This standard BS EN 60952-2:2013 Aircraft batteries is classified in these ICS categories:
29.220.20 Acid secondary cells and batteries
49.060 Aerospace electric equipment and systems
IEC 60952-2:2013 defines the physical design, construction and material requirements for nickel-cadmium and lead-acid aircraft batteries containing vented or valve-regulated cells or monoblocs. The batteries are used for both general purposes and specific aerospace applications. This third edition cancels and replaces the second edition published in 2004. This new edition includes those formats that can be standardized along with their connectors and electrical interfaces.
