Samsung SDI 1st to meet global indoor battery fire safety standard

Samsung SDI announced its UPS batteries became the first in the industry to pass UL Solutions' Indoor Large-Scale Fire Test, a key safety standard for AI data centers. The test confirmed that a fire in one battery module did not spread to adjacent racks, with no gas release or explosion. This certification strengthens Samsung SDI's position in the growing AI data center market.

Samsung SDI said Tuesday its uninterruptible power supply UPS batteries have become the first in the industry to pass a global indoor fire safety test, bolstering its competitiveness in the fast-growing artificial intelligence AI data center market. The battery maker said its UPS batteries met all criteria in UL Solutions' Indoor Large-Scale Fire Test LSFT , becoming the first in the world to meet the standard. UPS systems provide emergency power during outages or voltage fluctuations and are considered critical infrastructure for AI data centers, where uninterrupted power is essential. The Indoor LSFT, introduced by UL Solutions earlier this year, evaluates whether a fire intentionally ignited in a battery module spreads to adjacent racks or systems under conditions that simulate real-world UPS operations. During the test, the battery module in which thermal runaway was intentionally initiated was completely consumed by fire, but the flames did not spread to adjacent racks. According to Samsung SDI, no gas release, explosion or rupture was observed, and the system met all required
