ASTM E119 is a test method that is used to evaluate the fire resistance of building components and assemblies, such as walls, floors, and roofs. The test method is designed to evaluate the ability of these components and assemblies to contain a fire, prevent its spread, and maintain their structural integrity for a specified period of time.
During the test, a specimen of the building component or assembly is installed in a furnace and exposed to a standardized fire curve that simulates the heat and flames of a real-world fire. The fire curve is designed to represent the time-temperature relationship of a typical building fire, with the temperature gradually increasing over time.
The test measures several parameters including:
- Fire resistance rating:
This is the length of time that the specimen is able to maintain its structural integrity and prevent the spread of fire to the unexposed side of the specimen. The fire resistance rating is expressed in minutes and is based on the time it takes for the specimen to fail, as determined by criteria such as deflection, stability, and insulation.

- Thermal transmission:
This is the amount of heat that is transmitted through the specimen from the exposed side to the unexposed side during the test. The thermal transmission is expressed in kW/m² and is used to evaluate the insulation properties of the specimen.

- Hose stream test:
After the fire resistance test is completed, the specimen is subjected to a hose stream test in order to evaluate its ability to resist water penetration and maintain its structural integrity.

ASTM E119 is a widely recognized and accepted test method for evaluating the fire resistance of building components and assemblies. The test results can be used to verify compliance with building codes and standards, and to help ensure the safety of buildings and their occupants in the event of a fire.
