TEMPERATURE SHOCK TESTING AND THERMOSHOCK TESTING
Temperature shock testing (thermal shock or also thermal shock testing; related standard: DIN EN ISO 60068) is a variant of thermal cycling. In this variant, a component is subjected to strong temperature differences in a very short time. This can cause unacceptable metallurgical changes to the component or to the adhesive strength of coatings.
With many years of experience, especially with regard to the requirements in the automotive industry and medical technology, we perform environmental and climatic tests for our customers according to customer specifications and in strict compliance with applicable standards.
What tests can we perform?
Here you will find an overview of the most common tests we offer in the field of environmental simulation in our test laboratory. In addition, we can offer a variety of other tests.
Temperature cycling (according to DIN EN 60068-2-14)
Cyclic change between two defined temperature upper and lower limits to simulate the life cycle of components.
Rapid temperature change (according to DIN EN 60068-2-14 Na, transfer duration < 15s).
During rapid temperature change or temperature shock according to DIN EN 60068-2-14, the test specimens are subjected to very rapid temperature changes.
Cold (according to DIN EN 60068-2-1)
This test is used to test the utilization of one-sided loads with a defined cold.
Heat (according to DIN EN 60068-2-2)
This test is used to check the utilization of one-sided loads with a defined heat.
Humidity-heat constant (according to DIN EN 60068-2-30)
In this test, the test specimen is exposed to a defined high humidity at a defined temperature.
Humidity-heat cyclic (according to DIN EN 60068-2-38)
In this test, the test specimen is exposed to a defined high humidity at alternating temperature cycles.

Environmental simulation with condition monitoring
In a temperature shock test, test specimens are repeatedly subjected to defined temperature changes (called temperature shocks) to test the effects of the temperature changes on the test specimens.
Frequent repetitions of these temperature changes reveal weak points and environmental influences that occur in the field during development or production in a specific temperature range and under extreme weather conditions.
Thermal shock testing (thermal shock or also thermal shock testing; related standard: DIN EN 60068 2) is a variant of thermal cycling. In this variant, the components are subjected to strong temperature differences, a so-called thermal shock, in a very short time.
Are measurement data recorded during the test?
With the measurement systems available in our test laboratory, we can monitor, store and evaluate a wide range of electrical parameters during the individual cycles of the test. Targeted excitation of specific behaviors of the DUTs during the tests is also possible
What does the test environment in the test laboratory look like?
We use equipment from the company CTS for our tests. For thermal shock testing, we use 2-chamber air-to-air systems that have a test chamber volume of up to 130 liters with a maximum chamber load of 25 kg. The temperature range of the hot chamber is 50°C to 200°C, in the cold chamber temperatures of up to-80°C are reached.
