Abstract: In modern life, indoor environment is the place where people have the longest contact time and the closest influence. To ensure the living environment health and comfort, people usually choose environmentally friendly indoor decoration, furniture, etc., or use air purifiers, humidifiers, range hoods and other electrical products to enhance the indoor air quality. Test chamber is a pivotal equipment for the evaluation and testing of building materials, interiors, air purifiers, air conditioners, range hoods and other products. It can well simulate the indoor environment during the test and provide a closed experimental space for testing the release or purification capacity of harmful substances of relevant products. Take a test chamber project from design and construction to final acceptance as an example, to introduce how the laboratory designs the specification, function and safety protection of the test chambers according to the actual requirements. Then carries out the acceptance of the test chamber through a series of processes such as calibration, safety confirmation and comparison test, until they could finally put into use. Aims to provide reference for industrial application.
