IEC 60952-3:2013 defines requirements for the product specification as well as procedures for a Declaration of Design and Performance (DDP) 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. The specific topics addressed in this part of 60952 series serve to establish acceptable quality standards required to qualify a battery as airworthy as defined in Clause 3 of IEC 60952-1:2013. This third edition cancels and replaces the second edition published in 2004. This new edition includes requirements for defining the declaration of performance and specification details between supplier and purchaser.
