Compliance with safety standards is often a prerequisite for product certification, market access, and legal liability protection.
Global Harmonization: International safety standards promote global harmonization and interoperability of LiFePO4 batteries, facilitating trade, technology transfer, and market acceptance across different regions and jurisdictions. Harmonized standards streamline product testing, certification, and regulatory compliance, reducing barriers to entry and promoting innovation.

Key Safety Standards for LiFePO4 Batteries

IEC 62133: The International Electrotechnical Commission (IEC) 62133 standard specifies safety requirements for secondary (rechargeable) lithium cells and batteries, including LiFePO4 batteries, intended for use in portable electronic devices, power tools, and other applications. The standard covers aspects such as electrical, mechanical, and environmental performance, as well as testing methodologies for evaluating battery safety and reliability.
UN/DOT Transportation Regulations: LiFePO4 batteries are subject to transportation regulations established by the United Nations (UN) and the U.S. Department of Transportation (DOT) to ensure safe handling, packaging, and transport of hazardous materials, including lithium batteries. These regulations specify packaging requirements, labeling, documentation, and handling procedures for the transportation of LiFePO4 batteries by air, sea, road, and rail.
UL 1642 and UL 2054: Underwriters Laboratories (UL) standards 1642 and 2054 address the safety of lithium batteries, including LiFePO4 batteries, for use in stationary and portable applications, respectively. UL 1642 covers lithium batteries intended for use in larger-scale applications such as energy storage systems, while UL 2054 applies to batteries used in consumer electronics, toys, and other portable devices.
ISO 26262: ISO 26262 is an international standard for functional safety in automotive systems, including LiFePO4 batteries used in electric vehicles (EVs) and hybrid electric vehicles (HEVs). The standard provides guidelines for assessing and managing safety risks throughout the automotive development lifecycle, from concept phase to production, operation, and decommissioning.
