TEST CHAMBER FOR EMITTING POLLUTANTS WITH AIR SUPPLY PIPE

摘要

The present invention relates to a pollutant emission test chamber with the air line. The invention cap unit 210 in the air discharge channel 217 is provided for discharging the air in the air supply channel 213 and the test chamber for supplying air into the test chamber to the outside; Air line is communicated to vertically downward to one end of the air supply channel 213 supplies air into the test chamber 215; And at least one end by the shape of the open tube shape, an open end provided with a main body portion 230 is installed such that seal with the lid 210, and air line 215 and the sample 260, with the separation distance and air by the flow control of the air supplied from the supply tube 215 provides a chamber in which pollutant emissions test air is to control the flow area that the flow at the surface of the sample 260. ; Test chambers, pollution, building materials, air supply
