Understanding EN vs AS/NZS Fire Testing: A Technical Deep Dive into Passive Firestop Performance

See how EN’s stricter criteria compare with AS 1530.4 and what this means for real‑world firestop reliability.

Engineers increasingly face international products tested to EN 1366‑3/4 and EN 13501 — but what does this mean for performance under AS 1530.4 and NZ code requirements? This session clarifies the key differences: stricter EN furnace control, more severe integrity and insulation checks, and additional performance metrics not captured by AS/NZS. We illustrate why EN certification is often considered a higher benchmark and how EN‑tested passive firestop systems can be used to meet (and in many cases exceed) NZ’s FRL expectations. An educational session designed to build confidence, cut through confusion, and elevate the quality of your fire‑safety specifications.
