Environmental simulation tests and further simulations for assemblies

In an environmental simulation, assemblies are subjected to defined environmental conditions to validate their behavior under those conditions. The variables of an environmental simulation test include climatic aspects such as temperature (cold, heat), the air conditions (humidity, wetness), mechanical influences such as dust, vibration, vibration or impacts, and corrosive environmental effects such as salty lift (salt fog).

As an environmental simulation laboratory, we simulate these environmental conditions in our climatic chambers and climatic chambers, creating real conditions to investigate the long-term behavior of the test specimens in reality.

Temperature Shock Testing/Thermal Shock Testing

.
The temperature shock test is an essential part of an environmental simulation. In a thermal shock test, specimens are repeatedly subjected to defined temperature changes (called temperature shocks) to test the effects of the temperature changes on the specimens. Frequent repetitions of these temperature changes reveal weak points and environmental influences that occur in a specific temperature range and under extreme weather conditions in the field during development or production.

Temperature cycling

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.

Temperature cycling (according to DIN EN 60068-2-14)

Cyclic change between two defined temperature upper and lower limits to simulate the life cycle/lifetime of the 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.

Are measurement data recorded during the environmental simulation?

With the measurement systems available in our laboratory, we can monitor, store and evaluate a wide range of electrical parameters during the individual cycles of the environmental simulation. Targeted excitation of specific behaviors of the DUTs during the tests is also possible. Within the scope of validation or qualification, we enable electrical condition monitoring of the DUTs after prior consultation with you and according to your specifications.

What is the test environment for environmental testing and environmental simulation?

We use equipment and testing technology from CTS for our environmental simulations and all other tests. For thermal shock testing, we use 2-chamber air-to-air systems (climatic chambers)which 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, while temperatures of up to-80°C are achieved in the cold chamber.

Other services in our Testing & Checking division

In addition to the tests listed above in the field of environmental simulation, we offer a variety of other tests up to complete validations of electronic and mechanical assemblies. With our test methods, we make the effects of various weather conditions measurable and uncover weak points in durability under previously defined test temperatures.
