IEC 62485-2 is an international standard establishing safety requirements for stationary secondary batteries, covering installation, ventilation, and protective measures against electric shock or electrolyte leakage. The standard applies to lead-acid and NiCd/NiMH systems with up to 1,500 V DC, crucial for applications like UPS, telecommunications, and solar energy storage. For more technical details, visit IEC. IEC 62485-2:2010

  1. The IEC "Preview" Function: On the IEC webstore, every standard has a free preview showing the table of contents, scope, and first 10 pages. This often contains 80% of the high-level rules you need.
  2. Nationalized Adoption Documents: Some countries adopt 62443 as a national standard with commentary. For example, ISA-62443 (from ISA in the US) is identical but often cheaper or available to members for free.
  3. White Papers from Vendors: Companies like Rockwell Automation, Siemens, and Palo Alto Networks publish "IEC 62443 Compliance Guides" that summarize the PDF requirements in practical language. These are free and legal.
  4. University Access: If you are a student, many technical universities purchase site licenses for IEC standards. Check your university library portal.

Requirements for the dismantling and recycling of batteries to minimize environmental impact. Relationship with Other Standards IEC 62485-1:

Mechanical and handling considerations

  • Lifting, handling and storage procedures to avoid damage and shorting; mechanical aids for heavy blocks or racks.
  • Use of appropriate PPE: acid-resistant gloves, goggles/face shield, aprons, and eye-wash/neutralizing stations nearby.
  • Assembly and maintenance clearances and mechanical retention to prevent tipping or collapse.

Important note: For large lithium-ion energy storage systems (ESS) over 1 kWh, other standards (IEC 62619, UL 9540, NFPA 855) may also apply in parallel.
