Parts and components are exposed to various environmental stresses. With test chambers we simulate various climatic conditions in advance and use stress tests to check whether the function of a product is impaired. We assess surface properties and check surface coatings for their protective function against corrosion, UV radiation, mechanical stress and its media resistance.
Testing the corrosion resistance of components and technical products is an essential verification of the quality of materials and electroplated coatings. High resistance to corrosion must also be demonstrated for specific corrosion protection packaging and films, for example for metal and electronic products, as well as for licence plates, badges and adhesive seals.
With tests in the salt spray chamber, material testings can be carried out according to a wide range of national and international standards as well as customer specifications.
During their service life, components and coatings may be exposed to corrosive environmental conditions. Corrosion tests are intended to reproduce the corrosion process in nature in a short time. We simulate these corrosion conditions in advance. In doing so, we check whether the function of your products is impaired. Materials or components are exposed to a corrosive atmosphere in test chambers.
The test spectrum includes combined corrosion change tests. Changes in salt concentration, air humidity and temperature cause the corrosion environment on the material or component to change repeatedly. Condensation water tests are also used to clarify the behaviour and detect defects in the corrosion protection of the test specimens in humid environmental climates.
The DEKRA materials laboratory in Saarbrücken is also approved by DIN CERTCO as a testing laboratory for retroreflective number plates. After successful testing, you will receive the DIN testing and inspection mark.
Products, coatings, packaging and labels are often exposed to challenging environmental conditions during transport and use. High resistance to temperature fluctuations, humidity or UV radiation is therefore required.
We use climate tests to simulate the long-term behaviour of components under harsh environmental conditions in order to uncover any weaknesses and avoid damage, failures and complaints.
Parts, assemblies or technical products are exposed to a variety of environmental influences during their service life, which may have a negative impact on function and appearance, and can reduce the service life. Packaging or labels and seals used for the transport and identification of products and machines can also be negatively affected by environmental influences.
Stresses in the plastic under the influence of heat may lead to distortion of the component (deformation) and thus to problems regarding the accuracy of fit within an assembly. Especially with frequently changing temperatures, simulated by temperature change tests, cracks or material detachments can occur. Brittleness of the material or a change in the mechanical strength can also often be observed.
In test chambers with artificial atmospheres, DEKRA experts simulate stressful environmental conditions and test the climate resistance of your products and packaging. The test spectrum includes combined cyclic corrosion tests, temperature-climate change tests and UV weathering tests.
The surface of components and especially their coating must often withstand extreme stresses, such as UV radiation or mechanical loads. In our laboratories, we carry out characterisation and resistance tests for properties such as coating structure, adhesive strength and hardness. We also test surface roughness, coating thicknesses and media resistance.
For industrial components, consumer goods and automotive parts, we help you to ensure the surface quality and functional properties of your products and coating systems. In our accredited laboratories, we carry out tests according to international standards as well as according to the requirements of car manufacturers. Our experts assess the surface resistance to environmental conditions, chemicals (media resistance) and abrasion.
