Tests for Fire Resistance of Building Joint Systems
Standards: ASTM E 1966UL 2079
Test Items: Building Joint Systems Including:• floor-to-floor• floor-to-wall• head-of-wall• wall-to-wall
Report: Fire rating in hours, i.e., 1, 2, 3 or 4 hours

Tests for Fire Resistance ofBuilding Joint Systems
• ASTM E 1966 & UL 2079
• All Model Building Codes Now RequireCycling per ASTM E 1399
• Time temperature curve (ASTM E 119)
• Must meet Assembly Rating (T Rating) criteria
– 250° F + ambient average (ASTM E 1966)
– Any 1 thermocouple over 325° F + initial temp (UL 2079)
• Hose stream applicable to walls and wall tops
