate force capacity; compression platens/fixtures suited for axial loading; hardmetal bearing blocks; load measurement (calibrated load cell); and a displacement/strain measurement approach appropriate for the proof-stress determination.
For quoting and configuration, the practical details that usually drive selection are force range, frame stiffness, alignment features, bearing block approach, and how deformation/proof stress will be captured and reported.
How to Read This Designation or Revision
Designation: “EN 24506” refers to the European standard number; it is often cited with a publication year (for example, with a “:YYYY” suffix) and may appear with a national prefix when adopted by a specific country.
Revision sensitivity: Test setup details and reporting expectations can depend on the exact edition referenced in a customer or regulatory requirement, so match the cited edition before finalizing fixtures, measurement approach, and report templates.
Practical note: Many catalogs show EN 24506 as withdrawn and replaced by an EN ISO adoption of ISO 4506; confirm which designation your requirement calls out before running compliance tests.
Related Standards, Methods, or Frameworks
EN 24506 is aligned with ISO 4506 (Hardmetals — Compression test) and is commonly encountered alongside later EN ISO adoptions of the ISO document.
If a contract references ISO 4506 or EN ISO 4506 instead of EN 24506, treat that as a cue to confirm edition, acceptance criteria, and reporting language before testing.
