What is an environmental test chamber
- Mar 21, 2018 -

An environmental chamber, also called a climatic chamber or climate chamber.

A test chamber is a specially manufactured controlled environment that companies use to check the 

endurance or stability of equipment, products, and substances. Environmental test chambers simulate the 

climactic conditions that products are most likely to encounter during use.

These conditions may include:

extreme temperatures

sudden and extreme temperature variations - thermal shock


moisture or relative humidity

electrodynamic vibrations

electromagnetic radiation

Cyclic corrosion testing

salt spray



exposure to sun, causing UV degradation


Manufacturers design and construct test chambers in a number of sizes ranging from 2 cubic feet (0.05 

cubic meters) of space to entire room-sized chambers. Most contain stainless steel interiors, and some are 

equipped with internal lighting and viewing windows.
