RTCA DO-227

This document contains test, performance and safety evaluation requirements for primary cells and batteries containing lithium metal or lithium alloys. Guidance is also provided on design, safety, handling and storage of these items. This document defines levels of severity of cell and of battery testing to enable cell and battery manufacturers to qualify their products in accordance with their intended use. Equipment designers and manufacturers in turn can select cells and batteries whose safety and performance have been demonstrated at levels appropriate to the battery environment within the equipment and to the required performance.
