The test chamber is pressurized and supplied with moisturized, heated air to obtain the desired climatic condition, the climatic condition being maintained by surrounding the test chamber with an insulated housing. A double door arrangement is provided to effect a pressure seal and for isolation of the test chamber from any appreciable heat loss.
