What is large scale fire testing?

Unlike UL 9540A testing, which may only lead to the release of flammable gases without ignition, large-scale fire testing forces a fire condition in one ESS enclosure to assess if thermal runaway and fire propagation will occur in adjacent enclosures. Why are AHJs and regulators now requiring Large Scale Fire Testing?

Why are AHJs asking for large-scale fire testing?

AHJs and regulators are asking for large-scale fire testing in addition to the standard UL 9540A tests because UL 9540A does not always result in a fire condition. Although thermal runaway can occur, it may not ignite, leaving uncertainty about the potential for fire spread.

Why do we need large-scale fire tests?

The International Fire Code Commentary emphasizes the need for large-scale fire tests to document that fire propagation between units will not occur and to gather data for risk assessments in different installation settings. What is the purpose and scope of TS-800?

What is TS-800 fire testing?

TS-800 aligns with requirements in codes like the California Fire Code and the International Fire Code, offering a much-needed standardized approach to large-scale fire testing. CSA Group is uniquely positioned as one of the few testing laboratories worldwide capable of providing large-scale fire testing services.
