Environmental Simulation

Expert knowledge on environmental simulation

A wide range of test methods are applied in environmental simulation in order to identify how an object or living system interacts with the expected environmental conditions.?

These conditions are simulated in fast motion. In other words, the test parameters are set based on certain guidelines, such as the "Good Laboratory Practice", so that they correspond to the actual stress that would be applied over a longer period of time, which is often equivalent to a year. It goes without saying that measuring this test period is also an expense, which is to be taken into consideration with the acquisition of new measuring technologies.?

The aim of environmental simulation is to analyze the sometimes complex network of causal chains as comprehensively as possible. Therefore, environmental simulation is mainly used to reveal causalities and to depict these as models.?

Environmental simulations set high expectations on the measuring technology used and demand a high degree of expert knowledge. Because, even if there are stringent guidelines for almost all use cases, no experiment is exactly the same as another.?

Applications of environmental simulation

Depending on the specified requirements, environmental simulations cover a wide range of test scenarios and parameters. They are generally used to study the affects of a wide range of environmental factors on?

• performance,
• function,
• long-term behavior,
• service life, and
• the reactions to the environment of a test object or a living system.?

Particularly in the field of electronics, but also in other industries such as automotive, aerospace, and medical research, dynamic climate chambers have proved to be successful in environmental simulation. We have used concrete applications in our?Case Studies on the dynamic climate chamber.

Environmental simulation: Hardware and expertise from BINDER

Dynamic climate chambers meet a wide range of requirements within their specifications that are relevant when simulating real environmental conditions. These include:?

• temperature control
• humidity control
• cyclical programming?

To set additional parameters,?good dynamic climate chambers?can be customized and upgraded for the specific requirements.

Standardized testing procedures

Environmental testing procedures are always subject to customized requirements specifications. The general guidelines for categorizing environmental simulations is regulated by the first part of the IEC 60068 standard. The following sections look at the specific requirements of the respective applications.?

All the named testing procedures are used to establish the resistance of the test object to environmental factors:?

• in transit
• in storage
• during installation
• under actual operational conditions above the expected service life?

Economic considerations also play an important role in determining the standardized test conditions. Specifying an adequate testing period helps to save costs. By contrast, more comprehensive test series mostly pay off in the form of improved product quality and increased reliability.?

When creating standardized testing conditions for environmental simulation, do not hesitate to draw on external expert knowledge. BINDER has many years of experience in this field and not only offers the required measuring technology but also in-depth knowledge on how to use it.

Standardized test results are absolutely essential when it comes to testing materials. This applies even more to challenging use cases, such as long-term measurements, or under constantly changing conditions.
