Electrostatics - Part 4-3: Standard test methods for specific applications - Footwear

IEC 61340-4-3:2017 describes a test method for determining the electrical resistance of footwear (shoes, slippers or booties) used in the control of electrostatic potential on people. This document is suitable for use by the manufacturer of footwear as well as the end user. A method for measuring the electrical resistance of footwear alone is described and serves as a qualification test or an acceptance test for new footwear, or as a periodic test of in-use footwear. Although this document does not include requirements for personal safety, footwear used within the scope of this document in all places of work is regulated by the relevant local statutory requirements regarding the health and safety of all persons. Insulating footwear is not included within the scope of this document although the electrical resistance measurement techniques can be applicable. This edition includes the following significant technical changes with respect to the previous edition: a) classification of footwear as electrostatic conductive or electrostatic dissipative has been removed – classification is not specified; b) environmental classes for laboratory testing have been removed – one set of conditions for pre-conditioning, conditioning and testing is specified; c) reference to IEC 61340-2-3 for measuring the resistance of the counter electrode inserted inside footwear has been removed.

Overview

EN IEC 61340-4-3:2018 (Electrostatics - Part 4-3: Standard test methods for specific applications - Footwear) defines a standardized method for measuring the electrical resistance of footwear (shoes, slippers, booties) used to control electrostatic potential on people. The standard is intended for both manufacturers and end users to perform qualification, acceptance and periodic testing of footwear used in electrostatic control programs. Insulating footwear is excluded from the scope, although the measurement techniques may be applicable.

Key topics and requirements

• Purpose: Measure electrical resistance of footwear alone as a basis for qualification, acceptance or in-use periodic testing.
• Test specimens: Minimum sample size for qualification tests is three pairs; cleaning as per manufacturer’s recommendations.
• Controlled conditioning and testing: The standard specifies a single set of environmental conditions for pre‑conditioning, conditioning and measurement (temperature and relative humidity are controlled), recognizing that electrostatic behaviour depends strongly on relative humidity.
  • Document gives specific controlled conditions for conditioning and measurement (temperature and % RH).
• Test equipment & setup: Defines required components such as the applied load, conductive electrode, counter electrode, insulative support plate, resistance measurement apparatus and environmental test chamber. Distinguishes between laboratory (qualification) measurements and on‑site acceptance testing.
• Test procedure and reporting: Describes the measurement method, repeatability/reproducibility considerations and required information for test reports.
• Exclusions/updates from previous edition: Classification of footwear as “electrostatic conductive” or “electrostatic dissipative” is removed; multiple environmental classes were removed in favor of one set of conditions; reference to IEC 61340-2-3 for counter electrode insertion was removed.

Applications and who uses this standard

• Footwear manufacturers - to qualify product electrical resistance during development and production.
• Quality control and testing laboratories - to perform accredited or in‑house qualification/acceptance testing.
• Electrostatic discharge (ESD) program managers & ESD engineers - to validate footwear performance in electronics manufacturing, cleanrooms, semiconductor or pharmaceutical environments.
• End users (manufacturers and facilities) - to perform acceptance testing of supplied footwear and periodic checks of in‑use footwear where wrist straps or tethers are impractical.

Use cases include verifying ESD footwear for personnel grounding on specified ESD flooring, ensuring consistent ESD protection in sensitive assembly areas, and documenting footwear electrical properties for ESD control programs.

Related standards

• IEC 61340 series (general electrostatics guidance)
• IEC 62631-3-x series (dielectric and resistive properties - volume/surface resistivity)

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61340-4-3 has been pr
