Accredited test procedures
Our Test Centre is accredited for selected tests by the Deutsche Akkreditierungsstelle GmbH (Germany’s national accreditation body – DAkkS) according to DIN EN ISO 17025. We offer material testing engaging the highest internationally recognized quality standards. Our services include quasi-static, tests and determination of physical properties of fibre-reinforced composite materials and plastics. Through regular assessments, we ensure the competence and quality of our test laboratories. On request, tests can be transferred to the accredited laboratory, or the accreditation can be realised by our customer.

Standardised test procedures
Our laboratory offers a wide range of tests according to national and international standards for all kinds of industry. Our team possesses extensive experience in performing standardised tests on almost all modern material classes. For mechanical tests, we use classical deformation measurement methods (such as strain gauges) as well as advanced optical measurement methods (for example greyscale correlation). Almost all experiments can be performed at defined temperatures (-60 °C to 250 °C) and climates. For determination of physical properties such as the thermal or rheological behaviour, we use various methods, for example DSC, TGA or plate rheometer. We proof our qualifications through regular participation in round robin tests.

Innovative test procedures
The rapid and dynamic development in the lightweight engineering sector increasingly calls for the application of special tests for determining specific material characteristics. Due to the increasing complexity of design and simulation criteria, input parameters, surpassing the classical material properties such as strength and stiffness, are required. The high demands on the quality of results require the continuous development and improvement of established procedures. Using current scientific knowledge, we offer customised solutions for your problems.
- Conception, design and detailed construction of test devices
- Numerical preliminary examinations and test related simulation
- Definition of evaluation methods and routines
- Development of specimen geometries for generation of defined loading conditions and failures
The design process is based on the knowledge of failure and damage phenomena occurring in the material, especially when using modern lightweight materials and connection techniques. Our laboratory provides services to test your materials in accordance with current national and international standards or according to customer requirements. Furthermore, we can determine material characteristics, which go beyond the classical material properties such as strength and stiffness.
- Fibre-reinforced composites
- Joint connections such as adhesive bonds, clinch sealings and welds
- Special materials such as foams or honeycombs
- Hybrid structures such as sandwich composites
Accompanying the performed characterisation tests, we also offer modelling of the material behaviour. The FE-based simulation of the experiment increases the understanding of the measured data. In this way, the damage history can be traced. Furthermore, we can implement a computer-aided design of your components with the material cards created and validated for you.
- Generation of material cards
- Validation of material behaviour
- Virtual testing
- Design of components
- Validation of components
Component and system tests
The implementation of experiments for the validation and admission of components and systems is the final step of each development process. Therefor we provide support for conception, design and detailed construction of test rigs. With our vibration decoupled clamping field, we can implement all your test requirements for static and cyclic testing. For the testing of components from aerospace, automotive and marine industries, we offer a wide range of customised test benches which can be adapted to our customers’ requirements if necessary. Furthermore, diverse climate and pressure chambers for the test procedure and specific climatic change tests can be used.

It is not always expedient to perform destructive tests on specimens. Non-destructive test methods have been established especially in the area of quality assurance and damage detection. Through these test methods, externally invisible defects and the internal structure of the material can be analysed without damaging the specimens. Certain methods can be carried out in combination with a destructive test, which allows more detailed conclusions concerning the failure behaviour. We master a wide range of non-destructive testing methods; therefor we offer a comprehensive review of manufacturing processes, determination of damage incidents and measures of quality assurance.
- Ultrasound (air and water coupled)
- 3D-digitisation (ATOS®)
- CT and In-situ CT
- Optical microscopy and scanning electron microscopy
The following methods can be used when performing destructive tests to increase understanding of the material behaviour.
- Acoustic emission analysis
- In-situ CT
- Optical microscopy and scanning electron microscopy
The quality of measurement results depends to a large extent on the quality of the specimens. Through our extensive experience in the area of processing of plastics and composites, we offer qualified support in producing auditable structures and specimens. For cutting operations, e.g. water jet cutting, laser cutting or milling, we closely cooperate with reliable regional partners.
