Environmental testing is a prominent part of product development. The varying types of heat, cold, humidity, and dust are only some of the things that can damage a product. This is part of the reason why manufacturing industries and testing laboratories depend on an important piece of technology: environmental chambers.
With the Different Types Of Environmental Chambers, manufacturing industries can replicate different environments. This allows them to see the ways different materials and devices will perform. When developing medical devices, testing industrial components, or doing electronics testing, the chambers can help engineers make the product as safe as possible and ensure that the product will be reliable for years to come.
The purpose of this article is to show why environmental testing is a vital part of product development and what types of environmental chambers can be used.
Weather is unpredictable and has real consequences. Testing products can often take years to show the strain of constant exposure to the heat, moisture, and freezing temperatures that will be added to the product. This is known as the product's time-to-market. Using an environmental testing chamber can drastically alter this time-to-market by focusing on these damaging factors.
Many different industries, including electronics, automotive, and pharmaceuticals are using these chambers to test products prior to their release. Environmental testing is even a necessity for companies to make sure they comply with global standards (ISO, IEC).
I would like to point out that OTS Technik Environmental test chambers are known throughout the industry for their consistent testing solutions. Their chambers support numerous testing needs, assisting laboratories in achieving reliable outcomes in controlled settings.
A sealed testing unit with controllable temperature and humidity is called an environmental chamber. Other factors like air pressure, vibrations, and corrosive elements can also be controlled. aThe chamber is equipped with different sensors, a heating and cooling system, and programmable controls.
Most Environmental Chambers are equipped with all digital components. Users run the system through a detailed testing cycle.
This process is important because it signals to manufacturers a product's limitations, and, more importantly, preemptively saves their customers from unnecessary product failures.
Environmental chambers can be used in a number of different situations. The following are a few examples.
- Testing overheating issues in electronic circuit boards.
- Testing extreme temperature battery performance.
- Packaging the evaluation of humidity and moisture.
- Components of aircraft tested in simulated high altitude.
- The expansion of rubber, plastic, and metal in heat is also tested.
Environmental chambers are important and support the development of products in addition to the assurance of quality. They also reduce the repair costs and warranty cases that a company is likely to have.
Various types of environmental chambers are available, and each type of environmental chamber has its own use. The type of chamber needed depends on the product type, industry standards, and testing environment needed.
Given below are the major types of environmental chambers used across the globe.
After humidity chambers, Temperature chambers are arguably the most popular environmental testing chambers available. The chambers test the behavioral responses of most products at extreme high and low temperatures.
These chambers are used for testing electronically company products as well as plastic, automotive parts, and mechanical parts. Chambers can conduct tests as basic as holding a product at 80 degrees celsius for a few hours or advance cycling tests, meaning the temperature can shift from high to low continuously.
They can perform tests to identify:
- Cracking
- Expansion
- Internal Failure
- Melting
- Collapse
These chambers are fitted with:
- A heating and cooling system
- Programmable Control Panels
- Sensor for Control of accurate temperature
- a system for Uniform Airflow
These chambers can create damp, rainy, and tropical environments. Humidity Chambers test products that are exposed to a range of moisture levels that are purposely manipulated. These chambers can simulate tropical climates, rainy environments, and long-term damp conditions.
These chambers are important for testing:
- Electronic equipment
- Medical devices
- Food packaging
- Coated metals
- Textile materials
There are several important issues that stem from humidity: corrosion, mold, rust, and electrical shorts. Before products are released, humidity chambers allow companies to identify these issues.
Some chambers are even more useful because they combine both temperature and humidity.
A temperature and humidity combined chamber is a popular choice because it offers two testing conditions in a single system. It can mimic real world scenarios such as hot and humid or cold and damp environments.
This type of chamber is frequently used for:
- Consumer electronics
- Automotive sensors
- Industrial machinery components
- Communication devices
Advanced test cycles are made possible by combined chambers. For instance, a product can be tested for 48 hours at 40°C and 90% humidity and then rapidly cooled.
