Standard Test Method for Fire-Resistive Joint Systems

Importancia y uso:

5.1 This test method evaluates, under the specified test conditions: (1) the ability of a fire resistive joint system to undergo movement without reducing the fire rating of the adjacent fire separating elements and (2) the duration for which test specimens will contain a fire and retain their integrity during a predetermined test exposure.

5.2 This test method provides for the following measurements and evaluations where applicable:

5.2.1 Capability of the joint system to movement cycle.

5.2.2 Loadbearing capacity of the joint system.

5.2.3 Ability of the joint system to prohibit the passage of flames and hot gases.

5.2.4 Transmission of heat through the joint system.

5.2.5 Ability of the joint system, that is an extension of a wall, to resist the passage of water during a hose stream test.

5.3 This test method does not provide the following:

5.3.1 Evaluation of the degree by which the joint system contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion.

5.3.2 Measurement of the degree of control or limitation of the passage of smoke or products of combustion through the joint system.

5.3.3 Measurement of flame spread over the surface of the joint system.

Note 1: The information in 5.3.1 – 5.3.3 may be determined by other suitable fire test methods. For example, 5.3.3 may be determined by Test Method E84.

5.3.4 Evaluation of joints formed by the rated or non-rated exterior walls and the floors of the building.

5.4 In this procedure, the test specimens are subjected to one or more specific sets of laboratory test conditions. When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, this test method to predict changes to the characteristics measured. Therefore, the results are valid only for the exposure conditions described in this test method.
