Specifies the general requirements for the protection of electrostatic discharge devices (ESDs) from electrostatic discharges and fields. Also specifies methods for the design, use and control of a protected area to ensure that ESDs, 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. This Interim Australian Standard is identical in technical content to and reproduced from IEC 61340-5-1:1998 and its Corrigendum 1999-02.

This technical report specifies the general requirements for the protection of electrostatic discharge sensitive devices (ESDS) from electrostatic discharges and fields. It applies only to the manufacture and use of electronic devices. This technical report specifies 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. Normal precautions given in this report are applicable for areas with clean room types in excess of ISO 14644-1 class 5. Alternative precautions may be required in clean rooms of ISO 14644-1 class 5 or less if contamination is formed as a result of using the procedures specified in this technical report. Although this technical report does not include requirements for personnel safety, attention is drawn to the need for all concerned to comply with relevant local statutory requirements regarding the health and safety of all persons in all places of work, including those covered by this technical report. Generally, there is no minimum value of resistance for the protection of ESDS (see 3.2). However, a minimum resistance value may be required for the safety of personnel. See the relevant requirements and/or publications IEC 61010-1, IEC 60479, IEC 60536, IEC 60364.
