Nomenclature The UL Fire Resistance Directory utilizes an alpha-numeric numbering system: Basic number system = ALPHA–ALPHA–NUMERIC The second letter(s) provide more information about the floor or wall : The four digit number describes the penetrating item(s): EXAMPLE: CAJ1150 F = FLOOR W = WALLS C = FLOORS OR WALLS (COMBINED) A = CONCRETE FLOORS WITH A MINUMUM THICKNESS LESS THAN OR EQUAL TO 5 IN. B = CONCRETE FLOORS WITH A MINUMUM THICKNESS GREATER THAN 5 IN. C = FRAMED FLOORS D = STEEL DECKS IN MARINE VESSELS E = FOR-CEILING ASSEMBLIES CONSISTING OF CONCRETE WITH MEMBRANE PROTECTION F THRU I = NOT USED AT PRESENT TIME J = CONCRETE OR MASONRY WALLS WITH A MINUMUM THICKNESS LESS THAN OR EQUAL TO 8 IN. K = CONCRETE OR MASONRY WALLS WITH A MINUMUM THICKNESS GREATER THAN 8 IN. L = FRAMED WALLS M = BULKHEADS IN MARINE VESSELS N = COMPOSITE PANEL WALLS O THRU Z = N OT USED AT PRESENT TIME 0000 – 0999 BLANK OPENINGS 1000 – 1999 M ETAL PIPE, CONDUIT OR TUBING 2000 – 2999 N ONMETALLIC PIPE CONDUIT OR TUBING 3000 – 3999 CABLES 4000 – 4999 CABLE TRAYS 5000 – 5999 INSULATED PIPES 6000 – 6999 M ISCELLANEOUS ELECTRICAL (BUSWAY) 7000 – 7999 M ISCELLANEOUS MECHANICAL 8000 – 8999 M IXED PENETRATING ITEMS 9000 – 9999 R ESERVED FOR FUTURE USE C = FLOOR OR WALL PENETRATION A = CONCRETE FLOOR 5" OR LESS J = CONCRETE OR MASONRY WALLS 8" OR LESS The first letters identify the type of joint: The third letter signifies the movement capabilities of the joint system: The four digit number describes the nominal joint width: EXAMPLE: HWD0042 CJ = CONTINUITY HEAD OF WALL FF = FLOOR-TO-FLOOR WW = WALL-TO-WALL FW = FLOOR-TO-WALL HW = HEAD-TO-WALL CG = WALL-TO WALL JOINTS INTENDED AS CORNER GUARDS BW = BOTTOM OF WALL S = NO MOVEMENT (STATIC) D = A LLOWS MOVEMENT (DYNAMIC) 0000 – 0999 L ESS THAN OR EQUAL TO 2" 1000 – 1999 G REATER THAN 2" AND LESS THAN OR EQUAL TO 6" 2000 – 2999 G REATER THAN 6" AND LESS THAN OR EQUAL TO 12" 3000 – 3999 G REATER THAN 12" AND LESS THAN OR EQUAL TO 24" 4000 – 4999 GREATER THAN 24" HW = HEAD-OF-WALL D = A LLOWS MOVEMENT (DYNAMIC) 1150 = M ETAL PIPE, CONDUIT OR TUBING The first letter represents what is being penetrated: Through – Penetrations Joint Systems Perimeter Fire Containment Systems The third letter signifies the movement capabilities of the joint system: The four digit number describes the nominal joint width: CW S = NO MOVEMENT (STATIC) D = A LLOWS MOVEMENT (DYNAMIC) 0000 – 0999 L ESS THAN OR EQUAL TO 2" 1000 – 1999 G REATER THAN 2" AND LESS THAN OR EQUAL TO 6" 2000 – 2999 G REATER THAN 6" AND LESS THAN OR EQUAL TO 12" The first letters identify the perimeter fire containment system: = CURTAIN WALL 0042 = L ESS THAN OR EQUAL TO 2" Hilti Firestop Saving lives through innovation and education 691
