Abstract
Nine commonly used room finishing materials were subjected to the heat release and ignition tests under development at NBS and to the NBS smoke density test. Each material was tested with three different moisture contents representing 50 percent relative humidity (RH), 0 percent RH, and one intermediate RH value. The purpose of the tests was to gain experience with the test methods under development in order to determine whether instrumental or procedural modifications are needed an to examine the problem of testing a material at 50 percent RH and using it under much lower humidity conditions.
