IEC 63115-2:2021 pdf free download Secondary cells and batteries containing alkaline or other non-acid electrolytes – Sealed nickel-metal hydride cells and batteries for use in industrial applications – Part 2: Safety
1 Scope
This document specifies designations, tests and requirements for the safe operation of sealednickel-metal hydride cells and batteries used in industrial applications excluding road vehicles.
When an lEC 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.lEC 62675).
Since this document covers batteries for various industrial applications,it includes thoserequirements which are common and minimum to the various applications.
