or 3/8 in. Based on a compendium of fire tests, the fire resistance rating of reinforced concrete masonry columns is based on the least plan dimension of the column as indicated in Table 4. This could include descriptions such as Fire Door Frame, Transom or Sidelight Panel, Fire Window Frame (3/4 Hr., 1 Hr. It also acts as a heat sink, reducing the chance of fire on unexposed sides of the assembly. For finishes on the fire-exposed side of the wall, a time (from Table 8) is assigned to the finish. Allowable Stress Design of Concrete Masonry Lintels. The manufacturers certification information in the UL Product iQ database also describes the components used in the assembly. Model codes include requirements for doors which serve the means of egress system, which are referred to as exit (egress) doors. Fire and smoke protection Building codes rely on fire and smoke protection features to safeguard the public and emergency responders from fire and smoke hazards. UL FIRE RESISTIVE ASSEMBLIES Fire Ratings specied in this section pertain to UL Classications which are based on standard test method ANSI/UL263, ASTM E11 9, UBC 7-1, NFPA 251, CAN/ULC - S101M . 1. UL W461. Gypsum board and fire caulk with non-rated roof. Through Penetration Products for Firestopping | 3M 722.6.2.1 Fire-resistance rating of wood frame assemblies. Openings in the roof shall not be located within 4 feet (1220 mm) of the fire wall. Click the link above, each design number below represents a James Hardie 1 hour Fire Resistive Wall Assembly. The fire resistance rating of multi-wythe walls (Figure 2) is based on the fire resistance of each wythe and the air space between each wythe using the following equation: R = (R10.59 + R20.59 + + Rn0.59 + A1 + A2 + An)1.7. UL Solutions structures this activity to be distinct and separate from its conformity assessment bodies. Your Complete Guide to LP FlameBlock Flame-Resistant Assemblies National Gypsum pioneered the development of fire-rated horizontal membranes with UL design G586 . UL Fire Classifications for Roofs - Class A, B, and C - Carlisle SynTec 9), or vermiculite complying with C516,Standard Specification for Vermiculite Loose Fill Thermal Insulation(ref. Start saving documents for quick referenc or log in to view previous folders. UL D798. 2. Code authorities should be consulted as to whether the assembly is acceptable for a specific location. U.L. listing for one hour wall (Stucco and 5/8" type 'x' gyp) While test methods such as ASTM E119 define procedures for evaluating the fire resistance properties of concrete masonry assemblies, including those constructed using unconventional constituent materials, there has historically been no defined procedure for applying the results of ASTM E119 testing to standardized calculation procedures available through ACI/TMS 216.1. Figure 3 shows control joint details in fire-rated wall assemblies in which openings are not permitted or where openings are required to be protected. Hardware includes locks, latches, hinges, electric strikes, flush and surface bolts, viewers and fire exit hardware. UL Designs & Thickness Floor Assemblies | GCP Applied Technologies Extensive testing has established a relationship between fire resistance and the equivalent solid thickness of concrete masonry walls, as shown in Table 1. Assembly rating:2 Hour; Gypsum wall to concrete or hollow core floor (with max. Door sizes Door sizes are sometimes dictated by code requirements. The basic standard used to investigate special locking arrangements is the UL 294 Standard for Access Control System Units. Connect with us in person or online, around the globe. Finishes that contribute to the total fire resistance rating of a wall must meet certain minimum installation requirements. The IBC and ACI/TMS 216.1 make provision for calculating the additional fire resistance provided by these finishes. There are also requirements in place for special locking arrangements that allow for egress while also providing a suitable level of security for the premises. The installation instructions include the type(s) and size(s) of glazing materials permitted, and the accessories or hardware permitted that are not Classified separately. . 6), that are commonly available include 100% solid units, 75% solid units, and hollow units meeting minimum required face shell and web dimensions. In addition to these prescriptive fire resistance rated control joints, other control joints may be permitted in fire rated masonry walls. Select appropriate hardware In order to operate properly, door hardware needs to be outfitted on the door assemblies. Fire-protection ratings Fire doors include a rating of 4, 3, 1-1/2, 1, and hours, or 30 or 20 minutes, which indicates the duration of exposure to fire. The window frame prepared at the factory for the glazing material does not always include the glazing material. UL Wall Assemblies with STC and Fire Ratings - Knauf Insulation North Oversized doors Freight elevator type, rolling steel type, and sliding or swinging steel-covered composite type, hollow-metal type, metal-clad (Kalamein) type, sheet-metal type and tin-clad type are fire tested up to the sizes recorded in the listings published under their respective product categories.
