IEC 62660-2 Thermal Runaway Testing for Lithium-Ion Batteries

Comprehensive Guide to IEC 62660-2 Thermal Runaway Testing for Lithium-Ion Batteries Laboratory Testing Service by Eurolab

IEC 62660-2, published in 2014, is a standard that governs the thermal runaway testing of lithium-ion batteries. This standard is part of the IEC 62660 series, which covers various aspects of battery safety testing. The standard is developed by the International Electrotechnical Commission (IEC) and is widely accepted globally.

Thermal runaway is a phenomenon where a batterys temperature rises uncontrollably, leading to a fire or explosion. Lithium-ion batteries are prone to thermal runaway due to their chemistry and design. IEC 62660-2 provides guidelines for testing the thermal runaway behavior of lithium-ion batteries under various conditions.

Legal and Regulatory Framework

The use of lithium-ion batteries is governed by various regulations and standards, including those related to safety, environmental protection, and product liability. In Europe, the EU Battery Directive (2006/66/EC) sets requirements for battery safety, including thermal runaway testing.

In the United States, the Federal Aviation Administration (FAA) and the Pipeline and Hazardous Materials Safety Administration (PHMSA) regulate the transportation of lithium-ion batteries. The International Air Transport Association (IATA) also has guidelines for the safe transportation of lithium-ion batteries.

International and National Standards

IEC 62660-2 is an international standard that is widely adopted globally. Some countries have national standards that align with IEC 62660-2, while others may have additional requirements. For example:
