Type 1: Fire-resistive: High-rise buildings made of concrete and protected steel. Of the three ratings mentioned above, the Fire-Resistance Rating (FRR) is the most frequently referenced. According to the Engineered Wood Association, a one-hour rating indicates that a wall constructed in a manner similar to the one tested will contain flames and high temperatures, and support its full load, for at least one hour after the fire begins. Interior walls and partitions of nonsymmetrical construction shall be tested with both faces exposed to the furnace, and the assigned fire-resistance rating shall be the shortest duration obtained from the two tests conducted in compliance with ASTM E119 or UL 263. Some walls might appear to be demising walls, but they are only separation walls. This is achieved by mandating that critical building components meet minimum fire ratings.
