What is Enviromental Test Chamber?
An environmental test chamber artificially replicates the conditions under which machinery, materials, devices or components might be exposed. It is also used to accelerate the effects of exposure to the environment, sometimes at conditions not actually expected.
These conditions may include:
· extreme temperatures
· sudden and extreme temperature variations
· moisture or relative humidity
· electro-dynamic vibrations
· electromagnetic radiation
· salt spray
· exposure to sun, causing UV degradation
Manufactured samples, specimens, or components are placed inside the chamber and subjected to one or more of these environmental parameters to determine reliability or measure after-effects such as corrosion. In the case of machinery such as internal combustion engines, byproducts such as emissions are monitored.
An environmental chamber can be a small room used both to condition test specimens and to conduct the test. It can be a smaller unit that's used for conditioning test items. Also, some chambers are small enough to be placed onto a universal testing machine or other test apparatus.
Many chambers are set at a certain set of conditions. Others can be programmed to cycle through specified sequences of conditions.
Test equipments are various, such as paper packaging test equipment, furniture test equipment and so on.
