• Abstract:

  This paper gives the fire-resistance and sound-insulation ratings of walls, partitions, and floors. Most of the fire-resistance ratings are based on tests made at the National Bureau of Standards. Some are based on tests made at Underwriters’ Laboratories or at Ohio State University. All of the sound-insulating ratings are based on tests made at the National Bureau of Standards. The detailed results of many of the fire tests of wood- and metal-framed partitions have been published in Building Materials and Structures Report BMS71, “Fire Tests of Wood- and Metal-Framed Partitions.” The details of the sound-insulation tests are given in Building Materials and Structures Report BMS17, “Sound Insulation of Wall and Floor Constructions”, and Supplements 1 and 2.
