PURPOSE: A chamber for testing the emission of contaminants of vehicle-embedded parts and construction materials is provided to measure an accurate amount of the contaminants generated in the vehicle-embedded parts and building construction materials by improving sealing-ability and the even distribution of air inside the chamber. CONSTITUTION: A chamber(100) for testing the emission of contaminants of vehicle-embedded parts and construction materials comprises a test chamber(10), an inner circulation blade(60), a magnetic stirrer(40), an air supplying connection port(12), a buffer bag connection port, and an air sampling port(21). A packing member(31) is installed between an inner cover(20) and a pushing cover(30) so that testing chamber is sealed by pushing the pushing cover. The inner circulation blade can makes the inner temperature and the internal air of the testing chamber uniform. The magnetic stirrer has thermal stability capable of driving the inner circulation blade. The air supplying connection port supplies external air. The buffer bag connection port maintains the inner pressure of the testing chamber regularly. The air sampling port collects the air of the testing chamber.
