Does ASTM E814/UL 1479 require a hose stream test?

The requirement for a hose stream test under ASTM E814/UL 1479 is a critical aspect of ensuring the effectiveness of firestop systems. This standard evaluates the fire-resistance performance of through-penetrations in fire-rated walls and floors. After fire exposure, a hose stream test is necessary to simulate the impact of firefighting efforts on the firestop system.

The hose stream test measures how well the system can withstand the physical stresses associated with a water hose being directed at it after a fire event. This is crucial because, during firefighting efforts, the integrity of firestop systems can be compromised due to the forcible impact of water and debris. Therefore, including this test helps to ascertain not only the thermal resistance of the firestop material but also its ability to maintain structural integrity under realistic conditions seen during an actual fire response.

The other options suggest that no hose stream test is required, which underestimates the thoroughness needed for evaluating firestop compliance with real-world fire scenarios. Options implying limited application to specific contexts also misrepresent the comprehensive nature of the test's requirement, as both residential and commercial applications must prioritize fire safety standards consistently.
