Temperature and climate tests
As part of a solar weathering test, a sun-like radiation spectrum from the ultraviolet to the infrared range is generated using a metal halide lamp. The solar simulation chamber affects the test object with both short-wave and long-wave radiation. While the short-wave components have a destructive effect on atomic bonds that should not be underestimated, the long-wave components can lead to a strong heating of the irradiated bodies and thus to thermal defects.
This makes it possible to simulate the effects of light on the test specimen under laboratory conditions, and to investigate degradation effects caused by exposure to changing sunlight, temperature, humidity and rain.
Tests with solar simulation are recommended for products that are exposed to solar radiation outdoors as well as inside vehicles or buildings.

Video: Salt spray test |
|
The salt spray test is a standardized method for evaluating the corrosive influence of saline solutions on coatings, metallic coverings or various surface treatments. The influence of humidity, oxygen and salts, for example in metals, leads to the formation of metal oxides by means of a redox reaction. The corrosion not only affects base metals, but also higher-alloyed, tempered materials.
This test is particularly useful when products are used on winter roads, on the high seas or near the sea. The salt spray test is now part of the standard testing scope for products used in vehicles. The running time of a salt spray test is typically in the range of 96 to 240 hours.
Therefore, the test is particularly sensible for products which are used on the high seas or near the sea. In the automotive sector, the salt spray test is now part of the standard test scope.
The test item is placed in the test chamber and exposed to a salty fog atmosphere. A simulation of stress on the test item caused by salt solutions, comparable to conditions in road traffic, is shown. Run times of a salt spray test range from about 96 to 240 hours.

The use of materials which are based on organic compounds such as plastics and adhesives involves certain risks due to the problem of outgassing.
By carrying out an outgassing test, the effects that only occur after a longer period of time in normal use of the illuminants and products can be revealed in a short time. The outgassing behavior of materials, components and complete modules is fully investigated. In addition, we offer material tests with customer-specific test temperature and test duration.
For this purpose, the test specimens are heated in a chamber and the outgassing substances are detected on a test plate.
Our range of services thus includes outgassing tests on lamps in accordance with:

Many technical products are used in environments over the course of their service life in which they must regularly withstand large fluctuations in temperature and humidity.
Our climate tests are suitable for representing such environmental influences as well as high and low temperatures, temperature changes and extreme humidity.
As part of the climate investigation, combined temperature and humidity tests can also be carried out in combination with vibration if required. In addition to time-lapse test programs, control, operation and monitoring of the test objects, for example for durability tests, are also offered.
The results of the study are used to optimize the durability, reliability and performance of the products.

Temperature shock testing is used to test the resistance of components, devices and other products to rapid changes in ambient temperature. With our temperature cabinets, the ambient temperature can be changed by over 200°C in just a few seconds.
The test specimens are cyclically exposed to rapid temperature changes in air. Different thermal expansion coefficients and different thermal paths then lead to mechanical stress on the test specimens and to their degradation. This makes it possible to identify structural weaknesses in the test specimen.

During humid storage, also called condensation testing, sample specimens are exposed to a climate with 100% relative humidity.
This allows the formation of condensate on the surface of the test specimen in the test chamber.
The test serves to clarify the behavior of the test specimens in highly humid climates (swelling behavior of plastics), allows conclusions to be drawn about the performance of corrosion protection and enables the detection of possible coating defects.

IP ingress protection types
Depending on the installation location and conditions, electrical and electronic devices are protected with a housing against the ingress of dirt, dust, water or even body parts and objects in order to prevent danger to people or failure, e.g. due to water, corrosion or possibly conductive dirt.
The IP code, which stands for the IP protection class, is made up of two code numbers. These provide information about the degree to which the device is protected from external influences.
The first digit describes the protection against the ingress of foreign bodies, body parts and dust and ranges from no protection (IP0X) to complete protection against contact and dustproofness (IP6KX).
The second digit represents the degree of protection against the ingress of water. The protection ranges from no protection (IP0X) to protection against high pressure (IP9KX).
When determining a protection type, the first and second digits are checked one after the other.

