This standard specifies the safety requirements of lithium ion cells and batteries used in portable electronic equipment.
This standard is applicable to lithium ion cells and batteries used in portable electronic equipment (hereinafter referred as cells and batteries); examples of portable electronic equipment which belong to this standard are as follows:
a) Portable office products: laptop, PDA, etc.
b) Mobile communication products: cellphone, cordless telephone, Bluetooth earphone, interphone, etc.
c) Portable audio/video products: portable television, portable DVD player, MP3/MP4 player, camera, video camera, recording pen, etc.
d) Other portable products: electronic navigator, digital photo frame, game console, eBook, etc.
Above listed portable electronic equipment do not cover all products; therefore non-listed products are possibly in the scope of this standard.
For lithium ion cells or batteries used for portable electronic equipment at specific occasions such as on the vehicle, ship and plane, and in special fields such as medical treatment, mining and seabed operation, there are possibly additional requirements.
