IEC 62485-2 sets international safety standards for stationary battery installations, focusing heavily on preventing hazardous hydrogen accumulation through proper ventilation. The standard mandates, and often requires, specialized ventilation to ensure hydrogen levels remain below 1% by volume, with specific guidelines for natural airflow or forced exhaust based on battery technology.