In addition to the salt spray test and the condensate test, the corrosive gas test is a third form of corrosion test. Products to be tested are exposed to an atmosphere with defined amounts of aggressive gases, such as those that can also occur in the normal operating environment.
According to the frequently used test standards, corrosive gas tests can be carried out with just one type of gas, as well as tests with up to four types of gas at the same time.
Available gases for these tests are sulphur dioxide (SO₂), nitrogen oxides (NOx, NO₂), hydrogen sulphide (H₂S) and chlorine gas (CL₂).
Concentrations between 5 ppb and 50 ppm and ambient temperatures of up to 40 °C and a relative humidity of up to 95 percent are set. Corrosive gas tests can be used, for example, to check contact corrosion on electrical components such as circuit boards or similar.

Splash water tests are used to prove the insensitivity to thermal shocks (air to liquid) of components and systems located in the surge area of a vehicle. In addition, the tightness of housings or encapsulations is checked.
This method simulates, for example, driving through a puddle in winter, when the part to be inspected is at a high temperature due to the surrounding motor and then is immediately cooled by the water. The water is tempered to a temperature of 0 to +4°C, while the part to be tested has been brought to a high temperature (e.g. +160°C).
Here, the effects of the alternating expansion of materials are tested, whereby the penetration of water is just as much a part of this as the function of the device.

Video: Vibration test |
|
A product is subjected to various mechanical stresses during each phase of its product life cycle, which can lead to a change in materials, severe damage and consequent failure of the product. This can affect both transportation and normal operation. To ensure that the product can withstand the stresses, these are simulated by vibration testing. Electrodynamic shakers are therefore used to induce vibrations within the component during vibration and modal analyses. In addition, they are used for fatigue tests where high frequencies have to be induced.
The induction modes are divided into sine stimulation (deterministic algorithmic vibrations), random or noise stimulation (stochastic vibrations), and shock stimulation (single shock or impact).

The test of the gravel impact resistance of coatings carried out in accordance with DIN EN ISO 20567-1 is considered a multi-impact test. The gravel impact test is a standardized test method for investigating the durability of coatings and is required by vehicle manufacturers in a wide range of standards.
In the standard-compliant multi-grit tester, coated test items are bombarded in rapid succession by many small sharp-edged impact bodies, a standardized chilled cast granulate. The bombardment material is accelerated by compressed air at a specified angle onto the test item. The gravel impact resistance is then assessed.

High-speed recording enables the exploration and study of high-speed process flows.
The Keyence "VW-9000" high-speed camera has a wide range of dynamic recording options. Applications of the innovative Keyence camera include recording the vibration behavior of a test item on shakers when attention is to be paid to mounts, specific fixing points or connections. Furthermore, recordings of an impact during a drop test, as well as of shock pulses are conceivable.
In addition to a macro lens with 6x optical zoom, the high-speed camera offers colour images instead of conventional black-and-white images. A free angle adjustment of the tripod allows mobile applications of the camera. An integrated illumination unit that can be adapted to any application situation produces high-quality images, and there is also a full-frame scanning system. Frame rates can be up to 230,000 fps.

Tension/compression tests can be used to determine how components or connectors, for example, react when subjected to a sequence of compressive and traction.
Mechanical tests such as tension, compression and bending, as well as the determination of insertion, withdrawal and retention forces, can be applied to materials and components in a variety of ways.
The test items are loaded by the test variables force, moment or deformation with defined value, time sequence and defined frequency. Tension, compression and flexure tests based on various test standards are distinguished as classic test types.
With our tension/compression tests, we offer strength and component testing in the load range up to a maximum of 5 kN. Clamping tools and test equipment are available for statistical and dynamic tension tests, statistical and dynamic compression tests, and bending tests.

Video: transport simulation/packaging testing |
|
The aim of the transport simulation and packaging test is to simulate the transport load on the type specimen on its way to its subsequent place of use by means of suitable test procedures from the field of vibration testing and environmental simulation. Be it a load caused by transport on rails, the road or extreme conditions of a sea transport or an air transport, the test should show in which condition the test item arrives at its destination. It also checks whether the packaging protects against damage and thus meets the requirements.
Results that can be shown on the basis of the simulation reduce the risk of transport damage and minimize costs associated with damage. Through simulation, we make the environment calculable for you.

