Frequently asked questions about our materials testing laboratory
What added value does the imprint process offer compared to other processes?
- Low Destruction
- Accurate testing of the 0.2% yield strengthRIp0.2* and the tensile strength RIm*
- Test points with small dimensions testable
- Determination of local flow curves as a basis for FEM simulations
Which materials can we test for you in our materials testing laboratory?
In principle, we can carry out materials testing for all metals (steel, nickel, aluminium as well as titanium and copper materials) - contact us individually about your materials to be tested. Or inform yourself here.
Does the sample or component have to meet certain requirements?
The sample to be tested should have the following characteristics:
- Component height not higher than 350 mm
- Upper and lower surface are plane-parallel, or must be suitable for preparation
- For optimum results: Inclination of both sides is a maximum of approx. 2%
In which load ranges can be tested?
We test in the range from 150kg to 5kg, which means that thin sheets can also be tested, for example.
On request, tests with individual load levels can also be realized.

State-of-the-art technology in the Imprintec materials testing laboratory:
Low-destructive and pinpoint materials testing with the indentation method according to DIN SPEC 4864
Until now, anyone who needed information about the quality, condition or suitability of a material for a particular application was faced with the challenge that a hardness test alone did not provide all the important characteristic values and the conversion table for hardness values and tensile strength according to DIN EN ISO 18265 could only be used with restrictions. A tensile test that provides detailed information on the material must be prepared at great expense and leads to the destruction of the sample.
In the Imprintec materials testing laboratory, our specialists work with the innovative and patented indentation method according to DIN SPEC 4864, with which just one measuring point provides the desired mechanical characteristic values (RIp0.2* and RIm*).
Comparison characteristic values according to DIN SPEC 4864 for Rp0.2 and Rm from the tensile test
The benefit of laboratory testing with the indentation method lies in the combination of local and meaningful testing of the strength values 0.2% yield strengthRIp0.2* and tensile strength RIm*. In many cases we can support you in the development and quality assurance of your components. This provides you with a solution for testing your parts where you have not been able to take tensile specimens up to now or where the missing statement on the 0.2% yield strength Rp0. 2 and tensile strength Rm for different metals is not covered by hardness conversion.
