Hardness comparison plates – Precision measurement plates for material hardness testing
Hardness comparison plates are indispensable tools for precise material hardness testing and are used for the indirect calibration and verification of hardness testing equipment. In our range, you will find hardness comparison plates that meet the highest quality standards and are ideal for use in industrial and laboratory-based testing. To ensure the reliability of your testing equipment’s results, regular checks using hardness comparison plates should be performed on your material hardness testing device. This process is an essential part of a thorough quality management system and compliance with applicable standards.

What are the benefits of hardness comparison plates from a DAkkS-accredited laboratory?
Purchasing hardness comparison plates from a DAkkS-accredited laboratory guarantees you the highest accuracy and quality. DAkkS accreditation confirms that the laboratory meets the stringent requirements for measuring technology and traceability. You can rely on the fact that the plates have been tested according to applicable standards and that the calibration is traceable to national and international standards. This assurance is especially important for companies operating in regulated industries that must comply with ISO 9001 or other quality management standards.
- Stringent requirements for measuring technology and traceability
- Tested according to applicable standards
- For regulated industries according to ISO 9001
How often should hardness testing equipment be calibrated?
Calibration intervals depend on the frequency of use, the level of strain, and industry-specific standards. A common recommendation is annual calibration by an accredited laboratory (e.g., DAkkS-accredited). However, for intensive use or in particularly demanding environments, shorter intervals may be appropriate. Regular calibration ensures that the hardness comparison plates maintain their certified accuracy and that the testing equipment operates correctly. Typically, international standards provide guidelines for calibration.
Recalibration of hardness comparison plates
We recalibrate your hardness comparison plates from all manufacturers within one week with a DAkkS certificate, ensuring that you can always perform precise testing.
Correct use of hardness comparison plates
To ensure that you can reproduce the calibrated hardness value as accurately as possible, you should handle the hardness comparison plate with the same level of care.
This starts with proper storage: Always store the hardness comparison plate in its box. Even the smallest scratches or corrosion can affect test results. Such damage cannot be corrected by grinding or polishing. A plate that has been treated in this way can no longer serve as a reference.
The right hardness comparison plate for the testing method
Make sure to use a hardness comparison plate that is suitable for the specific testing method. A color-coded and symbolic labeling system on the packaging will help you avoid confusion.
Keep the working environment and the hardness comparison plate as clean as possible. The testing surface and the machine table surface must be free from grease and dust. Again, even the smallest particles between the test indenter and the hardness comparison plate, as well as between the plate and the support surface, can affect the test results.
Pay attention to the distances between the test indentations
Of course, you want to use your hardness comparison plate as economically as possible. Due to structural changes in the area of the indentation, it is essential to maintain the minimum distance between indentations as well as the distance to the edges.
By adopting this approach when handling your hardness comparison plates, you can efficiently use the plate for periodic, daily checks with your hardness testing equipment, thereby ensuring precise test results.
