What does ASTM E814/UL 1479 standardize testing for?

The ASTM E814/UL 1479 standard specifically addresses the testing methods for Through-Penetration Fire Stops. This standard outlines the performance criteria and testing procedures to evaluate the effectiveness of firestop systems in preventing the spread of fire and smoke through openings created by pipes, cables, or other building elements that penetrate fire-rated walls and floors.

Through-penetration fire stops are critical in maintaining the integrity of fire-rated assemblies, ensuring that they provide the necessary resistance to fire passage for a designated time. By adhering to the ASTM E814/UL 1479 standards, manufacturers and installers can ensure that their firestop products are capable of functioning effectively under real fire conditions, contributing significantly to the overall fire safety of a building.

The other options refer to different aspects of fire protection. Fire exposure materials and passive fire protection systems relate to broader categories of fire safety, but do not focus specifically on the testing of through-penetration fire stops. Active fire suppression systems involve methods like sprinklers that actively combat fire, which is outside the scope of what ASTM E814/UL 1479 addresses.
