Electrostatics - Part 5-4: Protection of electronic devices from electrostatic phenomena - Compliance verification

Electrostatics - Part 5-4: Protection of electronic devices from electrostatic phenomena - Compliance verification

IEC TS 61340-5-4:2021(E) describes compliance verification testing for technical items that are included in ESD control programs, such as those specified in IEC 61340-5-1.
Test methods are based on those specified in IEC 61340-5-1 and other parts of the IEC 61340 series, and are simplified where necessary for the purposes of compliance verification, to be performed by competent personnel.
Users can, by reference to this document in their compliance verification plan, adopt the necessary test methods described herein without change or addition. Alternatively, test methods described in this document can be adapted to match the requirements of their own ESD control program, provided deviations in equipment or procedure are documented in their compliance verification plan.
Compliance verification test frequency is not specified in this document. Guidance on how users can consider compliance verification test frequency is given in informative Annex A.
Product qualification is excluded from the scope of this document.
This first edition cancels and replaces IEC TR 61340-5-4 published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TR 61340­5-4:
test methods in the main body of the document have been made normative, and consequently normative references have been added;
the term "ESD ground" has been added and defined;
description of equipment for measuring low resistance has been added;
user specified electrodes, including surface resistance bar electrodes, are permitted to be used for resistance measurements;
an informative annex on verification of compliance verification test equipment has been added;
compliance verification of person-footwear-flooring systems by measuring body voltage has been moved to an informative annex.

Electrostatics - Part 5-1: Protection of electronic devices from electrostatic phenomena - General requirements

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.

IEC TS 61340-6-2:2023 applies to the interior design of public places, retail and office areas such as, but not limited to staircases, offices, meeting rooms, auditoriums, airports, train stations, shopping centres, restaurants and theatres. This document includes guidelines for architects, interior designers and facility managers.
Hazards, nuisances and other problems associated with electrostatic phenomena and the principles of their control are outlined. This document includes requirements and recommendations for materials, and products used to control static electricity.
The handling of electrostatic sensitive components is described in IEC 61340-5-1 and the avoidance of hazards due to static electricity in explosive atmospheres is presented in IEC TS 60079-32-1. The requirements for electrostatic control in healthcare facilities are specified in IEC 61340-6-1. The guidance in this document is not intended to replace or supersede the requirements of the aforementioned standards and technical specification, but can be used in association with them to establish appropriate electrostatic control measures.
These guidelines do not replace or supersede any requirements for personnel safety specified in other standards or codes of practice.

IEC PAS 61340-5-6:2022 describe a set of methodologies, techniques, and tools that can be used to characterize a process where ESD sensitive (ESDS) items are handled. The process assessment covers risks by charged personnel, ungrounded conductors, charged ESDS items, and ESDS items in an electrostatic field. This document applies to activities that manufacture, process, assemble, install, package, label, service, test, inspect, transport, or otherwise handle electrical or electronic parts, assemblies, and equipment susceptible to damage by electrostatic discharges. This document does not apply to electrically initiated explosive items, flammable liquids, or powders. The document does not address program management, compliance verification, troubleshooting, or program manager/coordinator certification. In this version of the document, risks due to electromagnetic sources that produce AC fields are not considered.

Electrostatics - Part 5-3: Protection of electronic devices from electrostatic phenomena - Properties and requirements classification for packaging intended for electrostatic discharge sensitive devices

IEC 61340-5-3:2022 defines the ESD protective packaging properties required to protect ESD sensitive devices (ESDSs) through all phases of production, rework and maintenance, transport and storage. Test methods are referenced to evaluate packaging and packaging materials for these product and material properties. Performance limits are provided.
This document does not address protection from electromagnetic interference (EMI), electromagnetic pulsing (EMP) or protection of electrically initiated explosive materials or devices.
This edition includes the following significant technical changes with respect to the previous edition:
a) reference to IEC 61340-4-10 was removed;
b) material resistance property "electrostatic field shielding" was removed;
c) the requirement for electrostatic discharge shielding was changed from 50 nJ to 20 nJ;
d) Table 1 – footnote "b" was changed to mention the two-point probe in IEC 61340-2-3;
e) "shall be marked" was changed to "should be marked" in 7.2.2 and 7.2.3;
f) Table 3 – the classification symbol and the primary function code F was removed;

IEC TR 61340-5-5:2018(E) discusses packaging material requirements for electrostatic discharge sensitive items (ESDS) as well as non–ESDS which can apply to packaging materials such as embossed carrier tape, trays, tubes (stick magazines), rails and others used in back end line processing and parts handling where test methods described in other standards are, for the most part, inadequate. Issues related to electrostatic charge generation, electrostatic attraction and repulsion are included. The recommendations and discussions within this document can also be applicable to other types of packaging that cannot be evaluated by other means.
This document discusses the issues related to
1) technical considerations for packaging material selection and packaging system design,
2) packaging material specifications for electrostatic control,
3) existing test methods and their limitations for packaging materials,
4) suggestions for the evaluation of small dimension packaging materials, and
5) industry common practices.
