Application
Whether standardized or customer-specific, Pollux Testing offers you the optimal solution for your requirements
We offer you the entire spectrum of testing services: from normative test conditions (LV124, VW 80000 BMW, GS 95024-3-1, CS.00056) to investigate climatic requirements or service life testing to special tests tailored specifically to your prototypes.
Lifespan testing and climatic requirements
In our test laboratory we carry out all common service life tests such as high and low temperature endurance tests or temperature change tests for you. But we can also carry out tests to validate climatic requirements (high/low temperature storage, step temperature tests or thermal shock tests) for our customers.
Conditioning systems from Pollux's own development are used, which can provide both water- and oil-based media in the range from -40 °C to 140 °C with the highest control quality. The use of special media is also possible.
Our climate chambers simulate ambient temperatures from -70 °C to 180 °C, at different humidity levels.
Bidirectional power supplies with up to 1500 V and up to 1000 A are available in various performance classes for electrical components. If you need higher voltages or currents for your desired test application, please feel free to contact us. Together we will find the right solution for you.
Our range of services is rounded off by our fully automated and flexibly adaptable test bench software, so that our powerful testing laboratory leaves nothing to be desired.
Overview of standardized test scopes
LV124: Climatic requirements and tests
- K-01 high/low temperature storage
This test serves to prove the storage and transportability at particularly low or high temperatures. The test can also be used to bring the components to be tested to the same initial state (pre-aging). The test is considered passed if the test items are fully functional before and after storage. Proof is provided by a large parameter test.
- K-03 Low temperature operation
The test conditions serve to ensure the component function after long periods of standstill or driving at extremely low temperatures. Continuous monitoring of all important specification parameters as well as a final parameter test (small) must be passed to prove functionality.
- K-13 temperature shock diving
This thermal shock test simulates immersing a heated component in cold water. The parameters required to demonstrate functionality must be continuously monitored and checked before and after the test using a small parameter test.
- K-02 step temperature test
The test conditions simulate operation at different ambient temperatures. The temperature range from the minimum to the maximum operating temperature is examined in steps of 5000. A subsequent parameter test (functional test) is used to check the full functionality of the tested components.
- K-05 Temperature shock (component)
The test conditions simulate the shock-like temperature changes between minimum and maximum permissible operating temperatures that occur during driving. The test serves to protect the components against thermally caused cracks. Proof is provided by a parameter test (large).
- K-16 temperature shock (without housing)
This test examines individual housing-less assemblies of the component and therefore does not represent any real stress. The aim is to identify weak points in the mechanical connections of the assemblies. The test conditions range from minimum to maximum operating temperature. Proof of full functionality is carried out using a large parameter test.
LV124 (LV150): Lifespan tests
- L-02 High Temperature Operating Endurance (HTOE: High Temperature Operating Endurance)
The test parameters simulate the thermal stress over the entire service life of the vehicle. The reliability of the component is checked against thermally caused defect patterns such as diffusion, migration or oxidation.
As proof of functionality, large parameter tests must be passed before and after the test as well as at 25%, 50% and 75% of the test runtime.
- L-03 Temperature cycling endurance test (PTCE: Powered Thermal Cycling Endurance; Thermal Stress Test)
The temperature changes between minimum and maximum operating temperature simulate the thermomechanical load over the entire service life of the vehicle. Particular attention is paid to the aging-related cracking of soldered, adhesive or welded connections as well as between seals and the component housing.
As proof of functionality, large parameter tests must be passed before and after the test as well as at 25%, 50% and 75% of the test runtime.
LV124 (LV150): Electrical requirements and tests
- E-15 Polarity (Reverse Polarity)
The test conditions simulate the resistance of the component to the wrong polarity connection of a battery, for example with external starting aid. Reverse polarity can occur several times and must not lead to any damage to the component even with minimal voltage. The vehicle fuse is not part of the reverse polarity protection concept. Before the start of the test, a small parameter test must be carried out, and after the test has been completed, a large parameter test and a physical analysis of the test specimen must be carried out in order to provide proof that the test has been passed.
LV124 (LV150): Parameter tests
- P-01 Parameter test (functional test)
This functional test is used to evaluate the key parameters at a specified temperature at the voltages UB_min, UB_nom and UB_max. The basic functionalities of the components are measured and, if available, the error memory is read.
- P-03 Parameter Test (Large)
This extensive functional test evaluates key parameters and the functional behavior of the components at maximum and minimum operating temperatures as well as room temperature at the voltage levels UB_min, UB_nom and UB_max. Furthermore, the components are subjected to a visual inspection in accordance with DIN EN 13018 and examined for external damage and changes such as cracks, splitting/flaking, discoloration, deformation. The components remain unopened. Finally, the inside of the component is checked for loose parts using a shaking test. Changes in the values of the key parameters, the functional behavior or the error memory entries as well as abnormalities in the visual inspection are compared with the new condition and evaluated.
- P-02 parameter test (small)
This functional test evaluates key parameters and the functional behavior of the components at room temperature and operating voltage UB_nom. In addition, the error memory is read out. In addition, the components are subjected to a visual inspection in accordance with DIN EN 13018 and examined for external damage and changes such as cracks, splitting/flaking, discoloration, deformation. The components are not opened. A subsequent shaking test detects possible loose parts inside the component. Changes in key parameters, functional behavior or error memory entries as well as abnormalities in the visual inspection are compared with the new condition and evaluated.