Video: shock test |
|
By carrying out shock-like loads and thus mechanical shock tests, the aim is to test conditions on objects that can occur during transport or later use of the objects. In almost every phase of the product life cycle, mechanical shock loads occur that can lead to product failure. The focus of the test is on any deterioration in the test specimen's properties, on the assessment of the constructive execution or the dynamic behavior.
This generally results in significantly higher loads than with classic shocking on an electrodynamic shaker. Very high accelerations of up to 20,000g can be achieved using a shock amplifier.
Early testing enables the lifespan of a product to be assessed.

Electronics and software have become indispensable components in the automobile. The verification of development results therefore includes not only the mechanical systems, but also the electronic control units and their software. The complexity of the highly networked systems places high demands on the test process and the test tools. Systematic and comprehensive tests are necessary in all development phases.
Electrostatic discharges, or ESD for short, cause a short, high electric current and can cause soaps to ignite. Under certain circumstances, in addition to a fire and explosion hazard, there is a risk of damage to electrical components in equipment. The ESD 30N is an ESD test generator for simulating ESD pulses for higher voltages up to 30kV for air and contact discharge. Simulation testing applies to equipment exposed to discharges of electricity due to environmental and installation conditions.
The ESD 30N test equipment significantly exceeds the requirements of EN/IEC 61000-4-2 and for automotive test applications.

Photobiological evaluation
With the help of versatile spectrometers we can perform radiometric evaluations of light sources and headlamps according to ECE regulations (k1, k2, kuv, kred) as well as a classification according to IEC 62471 - photobiological evaluation of lamps and lamp systems.
Irradiance or radiance measurements in the ultraviolet, visible and infrared range provide them with information about the spectral composition of their light or radiation sources. The determination of reflectance or transmittance properties of different materials (e.g. lamp bulbs, headlamp lenses, reflectors, ...) complete our portfolio.
Through active cooperation and development of internationally recognized norms, standards and other committees, we can provide you with expert advice and plan the optimal measurement together with you.
Test standards:
- ECE R37, 99, 128
- IEC 62471

Video: Coordinate measurement |
|
A coordinate measurement is the acquisition of spatial coordinates of points on a workpiece surface. The measuring points are further processed and the values of the selected, assigned, geometric quantity are calculated.
Our Zeiss Contura is a coordinate measuring machine of the gantry type and has two optical sensors in addition to a tactile sensor. When measuring a wide variety of products, for example, the actual values of inspection characteristics such as distances, diameters or defined heights are compared with specified customer requirements as well as specified standards. These measurements are used to ensure the accuracy of fit of products. In addition to the flexible scanning of individual points, the non-contact acquisition of several thousand measuring points is also possible. Depending on the sensor and the measurement job, the measurement uncertainty is around 1-2μm. Furthermore, product-specific measurement programs can be created and evaluated for our customers.
Within the scope of the inspection equipment monitoring, a periodic DAkks calibration of the coordinate measuring machine takes place. Through the additional daily measurement of connection standards, we ensure the stability of our measuring systems and thus offer precise geometric measurement results for you as a customer.

As the most important tool in quality assurance, microsection analysis allows an evaluation of soldering and joining parameters already in the product development process and is, thus, suitable for the optimization of process parameters. In addition to determining layer structures from the bonding or coating process, a cross-section enables the detection of the formation of intermetallic phases in the soldering process.
In mechanical joining processes such as press-fitting, riveting or hot caulking, cross sections can be used to check geometry specifications as well as the position and connection of the components involved.
In the field of failure analysis, cross-section analysis is also a valuable tool for identifying defective, "cold" solder joints, insufficient solder wetting or solder penetration. Material stress or pre-damage such as over-expansion, formation of grain boundaries and embrittlement can be agnosized by means of metallographic microsection analysis in combination with contrast-enhancing etching.
Our X-Ray, an automated X-ray system tested and approved by the German Technical Control Board (TÜV), scans and analyzes a wide variety of components in real time for damage and cracks. For example, solder joints are checked for voids or the position of pins in the plastic is assessed. With the built-in laminography function, it is also possible to record components in several different sections. This advanced X-ray analysis makes it possible to specifically inspect components for changes or damage during and after the validation process in order to confirm the proper functioning of electronic products, for example.
