- UL 2079 Fire tests of Fire Resistive Joint Systems
- ASTM E119 Fire Test for Building Construction and Materials
- ASTM E1399 Standard Test Method of Cyclic Movement and Measuring the Minimum and Maximum Joint Widths of Architectural Joint Systems
- Australian Standard AS1530. Methods for fire tests on building materials, components and structures (Part 4: Fire-resistance tests of elements of building construction).
