Electrostatics - Part 5-1: Protection of electronic devices from electrostatic phenomena - General requirements (IEC 61340-5-1:2024)
IEC 61340-5-1:2024 applies to organizations that: manufacture, process, assemble, install, package, label, service, test, inspect, transport, or otherwise handle electrical or electronic parts, assemblies and equipment with withstand voltages greater than or equal to 100 V human body model (HBM) and 200 V charge device model (CDM). Also, protection from isolated conductors is addressed by limiting the voltage on isolated conductors to less than 35 V. ESDS with lower withstand voltages can require additional control elements or adjusted limits. Processes designed to handle items that have lower ESD withstand voltage(s) can still claim compliance to this document. This document provides the requirements for an ESD control program. IEC TR 61340-5-2 provides guidance on the implementation of this document. This document does not apply to electrically initiated explosive devices, flammable liquids, gases, and powders. The purpose of this document is to provide the administrative and technical requirements for establishing, implementing, and maintaining an ESD control program (hereinafter referred to as the “program”). This edition includes the following significant technical changes with respect to the previous edition:
a) definitions have been added to the document;
b) updates to product qualification requirements;
c) subclause 5.3.3 now includes a reference to groundable static control garment systems;
d) Table 2 was replaced;
e) subclause 5.3.4.2 was updated to define what an insulator is;
f) subclause 5.3.4.3 was updated to include a definition for isolated conductor;
g) Table 3 was updated, technical items added, including a reference to IEC 61340-5-4 for compliance verification testing;
h) Table 4 was added as a summary of the requirements in IEC 61340-5-3 and to include requirements for compliance verification of packaging;
i) Annex A was replaced: the former Annex is no longer required. Annex A are examples of tailoring.

114 INTRODUCTION
115 This part of IEC 61340 covers the requirements necessary to design, establish, implement
116 and maintain an electrostatic discharge (ESD) control program for activities that: manufacture,
117 process, assemble, install, package, label, service, test, inspect, transport or otherwise
118 handle electrical or electronic parts, assemblies and equipment susceptible to damage by
119 electrostatic discharges greater than or equal to 100 V human body model (HBM), 200 V
120 charged device model (CDM) and 35 V on isolated conductors. Isolated conductors were
121 historically represented by machine model (MM). The 35 V limit is related to the level
122 achievable using ionizers specified in this standard. The MM test is no longer required for
123 qualification of devices, only the HBM and CDM tests are. The requirements relating to MM
124 are retained in this standard for process control of isolated conductors only.
125 Any contact and physical separation of materials or flow of solids, liquids, or particle-laden
126 gases can generate electrostatic charges. Common sources of ESD include charged:
127 personnel, conductors, common polymeric materials, and processing equipment. ESD
128 damage can occur when:
129 • a charged person or object comes into contact with an ESD sensitive device (ESDS);
130 • an ESDS comes into direct contact with a highly conductive surface while exposed to an
131 electrostatic field;
132 • a charged ESDS comes into contact with another conductive surface which is at a different
133 electrical potential. This surface can be grounded or ungrounded.
134 Examples of ESDS are microcircuits, discrete semiconductors, thick and thin film resistors,
135 hybrid devices, printed circuit boards and piezoelectric crystals. It is possible to determine
136 device and item susceptibility by exposing the device to simulated ESD events. The E
