Scope:

1.1 The test methodology in this standard evaluates the fire characteristics of a battery energy storage system that undergoes thermal runaway.

1.2 The data generated will be used to determine the fire and explosion protection required for an installation of a battery energy storage system intended for installation, operation and maintenance in accordance with the International Fire Code (IFC), the Fire Code, NFPA 1, the National Electrical Code, NFPA 70, the Canadian Electrical Code, Part I Safety Standard for Electrical Installations, C22.1, the National Electrical Safety Code (NESC), IEEE C2, other energy storage system codes, and the manufacturer's installation instructions.

1.3 Fire protection requirements not related to battery energy storage system equipment are covered by appropriate installation codes.

1.4 See Figure 1.1 for a schematic of the test sequence in this standard. See Appendix A which explains:

       a)     The purpose of the tests included in this Test Method;

       b)     Explanation of individual tests; and

       c)     Interpretation and application of the results.

Project need:

To develop a Joint Canada-U.S. National Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems.
