scope:

This part of IEC 952 covers both 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 applications. The object of the present part is to define the physical design and construction requirements for aircraft batteries as well as the structure and contents of Declarations of Design and Performance (DDP) for the different battery types. A preferred range of aircraft batteries is specified in annex A but this part of IEC 952 may be used for other battery sizes, arrangements and ratings. For particular applications, other design requirements may be called for. These will be in addition to the requirements of this part and will be covered by specific documents.
