Mechanical and mechanical-technological tests
The determination of strength, stiffness, toughness, ductility or hardness is of considerable importance for the application-related behavior of a material or product. Various methods can be used to characterize material properties or to check the final product characteristics. Some mechanical test methods can also provide information on several properties at the same time. For example, tensile tests can be used to determine both tensile strength and characteristic values such as modulus of elasticity, yield strength or elongation at break.
The following mechanical tests are carried out particularly frequently as part of plastic characterization:
- Tensile test
Determination of tensile strength, modulus of elasticity, yield strength, elongation at break and other material parameters - Compression and bending test
Determination of compressive strength and flexural strength - Impact and notched bar impact test
Determination of the resistance of a specimen to an impact or high-speed load - Dynamic tests
Determination of mechanical properties under periodic loading
(e.g. bending, tension, shear or compression)

- Sample preparation
The correct preparation of the samples is crucial. Different sample shapes or sizes can lead to different results. - Specimen condition
The physical condition of the sample (e.g. degree of criticality or residual stress level) can influence the results. - Temperature and humidity
Both the ambient conditions (temperature and/or humidity) and the water content of the samples themselves can influence the tests. - Calibration
Accurate calibration of the testing machines is crucial to obtain accurate measurement results. - Sample ageing and storage conditions
The storage conditions of the sample prior to testing can influence the results. Ageing effects of the samples can also lead to changes in the mechanical properties.
