What is an Environmental Test Chamber and How Does It Work?

With the rapid development of modern industrial technology, electrical, electronic products have been widely used. At the same time, the environmental conditions are becoming more and more complicated. Only by properly regulating the environmental protection measures of the products can the products be protected from damage during storage and transportation, and safe and reliable during use. Therefore, electrical and electronic products used in artificially simulated environmental tests are an essential part of ensuring high quality.

In this article, we’ll explain what a test chamber is and how does an environmental chamber works.

What is Environmental Test Chamber?

Before we learning the environmental test chambers, we should know what the Environmental Test is, and where it can be used. This test is not difficult, the principle of it is widely used in our daily life, like refrigerator, which can change temperature to help food keep away from the deterioration.

Every product made from industry will suffer from the damage of environment. The Environmental Test can help you to find the point which the product will be damaged at. For measuring the availability of your products the Environmental Test Chambers accelerate the changing of environment, or add extreme conditions that the natural absolutely can not reach.

Therefore, with the help of the Environmental Test Chamber you can know the information about how long your products can be used in nature environment, and the peak which your products can reach in an extreme environment will be find.

Some conditions that the Environmental Test Chamber can take for you:

1.Temperature variations: With temperature variations, you can find the thermal section that your products can bear.

2.Humidity: As one of the most effective factors in environment, humidity bothers products all the time. With the Environmental Test Chamber, we can easily change the humidity for your products bearing.

3.Salt spray: Also called salt fog test, salt spray test is one of the most popular corrosion test methods.

4.UV degradation: Many of products are always exposed to the sun, so it is necessary for your products to have a UV degradation test which can help you to find the bearing section of that.

5.Vacuum: The vacuum condition for some special products.

6.Stimulate weather: For some products that are mainly effected by weather factors .

Most Environmental Test Chambers can change the conditions we have listed, according to that, we can classified the Chambers.

The representative test chambers include:

Thermal shock test chamber
salt spray test chamber
ultraviolet aging test chamber
xenon lamp aging test chamber
ozone aging test chamber

High and low temperature test chamber
Constant temperature and humidity test chamber
Temperature humidity vibration combined test chamber

The Environmental Test Chamber is always used in these test:

We utilize different test chambers for different intentions, for environmental tests, there are four main tests that the chamber usually be used.

Steady State Tests: The chamber controls the temperature and humidity may other factors in a certain scope and hold the temperature in a certain time. You can use this type of tests to measure the service life of your products, or to test the stability in a certain environment for long time. The result of this test will be more accurate.

Thermal Cycling Tests: In this test, the chamber provides two extreme environments for your products, and shift between them in a period of time. It is a slow process. During this test, the variation of your products should be visible.

Thermal Shock Tests: This test just like its name, the chamber takes an extreme environment for your products quickly. Then you will find the peak bearing of them to against the extreme environment.

Slat Spray Test: Also called salt fog test, it is widely known as one of the corrosion test. Using this test you can find the availability of your products when they are exposed to the real environment.

The thermal cycling tests are similar with the thermal shock tests, but they are very different things. Thermal cycling test is a slower process than thermal shock test. Though both of them provide two environments for products, but thermal cycling test is a slower test than thermal shock test. With controlling certain temperature and humidity, thermal cycling test would take an accurate result for manufacturers. On the other hand, the thermal shock test will take data about the durability that your products in a switching two extreme environments.

The size of Environmental Test Chamber: Ranging from the Walk-in or Drive-in Chamber to the small size chamber that can put on a placement like big desk or somewhere like that.

How Does an Environmental Chamber Work

The temperature and humidity test chamber is suitable for testing electronic, electrical appliances, food, automobiles, rubber, plastic glue, metal and other products. It can meet different environmental conditions such as high temperature and high humidity, high temperature and low humidity, low temperature and high humidity, high temperature and low temperature, and will provide you with the basis for forecasting and improving product quality and reliability.

They mainly use temperature and refrigeration systems. The main function is cooling, generally using advanced refrigerator control technology to stabilize the test space. Secondly, the test chamber also needs to use the dehumidification system to solve the problem of humidity.

(1) High low temperature test chambers are suitable for high temperature and low temperature reliability tests of industrial products. For the parts and materials of related products such as electric and electronic, automobile and motorcycle, aerospace, shipbuilding, colleges and universities, research institutes, and other high-temperature and low-temperature (alternating) cyclical changes, test their performance indicators.

(2)The constant temperature humidity test chamber is also called constant temperature humidity test machine. It is used to test various materials for heat resistance, cold resistance, dry resistance and moisture resistance. It is suitable for electronics, electrical appliances, communication, Instruments, vehicles, plastic products, metals, food, chemicals, building materials.

(3)The salt spray corrosion test chamber can evaluate the salt spray corrosion resistance of the material and its protective layer, and the process quality of similar protective layers. At the same time, it can evaluate the resistance of some products to salt spray corrosion. The product is suitable for parts and electronics. Original, protective coatings for metallic materials and salt spray corrosion tests for industrial products.

(4)The thermal shock test chamber usually uses two extreme environments, puts the product in and shift the two environments quickly. With this test, the resistance to switching between extreme environments that products have is visible.

Why You Need Environmental Test Chambers?

Industrial products are subject to various temperature, humidity, climate and external conditions during manufacturing, handling, storage and application. These factors may cause physical, mechanical, and even chemical changes in the product. This will make the product lose its effect, reduce the value or create danger!

Had you heard a explosion of a cell phone? Or met a situation that a product can not work even when you utilize it at first time? All these problems were caused by the lack of the quality of your products. So it is important that make a test to measure the durability of your products!

Environmental Test Chambers simulate common or external environments for your products to measure their durability. With ECT Chambers you can change the temperature or humidity,even create the climate you want, and find the problems that hide in glamorous surface of your product.

Find them! And solve them! Your products will become more prefect!

On the other hand, with Environmental Test Chambers, the data you got from the test is valuable for your research & development.

There are some reasons why you need Environmental Test Chambers:

There are different climate between your aim markets and producing area: Different areas have different climate that made by different temperature and humidity. Your products may have a well resistance of dry, but difficult exist in wet weather. Thinking of that, you need an Environmental Test Chamber for your products.
With good quality your products are more reliable than your competitors: With Environmental Test Chambers, you can measure your products once and once again, find the problem and solve it, which can promote the quality of your products.
Promote the safety of your products: Customers prefer durable, crushing-resistant products, the former can make the product more valuable, but the last come from a safety considering.

Some products must be test before putting them into markets.

As we all known, a car without weather tests can not be sold. The weather test can help manufacturers find somewhere that the part of cars not assembled well. With many times of weather testing, finally promote the safety of the car. Only pass this test, the product can be sold.
