ANSI/CAN/UL/ULC 1487:2025

Scope 1.1 This Standard addresses battery containment enclosures intended to mitigate the heat, fire, and deflagration hazards that can result from lithium-ion battery thermal runaway. 1.2 These requirements do not address the toxicity hazards associated with thermal runaway of lithiumion cells, batteries, battery packs, or battery-powered devices. 1.3 A battery containment enclosure covered by this Standard may be used for storage and/or transport of lithium-ion cells, batteries, battery packs, and battery-powered devices. 1.4 A battery containment enclosure covered by this Standard is not intended to be used with lithium-ion cells, batteries, battery packs, and/or battery-powered devices combined with other potential hazardproducing materials, such as combustible or flammable liquids, acids, bases, combustible metals or dusts, or compressed gases. 1.5 These requirements are not intended to supersede applicable transportation, packaging, and shipping regulations enacted by the authority having jurisdiction for transporting lithium-ion cells, batteries, battery packs, or battery-powered devices. Battery containment enclosures used for transportation of lithium-ion cells, batteries, battery packs, or battery-powered devices shall comply with all applicable transportation, packaging, and shipping requirements and regulations. NOTE: See Annex F for additional information on transportation of lithium-ion batteries. 1.6 A battery containment enclosure covered by this Standard may include integral systems and/or internal electrical power distribution for charging lithium-ion cells, batteries, battery packs, or batterypowered devices. 1.7 These requirements do not address energy storage systems, as these systems are intended to be covered by UL 9540, the Standard for Energy Storage Systems and Equipment, and/or UL 9540A, the Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems. NOTE: See Annex E for further explanation. 1.8 This Standard does not cover hazard mitigation systems of a battery containment enclosure unless they are integral to the battery containment enclosure product. 1.9 This Standard covers battery containment enclosures for indoor and outdoor installations and/or portable/mobile battery containment enclosures. Battery containment enclosures covered by this Standard are intended to be used in ordinary locations in non-residential occupancies, dedicated non-habitable installation locations within multi-occupancy residential buildings, laboratory non-hazardous environments, and/or outdoors, all in accordance with governing building and fire codes and regulations. These products are not intended to be installed or used in residential dwellings.
