What Is Environmental Test Chamber?

Before understanding the environmental test chamber, let's first understand "environment" and "test chamber". "Environment" consists of many environmental conditions, which refers to the sum of external conditions experienced by the sample to be tested in a specific time, which can be mechanical, climatic , biological, and other effects due to chemically and mechanically active substances. The definition of "test chamber" is "a certain part of an enclosure or space capable of achieving specified test conditions" to simulate the environmental factor parameters required to be tested and their corresponding severity. "Environmental testing" demonstrates that the sample to be tested is intact and functioning properly under specified conditions by simulating real (natural) environmental conditions or by reproducing their effects.

In layman's terms, an environmental test chamber means that the laboratory environment is not a conventional atmospheric environment, or the environment does not meet the environmental conditions required for sample inspection, and it is necessary to manually build or simulate a closed space that meets the test environmental conditions for testing. . Laboratory testing generally uses an environmental test chamber to simulate the environmental conditions required for various tests.

One of the most important test items is the climate test, and the test links such as high temperature, low temperature, high humidity, low humidity, illumination, and even alternating humidity and heat cycle are carried out at the same time or in sequence, so the environmental test chamber is also called artificial climate chamber, environmental test chamber. , constant temperature and humidity test chamber, high temperature and high humidity chamber, high and low temperature alternating chamber, etc. The main fields involved include reliability testing of electronic components, stability investigation of chemical and new energy materials, design and manufacturing of automobiles and spare parts, semiconductor wafer production and packaging, and stability related to drugs (chemical, traditional Chinese medicine and biopharmaceuticals). Research, cosmetic and food microbiological testing, and third-party testing.

In addition, in different application fields and standard adaptation ranges, environmental test chambers have different names. In the field of life testing and reliability inspection, it will be called an aging chamber; in the pharmaceutical industry, it will be called a stability test chamber or a light incubator; in the field of agriculture and animal husbandry, it will be called a light incubator or a plant cultivation growth chamber; When it is resistant to special environmental conditions such as high temperature and high humidity, it may also be necessary to investigate the degree of bacteria growth and the impact of bacteria growth on the performance of the equipment. At this time, it may be called a bacteria growth test chamber.
