Scope

The requirements in this document evaluate the fire characteristics of a battery energy storage system that undergoes thermal runaway. The data generated will be used to determine the fire and explosion protection required for an installation of a battery energy storage system. These requirements apply to Battery Energy Storage Systems intended for installation@ operation and maintenance in accordance with the International Fire Code (IFC)@ the National Electrical Code@ NFPA 70@ other energy storage system codes@ and the manufacturer??s installation instructions. The criteria established within this document is designed to meet the objectives of the International Fire Code (IFC)@ the Fire Code@ NFPA 1@ and other energy storage system codes relative to fire propagation hazards and fire mitigation methods from a single battery energy storage system unit.
