IEC 62485‑2 provides practical, risk‑based requirements to make VRLA stationary battery installations safe in normal and fault conditions. Designers must integrate electrical, mechanical, ventilation, monitoring, firefighting and procedural controls, and verify compliance with local codes and manufacturer limits.
IEC 62485-2 applies primarily to stationary secondary batteries and battery installations. It details the principal measures for protection against hazards generated by electricity, gas emissions, and electrolytes. iec 624852 pdf
