expertise regarding resistance, strength and reliability studies on standardised samples up to, and
including, complex components. Verifying the reliability and safety of the material for the service life
of a component with a wide variety of types of load is a demanding task – for us it is a core competence.
Positioned between research and industry, we dedicate ourselves, for example, to face Questions about
the crack propagation behaviour with regard to lightweight construction materials or the comparative
characteristic profile of parts made from additive and conventional manufacturing.

Our engineers will be pleased to support you during the implementation for your testing programs as
well as assisting with the standardisation, approval and certification of materials or manufacturing processes.
We are also available to assist you throughout the entire testing process. Starting with consulting, test
planning and manufacturing samples through to testing and on to the finished test report and supporting
you moreover with the optimisation process. The test spectrum of our accredited laboratories covers
all industrial sectors.

We work according to German and international standards and guidelines (DIN, ASTM, ISO, etc.),
or in accordance with factory settings. Our test laboratories are accredited according to
DIN EN ISO/IEC 17025 for mechanical and technological testing and moreover are accredited for
the business fields of “Material Testing of Metallic Materials” and “Material Testing of non-metallic
materials according to SAE Aerospace Standard AS7003 by NADCAP” (National Aerospace and Defence
Contractors Accreditation Programme).

Investigation of the material properties

We assume the comprehensive determination for your material parameters as well as evaluating the
loading capacity of metallic materials, jointed connections or hybrid material combinations.

Depending on requirements or specifications involved, tests can be executed at lower and higher
temperatures as well as media influence supported. We provide comprehensive standard testing and
measuring equipment for material and component testing.

You can also benefit from our years of experience in design and application of special test rigs.
Please contact us if you Need a customized solution for your testing requirements. Our experienced
engineers are at your disposal for advice. The preparatory discussions are of course free of charge.


At the beginning of a design phase, the question of the choice of material selection is raised comes to the fore.
The selected material forms a basis and must withstand a wide variety of the most diverse and complex stresses
in later use. Materials testing offers you the an ideal basis for determining the material performance capacity
that the material must have provide for your project.


Here you can find the standards of mechanical-technological tests.

Fracture mechanical testing

In general fracture mechanical investigations enable a quantitative description of the material damage
behavior caused by crack initiation and crack propagation by means of continuum mechanical failure analyses.
In order to fully exploit the potential of new or already existing engineering materials, it is necessary to apply
already existing calculation and testing methods or to develop new testing methods which can represent the
behavior of a component under real-time operating loads and stresses to the greatest possible extent and
ensure sufficient safety against the various possibilities of failure.. Especially in view of the increasing safety
requirements, but also with regard to the economic efficiency and conservation  of resources, an exclusive
design of components and structures on the basis of classical science of strength of materials
(i.e. without considering defects in the material or component) is no longer up-to-date.

On the contrary, cracks which could occur either as a result of the manufacturing process or by stress or
during operation must be considered in the design. The evaluation of cracks and/or crack-like imperfections
in construction parts and components is indispensable for determination of fracture mechanical parameters
such as, for example, the threshold value behavior or the crack resistance behavior as the fracture mechanical
analysis of fictional and real existing cracks must be increasingly considered as an additional safety factor
in the component design process.
