1. Introduction
Scope of IEC SC21A :
“To prepare standards regarding product and test specifications
for all secondary cells and batteries of sealed and vented
designs containing alkaline or other non-acid electrolytes.
To support other technical committees standardizing application
oriented systems using secondary cells and batteries”

l Secondary cell and batteries

l Sealed and vented design
l Alkaline or other non–acid electrolytes

è Safety standards of Ni-Cd, Ni-MH and Li-ion have to

be developed in SC21A.

2. Existing safety standard in IEC SC21A
IEC 62122 Ed.2 includes new important requirements of cell
operating region and FISC (Forced Internal Short Circuit) test.
n Cell operating region
n FISC test
FISC test was developed in JIS C 8714 and has been mandatory by law in
Japan since 2008. The number of incidents has been decreased significantly
since there in Japan
è To introduce in IEC 62133 Ed. 2 by Japan NC.
