Do you need to assess the mechanical properties of materials and components? Tensile testing measures the strength and stress resistance of a material when subjected to a tensile force. The test is performed both in the standardized version (most often according to EN ISO 6892-1) and for atypical samples including non-standardized measurement procedures (e.g. testing of bonded and soldered joints, very thin profiles, wood, composite polymer materials, etc.).
TENSILE TESTING
Tensile Tests for Standard and Non-Standard Specimens
Tensile testing and its course
The principle of the tensile test consists in exposing a material sample to a gradually increasing tensile force up to the point of its failure. During the test, the force applied to the sample is measured, while the elongation or deformation of the sample is monitored. The obtained force and deformation values are used to create a tensile diagram that displays the relationship between the stress and strain of the material.
Tensile Testing Equipment
Two measuring devices are available for testing – up to 100 kN we use the ZD 10/90 universal tensile testing machine, and up to 1,000 kN we use the ZD 100 universal tensile testing machine. Since these are universal machines, simple modifications using testing fixtures allow for other measurements to be performed, such as static bend tests, static compression tests, spring testing, dynamic tests, etc.
Production of Test Specimens
A newly built machining center is located on the laboratory premises, where we are able to manufacture test specimens from the supplied material precisely according to your required standard or procedure. The machine tools are operated by personnel with many years of experience and qualification. We are able to complete the production of test specimens by the next day after receiving the supplied material. After the test is performed, it is possible to arrange for the archiving of the test specimen and the semi-finished product for a pre-determined period.
Tensile Test – Specimen Specification
Tensile tests are performed on test specimens of full cross-section, e.g., tubes, wires, and rods of smaller dimensions, on machined specimens of rectangular or segment cross-section strip types, and on circular cross-section specimens. The length of the test specimen, including the ends (so-called heads) for gripping in the testing machine, must correspond to the size of the tested cross-section. If enough material is available, a specimen length of 300 mm in the tested direction will be sufficient for most applications.
Certificates and Contact
The requirements for testing equipment, types of test specimens, and testing procedures are determined by the standard. For certain testing cases, the laboratory also refers to the relevant special standards. The output of the tests is an accredited test report in Czech and in your requested language.
The list of testing procedures for which the laboratory is accredited can be found in the appendix to the certificate. If you are interested in this test, please do not hesitate to check our contact information and get in touch with us.
