According to the standards, fire-resistant joint systems must be tested in accordance with which standards?

Fire-resistant joint systems are crucial in maintaining the integrity of fire barriers in buildings, and they must be tested to ensure they can perform as required during a fire event. The appropriate standards for testing these joint systems are both ASTM E 1966 and UL 2079, as each provides specific criteria and protocols for evaluating the performance of these systems.

ASTM E 1966 focuses on the fire tests of fire-resistive joint systems, assessing how well these joints can withstand fire and maintain their functionality during an incident. UL 2079, on the other hand, offers a similar framework but includes additional aspects of the system's performance, such as movement capabilities, which are essential for maintaining the effectiveness of the fire barrier in a building.

By adhering to both standards, manufacturers and inspectors can ensure that fire-resistant joint systems are thoroughly tested and certified to meet the necessary safety requirements, contributing to the overall fire safety strategy of commercial buildings. This dual adherence ensures comprehensive evaluation, leading to more resilient structures in the event of a fire.
