Defines the general requirements for the protection of electrostatic discharge sensitive devices (ESDS) from electrostatic discharge and fields. Applicable only to the manufacture and use of electronic devices. Covers how to design, use and control a protected area to ensure that electrostatic sensitive devices, having a withstand threshold voltage of 100 V (human body model) or higher, can be handled with a minimum risk of damage resulting from electrostatic phenomena.