This type of test is useful for evaluating the quality of seals, the resistance of materials, and the stability of electronics.
These chambers test the extremes of temperature. Instead of slowly heating up or cooling down, the chambers rapidly change temperatures, moving products from one extreme to the next.
For example, products can be tested at temperatures ranging from -40° C to +150° C in just a few minutes. This testing assesses whether a product can withstand drastic changes in environmental conditions.
These thermal shock products are widely applicable and used in testing:
- Aviation and aerospace
- Military tech
- Electronic chips
- Automotive engine components
Thermal shock tests can uncover hidden defects like micro cracks, seal gaps, or bad solder joints.
Altitude chambers replicate the low-pressure conditions experienced at high altitudes. They are critical in the development of aerospace products and any equipment used within or near mountainous terrain.
Altitude chambers are used to test:
- Components of aircraft
- Navigation systems
- Parts of satellites
- Air transport medical devices
To simulate the high-altitude conditions, these chambers drop the air pressure within the chamber. This allows engineers to evaluate the performance, sealing, and stability and loss of pressure in the system being tested.
Salt spray chambers can be used to test for the potential of corrosion. The sprayers create a fog of salt which is used to accelerate the rate of formation of rust.
Salt spray testing is important for:
- Parts of car bodies
- Equipment for the ocean
- Coatings for metal
- Industrial nuts and bolts
- Materials for finishing and painting services
Manufacturers can use this to test the quality of their coatings and the level of corrosion protection. It is used for a lot of services that require that the equipment stand the test of time and endure being used outdoors and used often.
Salt spray testing is part of the international protocols for testing, such as ASTM B117.
Chambers that are meant to be walked into are used to test equipment that is large or to test many products at the same time. These large chambers have the ability for a person to walk into them and adjust the testing apparatus.
Walk-in chambers are often used for:
- Engines for automobiles
- Big systems of electronics
- Testing of storage products in bulk
- Assemblies for aerospace
- Machinery for the military
These chambers provide a lot of adaptability. They allow the testing of large samples and to perform multiple test cycles without being limited by space.
Chambers of Vibration provide a combination of environmental stress with the addition of physical vibration. This is used to simulate conditions that can be experienced during transport or operational use.
Simultaneous heat and vibration stresses are scenarios where a product may have to function. This test is useful to prepare a product to face multiple real-world stresses.
Vibration chambers are used for:
- Components of vehicles
- Systems of aerospace
- Machinery that is heavy
- Electronics that are shipped over long distances
These chambers can identify and help fix issues such as loose connections, mechanical issues, and poorly designed assemblies.
Dust and sand chambers replicate dry and dusty environments (e.g., deserts and dusty industrial zones). A dry and dusty environment can test products for and help to assess the performance with respect to the intrusion of dust.
Dust testing is standard for:
- Systems that provide outdoor lighting
- Enclosures that have electrical components
- smart devices and mobile phones
- air filters in vehicles
- Industrial switches
This is a protection for products that are designed for outdoor or construction use.
Rain test chambers simulate exposure to rain, that includes water from splashing, and water from high pressure. Because of the quality of the seals that are involved in the design of the products that are being tested, that is what the chambers are used for.
Rain chambers are commonly applied to:
- headlamps for cars
- electronics for the outdoors
- equipment that is waterproof
- solar panels
- boxes that are industrially controlled
Testing like this supports the IP rating verification, which includes standards like IP65 or IP67 for waterproofing.
Picking the right environmental chamber depends on the product and the goal of the testing. Each company must consider a few key factors:
- The range of testing temperatures
- Control of humidity
- Sample size versus the volume of the chamber
- Relevant industry testing standards
- Requirements of accuracy and stability
- Anticipated usage and maintenance frequency
Some products require simple heat testing, while others require complex stress simulations, such as vibration and humidity testing.
Selecting a chamber supplier that offers technical support and reliability is also crucial.
Environmental Chambers are uniformly utilized across a plethora of industries. These include, but are not limited to:
- Electronics manufacturing
- Automotive and transportation
- Aerospace and defense
