Before the development of fire-rated horizontal membranes, architects used UL fire-rated wall assemblies turned horizontally, or shaftwall systems for corridor ceilings. The Mark typically describes if the frame includes sidelights and/or transom panels, may include hourly ratings, and may describe if the frame was evaluated without hose stream. Doors with glass light panels meeting the size limitations and the rating requirements of the installation code carry the same rating as similar doors without glass light panels. Some manufacturers can provide labeled transom panel frames for use with doors rated up to and including 3 hours as indicated in the individual certifications. 30 MIN 250F MAX, 30 MIN 450F MAX, 30 MIN 650F MAX or No Reference Provided). The calculated fire resistancerating of steel columns protected by concrete masonry, as illustrated in Figure 5, is determined by: R = 0.401(Ast/ps)0.7 + [0.285(Tea1.6/kcm0.2)] x [1.0+42.7{(Ast/wcmTea)/(0.25p+Tea)}0.8] (English Units), R = 1.019(Ast/ps)0.7 + [1.413(Tea1.6/kcm0.2)] x [1.0+1736.41{(Ast/wcmTea)/(6.35p+2.54Tea)}0.8] (Metric Units). Looking for inspiration? Some manufacturers can provide labeled door frames with side panels or sidelights. Sound absorption characteristics, helping reduce noise transmission. Ability to provide thermal resistance for comfort and efficiency. Products bearing any of these UL marks comply with the definition of a listed product in the code, and should be considered to be listed. One aspect of this protection is based on limiting the movement of fire and smoke through the building using a compartmentation approach (also called the fire area). UL certifies products for use in these applications under the Leakage-rated Door Assemblies (OPBW) category. These products are investigated in accordance with UL 9, Standard for Fire Tests of Window Assemblies. Fire testing of a steel column protected by concrete masonry evaluates the structural integrity of the steel column under fire test conditions, by measuring the temperature rise of the steel.
