Addressing Thermal Propagation Hazard of Battery Energy Storage Systems – UL 9540A Test Method Recorded Webinar


Fire departments and building inspectors are concerned over the use of lithium-ion batteries and battery energy storage systems (BESS) to be permanently installed in mixed occupancy or high-rise buildings. As a result, installation codes have been recently updated to require large scale fire testing to evaluate the risk of fire propagation from a faulty unit. These requirements for testing did not include a methodology, which UL has now provided with the publication of the UL 9540A Test Method. The test method for evaluating thermal runaway fire propagation in BESS will bring clarity on the performance of a BESS under a possible thermal event that can occur in the life of the system.



Topics Covered

  • UL 9540A Test Method Brings Clarity to Industry and Code Authorities – this webinar will help manufacturers and system integrators understand how to meet the IFC 2018 and NFPA 855 large scale fire and fault testing by evaluating fire propagation.
  • The audience will gain perspective of how they can better form insurance policies, develop mitigation techniques, and support the advancement of safe, secure, and sustainable next generation of electrical infrastructure.
  • For Insurance & Fire Mitigation professionals understanding what the test method provides is critical for assessing building and infrastructure risk and loss prevention.
