The process of the test of pollutant release with the environmental chamber can be summarized as: putting materials and products or their samples in the test chamber, and adjusting environmental conditions such as temperature in the chamber, relative humidity and air exchange rate; sampling at the exhaust port or the inside of the environmental chamber; adopting appropriate methods to analyze gas samples and identify major pollutants and the changes in their concentration with the time; then confirm the release rate and release properties of materials and products according to the measured concentration.
