Using the UL Directory • Fire Resistance Directory • Alpha Numeric Numbering System • Different for Joints and Penetrations • Website is Most Current
UL ApprovedNo Such Thing (Only AHJ approves products/systems • UL ClassifiedLab has used the country requirements to evaluate the product for specific hazards or properties • UL Listed Passes the standard test and is in the lab’s directory
Company ABC – SuperDuper Sealant • What type of building assembly is requiring firestopping? • Floor or Wall • What type of material is the building assembly • Concrete, CMU, Gypsum, Wood Frame • What is the penetrating item(s)? • Metallic, Nonmetallic, Cables, Insulated, Construction Joints, etc. • What are the specific descriptions regarding the penetrants? • Diameter, quantity, type of plastic, type & thickness of insulation, etc. • What is the hourly rating you are looking for? • F Rating, T Rating • Are there any special considerations? • Movement, Environmental exposure
Navigating UL Example 1: UL Listed - Through Penetration System C-AJ-1079
Navigating UL: THROUGH PENETRATION FIRESTOP SYSTEMS (XHEZ) First Alpha Character– signifies what is being penetrated F = Floors W = Walls C = Walls and Floors C-AJ-1079 Combination – Floor or Wall
Navigating UL: THROUGH PENETRATION FIRESTOP SYSTEMS (XHEZ) Following Alpha Character(s)– wall or floor construction type A = Concrete floors 5 inch thick B = Concrete floors 5 inch thick C = Framed floors D = Steel decks in marine vessels E-I = Reserved for future use J = Concrete or masonry walls 8 inch thick K = Concrete or masonry walls 8 inch thick L = Framed walls M = Bulkheads in marine vessels N-Z = Reserved for future use C-AJ-1079 Construction Type of Floor or Wall
Navigating UL: THROUGH PENETRATION FIRESTOP SYSTEMS (XHEZ) Numeric Component– first digit identifies the type of penetrant, next three are sequential system numbering 0000-0999 = No Penetrant 1000-1999 = Metallic pipe, conduit or tubing 2000-2999 = Nonmetallic pipe, conduit or tubing 3000-3999 = Electrical cables 4000-4999 = Cable trays with electrical cables 5000-5999 = Insulated pipes 6000-6999 = Busways 7000-7999 = HVAC ducts 8000-8999 = Mixed multiple penetrations 9000-9999 = Reserved for future use C-AJ-1079 Penetrant Type C-AJ-1079 Individual System Number
What type of building assemblies is the joint formed by? • Floor/Floor, Floor/Wall, Wall/Wall, Top of Wall/Ceiling • What type of material is the building assembly • Concrete, CMU, Gypsum • What is the hourly rating you are looking for? • Assembly rating (1 – 4 hour) • How big of a joint is required (inches) • How much movement is required? • Must accommodate building movement (% of joint size) • Are there any special considerations? • Unique construction condition, environmental exposure
Navigating UL Example 2: UL System - Joints HW-D-0034
Navigating UL: JOINT SYSTEMS (XHBN) First Two Alpha Characters– identify the type of joint system FF = Floor-to-Floor WW = Wall-to-Wall FW = Floor-to-Wall HW = Head-of-Wall HW-D-0034 Barriers That Form The Joint
Navigating UL: JOINT SYSTEMS (XHBN) Next Alpha Character– identifies the movement capabilities of the system D = Dynamic (movement capabilities) S = Static (no movement capabilities) HW-D-0034 Movement: Static or Dynamic?
Navigating UL: JOINT SYSTEMS (XHBN) Numeric Component– first digit identifies the width of the joint system, next three are sequential system numbering 0000-0999 = joint 2 inch 1000-1999 = joint 2 inch 6 inch 2000-2999 = joint 6 inch 12 inch 3000-3999 = joint 12 inch 24 inch 4000-4999 = joint 24 inch HW-D-0034 Joint Width HW-D-0034 Individual System Number
What is the makeup of the exterior wall? • Concrete panel, Spandrel Glass, Aluminum Panel, Brick Veneer, etc. • What supports the exterior wall? • Steel stud, aluminum mullions, etc. • What is the hourly rating you are looking for? • F rating (1 – 2 hour) • How big of a joint is required (inches) • Measured from edge of slab to nearest point of curtain wall • How much movement is required? • Must accommodate building movement (% of joint size) • Are there any special considerations? • Unique construction condition, environmental exposure
Example 3: OPL System - Fire Resistive Joints - Perimeter Barriers CEJ 148 H CEJ 205 P
Deciphering Alphanumeric Numbering - OPL - Fire Resistive Joints - Perimeter Fire Barriers First Three Alpha Characters– identify the type of construction CEJ = Construction/Expansion Joints CEJ148 H CEJ205 P Construction/Expansion Joint
Deciphering Alphanumeric Numbering - OPL - Fire Resistive Joints - Perimeter Fire Barriers Numeric Digits– identify the individual system number CEJ148H CEJ205P Individual System Number
Deciphering Alphanumeric Numbering - OPL - Fire Resistive Joints - Perimeter Fire Barriers Suffix– identify the type of joint system F = Floor-to-Floor H = Head-of-Wall W = Wall-to-Wall P = Perimeter FW = Floor-to-Wall CEJ 148H CEJ 205P Type of Joint System
Engineering Judgments (EJs): • What are they? • When are they acceptable? • When are they not appropriate? • What are the guidelines?
Engineered Judgements
When are they acceptable? • When tested systems do not exist. • When modifying the application is unrealistic. • When existing test data supports the interpolation. • When the author has experience with and knowledge of the conditions. • When an illustration is provided to aid in installation.
Sources of Engineering Judgements • Manufacturer • Third party labs (UL) • Fire Protection Engineer • Professional Engineer Must be based on sound engineering practice and knowledge of both field application and capabilities of system components
According to the International Firestop Council “listed firestop systems can be broadened within the context of their originally tested and rated conditions through the careful and restricted application of accepted engineering principles and fire protection testing guidelines.”
About the IFC The International Firestop Council is a not-for-profit association of manufacturers, distributors and installers of fire protective materials and systems.IFC's mission is to promote the technology of fire containment in modern building construction through research, education and development of safety standards and code provisions.
