Which standard is used for testing through-penetration firestop systems?

The standard used for testing through-penetration firestop systems is ASTM E814. This standard provides the methodology for evaluating the performance of firestop systems that are designed to resist the passage of fire through openings created by penetrations in fire-rated assemblies, such as walls and floors.

ASTM E814 specifically focuses on the ability of these systems to maintain fire and smoke resistance ratings, ensuring that they effectively contain fire and prevent its spread through penetrations. The testing procedures defined in this standard include the use of standardized test conditions and criteria to evaluate how well a firestop system performs under controlled fire exposure.

In contrast, the other options pertain to different areas of standards and testing. ISO 9001 is related to quality management systems and does not specifically address firestop systems. ASTM D1929 focuses on the flash point and ignition properties of plastics and is thus unrelated to firestop testing. NFPA 25 deals with the inspection, testing, and maintenance of water-based fire protection systems, which again does not apply to through-penetration firestop systems.
