 EN 14604 vs UL 268 – Sensitivity Test Highlights

Ø EN14604 emphasizes photoelectric (optical) detection, ideal for slow-smoldering fires common in homes.

Ø UL 268 covers both flaming and smoldering fire tests, with more complex sensitivity calibration.

Ø For European markets, EN 14604 with CE marking is mandatory.

Ø For North American markets, UL 268 is the recognized standard.

Ø Understanding these differences helps ensure compliance and optimal fire safety performance across regions.
