UL Standards & Engagement has released the 6th Edition of UL 9540A, the standard test method for Evaluating Thermal runaway Fire Propagation in Battery Energy Storage Systems (BESS). The updated standard outlines critical testing protocols for assessing fire and explosion hazards associated with battery systems.
This revision is crucial for improving safety protocols for BESS installations, addressing industry concerns related to thermal runaway. The test data generated under UL 9540A is used to determine safe installation practices and adequate fire protection measures, as required by codes such as NFPA 855, the Standard for the Installation of Stationary Energy Storage Systems.
The updated standard will affect the design, testing, and certification requirements for battery storage systems. Fire protection engineers, manufacturers, and installers must familiarize themselves with the updated requirements to ensure compliance and the safety of BESS installations.
The evolution of UL 9540A is expected to continue driving innovation in fire suppression and mitigation technologies specifically designed for the unique challenges of battery storage applications, leading to new fire protection strategies in the field.
