With the improvement of people’s life quality, the products used quality are improving. In the environmental testing of products, the environmental factors become more complex. And the corresponding environmental testing projects are becoming more and more many. The requirements for product reliability are also becoming more and more stringent. Environmental test chambers are becoming more and more diversified.
Introduction of the environmental test chamber
The environmental test chamber establishes or simulates closed space by testing environmental conditions. Laboratory tests are generally used to simulate the various environmental conditions required. Climate testing is a very important test item. An environmental test chamber is known as an artificial climate chamber, etc.
It involves the field of electronic components reliability testing, chemical, third-party testing, etc.
The classification of the environmental test chambers
Environmental test chambers can simulate various chemical, physical, biological, and other environmental factors. It uses to test the performance and reliability of products in different environments. There are many types of environmental testing instruments. These are some common environmental test equipment.
Two-chamber Cold And Hot Shock Test Chamber:
It is widely used in many fields . Such as aerospace, household appliances, etc… It can assess the performance changes of materials after high and low-temperature tests. Automotive appliances, electronics, and other materials can place inside to test the performance. It can do the safety performance test of electronic components. Moreover, it can provide reliability tests, product screening tests, etc… Equipment testing improves the product’s reliability and carries out the product’s quality control.
Constant Temperature And Humidity Test Chamber:
It simulates a constant temperature and humidity environment. It usually controls temperature and humidity between 5%-98%RH and -40°C-150°C.
It can test the material’s performance in different environments. For example, it can test the dry/moisture resistance of different products. At once, it also tests the heat/cold resistance. For example, testing electronic products under different temperature and humidity conditions. The same can do in high and low-temperature environment storage and transportation tests.
High And Low-temperature Test Chambers:
The environment test chambers can simulate high and low-temperature environments. Usually, the temperature can control between -70 ℃ -150 ℃. Suitable for industrial products of high temperature, low-temperature reliability test. It can be automobiles in high temperatures, the low temperature under the cycle of change. And its performance indicators test.
Oven:
The oven is drying equipment, which can see in the drying process. It uses electric heating to raise the temperature so about achieve the drying effect. Of course, it uses more in metal processing and food drying. It uses on occasions where the requirements for drying speed are not high.
Salt Spray Test Chamber:
It is also called a salt spray corrosion test chamber. It assesses the salt spray corrosion capacity of materials and protective layers. It can do the salt spray corrosion test of industrial products.
Xenon Lamp Aging Test Chamber:
Xenon lamp aging tester, also known as “sunlight radiation protection test device”. It generates destructive light waves by simulating the sunlight spectrum. Meanwhile, it provides corresponding environmental simulation and acceleration tests for quality control. It can do tests for durability changes in materials. For example, this test selects of new materials or evaluation of material composition. It can simulate different environmental conditions and the change of materials under sunlight. Additionally, it divides into three types air-cooled, water-cooled, and bench-top xenon lamps. The difference lies in the test temperature, humidity, accuracy, time, etc.
Ozone Aging Test Chamber:
It can do the aging cracking test. Rubber products and non-metallic materials are able to do this test. Which divides into two experimental methods: static stretching and dynamic stretching. Exposure to a temperature test chamber with constant ozone concentration under static stretching. Evaluate ozone resistance of products by the crack’s appearance or other property changes.
Two-chamber Cold And Hot Shock Test Chamber:
It is widely used in many fields . Such as aerospace, household appliances, etc… It can assess the performance changes of materials after high and low-temperature tests. Automotive appliances, electronics, and other materials can place inside to test the performance. It can do the safety performance test of electronic components. Moreover, it can provide reliability tests, product screening tests, etc… Equipment testing improves the product’s reliability and carries out the product’s quality control.
Two-Chamber Cold And Hot Shock Test Chamber
Temperature Shock Test Chamber-Three Zone:
It uses to simulate various shock environments. Likewise,It can evaluate the ability of the product to withstand instantaneous shock. Testing equipment for metal, plastic, and other material industries is necessary.
It used to test the material structure or composite materials. It can detect physical or chemical damage caused by thermal expansion and contraction.
High And Low Temperature Alternating Hot And Humid Test Chamber:
It can provide high and low temperatures or hot and humid environments. It uses to test the performance index of electricians, and various electronic components.
Air-exchange Aging Test Chamber:
For electrical insulation materials, it can do a heat resistance test.
And for electronic parts and plasticized products, it can do the air exchange aging test.
Sand And Dust Test Chamber:
It can do dustproof and dust resistance tests on various auto parts.
It can test door locks, electrical dust covers, lamps, etc.
UV Aging Test Chamber:
It can do both non-metallic material sunlight resistance test. It can also do the aging test of artificial light source. It uses UV light to simulate solar radiation to test the properties of materials. Such as stretching, fading, and cracking.
It uses fluorescent UV lamps to speed up the weathering test. It obtains results by performing accelerated weathering tests. It can simulate rain, and high temperatures, and combine them by reproducing them.
Box-type Rain Test Box:
Besides,test the performance of automotive lamps, and wipers. It can also test the waterproof performance of low-voltage electrical housing protection.
Rapid Temperature Change Test Chamber:
It can simulate a rapid temperature change environment. And it can evaluate a product’s performance and reliability in fast temperature changes. According to the temperature rise and falls in a linear and non-linear way.
Vibration Test Bench:
It can simulate various vibration environments. Such as earthquakes, vehicle movement, machine vibration, etc… To identify the vibration tolerance of the product.
Summary
As the application continues to deepen, more types of environmental test chambers. Meanwhile, the environmental test chamber application scope is also more subdivided. It can meet the needs of work in different environments. So when purchasing an environmental test chamber, according to specific role and environment.
In short, environmental testing equipment is an important means of testing. It helps companies to assess products’ performance and reliability in many complex environments. It also helps companies to improve their goods mass and their markets competitiveness.
