IEC 63115-2:2021 specifies designations, tests and requirements for the safe operation of sealed nickel-metal hydride cells and batteries used in industrial applications excluding road vehicles.
When an IEC International Standard specifying test conditions and requirements for cells used in special applications is in conflict with this document, the former takes precedence (e.g. IEC 62675).
Since this document covers batteries for various industrial applications, it includes those requirements which are common and minimum to the various applications.
