DIN EN ISO 6507 is the DIN/EN adoption of the ISO 6507 series for Vickers hardness testing on metallic materials. It is widely used to generate HV hardness values for production QA, incoming inspection, heat treatment verification, and metallurgical investigations.
Because ISO 6507 is published as a multi-part series, most purchasing specs and customer drawings cite a specific part (for example the test method part versus the machine verification parts). If you need help matching your requirement to the correct edition and test range, talk with our team.
DIN EN ISO 6507 — Metallic materials — Vickers hardness test
DIN EN ISO 6507 is the commonly referenced European/German designation for the Vickers hardness test framework used across many metal products and process controls.
In practice, this designation typically points to a set of coordinated documents covering the test method, tester verification/calibration, reference blocks, and supporting hardness tables.
Quick definition
Vickers hardness testing uses a diamond pyramid indenter to create an impression in a metallic surface. The hardness value (HV) is determined from the applied force and the measured size of the indentation.
Typical output: Vickers hardness value reported as HV with additional details such as the applied test force/dwell and the referenced edition or procedure requirements.
What this standard covers
DIN EN ISO 6507 covers the core expectations that make Vickers hardness results comparable between labs and production sites.
Common coverage areas include: how the indentation is made and measured, how results are expressed and reported, and how Vickers hardness testing machines are confirmed using reference artifacts and defined verification routines (depending on the cited part).
Why this standard matters in testing
Hardness is often used as a fast, practical proxy for confirming material condition and processing results (for example heat treatment uniformity, surface treatment effectiveness, or batch-to-batch consistency).
DIN EN ISO 6507 matters because Vickers results are sensitive to setup details such as surface preparation, indentation measurement quality, and tester verification status. Aligning your workflow to the cited ISO 6507 part helps reduce disputes when hardness values are used for acceptance decisions.
Common materials, product types, or applications covered
Vickers hardness testing is commonly selected when you need a single indentation method that can be applied across a wide range of metals and hardness levels, including workpieces where small indentation size is important.
Common applications: heat-treated steels, tool steels, nonferrous alloys, weld and HAZ investigations, case depth or surface-hardening checks (with appropriate loads and spacing), and hardness mapping across sections or microstructural features (when low-force configurations are used).
Common test or verification workflow
DIN EN ISO 6507 can drive both the day-to-day hardness testing workflow and the metrology controls around the tester.
A typical workflow includes:
- Prepare a stable, suitably finished test surface so the indentation can be formed and measured reliably.
- Select an appropriate Vickers test force and dwell for the material and the objective (bulk hardness vs. small-feature or near-surface checks).
- Make the indentation(s) with a Vickers indenter and measure the indentation diagonals (manually via optics or automatically via image analysis, depending on system configuration).
- Report hardness values as required by the controlling document or customer specification, including any required test conditions and location details.
- Maintain confidence in the measurement by following the relevant ISO 6507 verification/calibration expectations for the machine and by using certified reference blocks when required.
Equipment commonly used for this standard
DIN EN ISO 6507 most directly points to Vickers hardness testing systems and the supporting metrology needed to keep the results defensible.
Common equipment: Vickers hardness tester (macro/micro/low-force configurations depending on the application), diamond pyramid indenter, optical measurement system or camera-based automatic evaluation, stable anvil/fixtures for the part geometry, and certified Vickers reference blocks for verification routines.
Practical selection note: The right tester configuration is usually driven by the required force range, indentation measurement approach (manual vs. automatic), throughput needs, and how strictly your quality system must follow formal verification routines.
How to read this designation or revision
DIN EN ISO 6507 is typically used as the family name for the Vickers hardness test documents adopted by DIN and EN from ISO.
Many requirements are tied to a specific part number and edition date (for example “DIN EN ISO 6507-1” for the test method). When quoting equipment or writing procedures, it is best to capture the complete citation shown on the customer requirement, including the part number and the edition/date suffix if present.
Related standards, methods, or frameworks
Hardness testing programs often combine multiple indentation methods and/or hardness conversions depending on product form, thickness, and customer reporting needs.
Common related references: ISO hardness conversion guidance (when conversions are permitted by the controlling specification), and other ISO metallic hardness test families such as Brinell (ISO 6506 series) and Rockwell (ISO 6508 series) when alternative scales are specified.
