Applicable Standards
- ASTM E92 — Vickers and Knoop hardness
- ASTM E384 — applicable microindentation procedures
- ISO 6507-1:2023 — Vickers test method
- ISO 6507-2 — machine verification
- ISO 6507-3 — reference-block calibration
- ASTM E140 and ISO 18265 — hardness conversions
ISO 6507-1:2023 applies to Vickers impressions with diagonal lengths between 0.020 and 1.400 mm. ASTM E92 covers Vickers forces across a broader 1 gf–120 kgf range, while forces at or below 1 kgf may also require consideration of ASTM E384. ASTM E92 information
Important Limitation
The minimum force is 1 kgf. Very thin coatings, microscopic phases or shallow case-depth traverses may require a lower-force micro-Vickers tester.
Applications
- Heat-treatment verification
- Hardened and tempered steels
- Tool steels and alloy steels
- Stainless steel and non-ferrous metals
- Carburized, nitrided and induction-hardened layers
- Case-depth profiles on prepared cross-sections
- Welds and heat-affected zones
- Fasteners, gears, shafts and bearings
- Cutting tools and dies
- Small precision components
- Suitable metallic coatings and deposited layers
- Metallurgical laboratories
- Production quality control
- Research and failure-analysis support

Frequently Asked Questions
What is the maximum test force of the QE-DVH50?
The maximum test force is 50 kgf, corresponding to an HV50 Vickers test.
What is the minimum test force?
The standard configuration begins at 1 kgf, corresponding to HV1.
Is this a microhardness tester?
The QE-DVH50 can perform selected low-force Vickers tests beginning at HV1. Applications requiring forces below 1 kgf—such as very thin coatings, microscopic phases or shallow hardness gradients—require a dedicated microhardness tester.
Does the machine apply the test force automatically?
Yes. Loading, dwell and unloading are performed automatically after the test cycle is started.
Is indentation measurement fully automatic?
No. The standard configuration uses a digital measuring eyepiece. The operator aligns the measuring lines with the two indentation diagonals, and the instrument calculates the Vickers hardness result.
