For finishes on the non-fire-exposed side of the wall, the finish is converted to an equivalent thickness of concrete masonry by multiplying the finish thickness by the factor given in Table 7. Standard Specification for Prefaced Concrete and Calcium Silicate Masonry Units, ASTM C744-16. Mullions, transom panels and other features Standard door frames are of the single-unit or three-section type and consist essentially of steel head and jamb members, including hardware reinforcements, wall anchors, door stops, and provisions for anchoring to the floor. Latch retraction options are factory supplied as part of the exit device or may be certified as an accessory for use with single-point locks or latches and fire exit hardware (GWVW) category. In multi-layer assemblies, do I have to fire-tape the base layer? Concrete masonry column fire testing evaluates the ability of the column to carry design loads under standard fire test conditions. F. FIRE DOOR AND WINDOW HARDWARE AND ACCESSORIES. While finishes are normally applied for architectural reasons, they can also provide additional fire resistance. See a complete list of UL rated interior wall and floor/ceiling assemblies that include both AFB and ROCKWOOL Safe'n'Sound. For partially grouted walls where the unfilled cells are left empty, the equivalent thickness for fire resistance rating purposes is equal to that of an ungrouted unit. Q. From Table 1: T1 for expanded shale (3 hr rating) = 4.4 in. 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. 8B. Some manufacturers have opted to mark their frames for conformity to positive pressure as noted below. Gypsum Board* Any 5/8 in. It combines flame-spread and burn-through resistance to give your customers peace of mind. veneer, non-load bearing exterior wall assembly. 2023 Louisiana-Pacific Corporation. The contract documents often contain just the Underwriters Laboratories, Inc. design number, such as UL U405 and nothing more. Source: Google. Only products bearing the UL Certified or Listed Fire Exit Hardware Label are rated for use on fire door assemblies and should not be confused with UL Certified Panic Hardware Label which is only intended for use on non-rated exit doors. UL offers a field evaluation service that provides a method to assist you in making your decision whether to accept the product and/or approve the installation. For more information on steel columns protected by concrete masonry, see TEK 7-6A, Steel Column Fire Protection (ref. The system also is somewhat inflexible in that little variation from the original tested wall assembly is allowed, including unit size, shape, mix design, constituent materials, and even the plant of manufacture. The actuating paddle is an arm, push plate or paddle which functions as the activating mechanism of an exit lock on the egress side of the door. Devices so Classified are covered under Hardware (GWGR). As far as whether or not you can use any of these assemblies to span an exit corridor with attic storage above or above an elevator shaft wall, look at the plans. These wall assembly files are used for planning and estimation purposes for many UL wall types, such as fire-rated wall assemblies. Similarly, a Certification Mark for Passenger Elevator Fire Door Frame Assemblies incorporating a transom panel can be provided when such frame/transom panel assemblies, designed for use with specific Classified Passenger Elevator Fire Doors and Listed Passenger Elevator Fire Door Hardware, exceed the maximum heights which have been subjected to Standard Fire Tests. Products not bearing a UL Mark are not considered to be UL Certified. From the standpoint of life safety (particularly for fire fighters) and reuse, this failure mode is certainly preferable to a structural collapse endpoint, characteristic of many other building materials.
