This International Standard 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 there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, the former takes precedence. (e.g. IEC 62675) Since this standard covers batteries for various industrial applications, it includes those requirements, which are common and minimum to the various applications.
