IEC 60952-2:2013

Overview

IEC 60952-2:2013 is an international standard issued by the International Electrotechnical Commission (IEC) that specifies the design and construction requirements for aircraft batteries. This standard primarily covers nickel-cadmium and lead-acid batteries used in aerospace applications, including both vented and valve-regulated cell types and monobloc designs. As the third edition, this 2013 publication replaces the 2004 edition, introducing updated specifications, including standardized battery formats, connectors, and electrical interfaces.

The standard ensures that aircraft batteries meet stringent criteria for reliability, safety, and performance to support the critical power needs of modern aircraft systems. IEC 60952-2 serves as a key reference for manufacturers, aerospace engineers, and regulatory bodies involved in the development, certification, and maintenance of aircraft battery technologies.
