Rugged electronics environmental testing methods you need to know

Environmental testing labs near me have been applied and used in different fields. Today we are going to look at the test procedures and set of methods that have governed considerations for defense applications and aerospace for over sixty years in the environmental engineering field.

 

Considerations for environmental engineering and lab tests

There are different types of environmental tests used for ground equipment and aerospace in areas such as vibration, temperature and immersion. There are different test methods used in this area and that is what we will discuss in this article.

 

Low pressure

This is a common and popular method that determines whether different materials can safely and successfully withstand rapid pressure and low-pressure changes. These environmental tests apply to products stored or used in unpressurized and pressurized areas of an aircraft. Fast pressure changes are usually simulated in rapid decompression and explosive decompression. These two main procedures focus on the safety of the crew to ensure the effects of a catastrophic airborne event aren’t worsened by equipment on board and endanger people.

 

High temperature

Climatic conditions are usually used to define ranges for induced and ambient temperatures that materials are tested against and these design types like hot dry mimic the climate experiences all over the world. In this method, the short-term safety, performance and integrity of a product are examined against hot dry and basic hot climatic design types that range from 30 to 71 degrees Celsius.

 

Low temperature

Environmental testing labs can also use low temperature just like the high-temperature method to evaluate the ability of a material to withstand certain climatic conditions. Storage, operational and manipulation tests range between 21 and 51 degrees Celsius depending on the environment of deployment.

 

Temperature shock

This is another popular method that examines the impact of the performance of a product and its integrity when the product is subjected to temperature changes of more than 10 degrees Celsius. The sudden air temperature changes can represent a component moving from an area that is climate-controlled to extreme ambient conditions and induced at a rate of about 3 degrees Celsius per minute.

 

Contamination by fluids

With this method, a material is usually exposed to contamination fluid to determine whether or not the exposure will fail. The list of test fluids includes antifreeze, diesel fuel, and more. Careful attention should be given during the design of the product to ensure all non-metallic and porous parts are well-protected against these possible contaminants.

 

Solar radiation

This method evaluates the impact of solar radiation’s heating effects on a product. It also identifies the actinic effects of the exposure which can present in the loss of fading of paint, seal integrity and failure of the electronic components.

 

Rain

This method can be used by environmental testing labs near me to test the ability of a material to withstand rain without being damaged as a result of leaking covers, cases or seals. There are three procedures test conditions with specified volume, speeds and drip patterns used.
