This part of IEC 61340 describes test methods for measuring the rate of dissipation of static charge of insulating and static materials and products.
It includes a generic description of test methods and detailed test procedures for specific applications.
The two test methods for measuring charge decay time, one using corona charging and one using a charged metal plate are different and might not give equivalent results. Nevertheless, each method has a range of applications for which it is best suited. The corona charging method is suitable for evaluating the ability of materials, for example textiles, packaging, etc., to dissipate charge from their own surfaces. The charged metal plate method is suitable for evaluating the ability of materials and objects such as gloves, finger cots, hand tools, etc. to dissipate charge from conductive objects placed on or in contact with them. The charged plate method might not be suitable for evaluating the ability of materials to dissipate charge from their own surfaces.
In addition to its general application, this horizontal standard is also intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications. The contents of this horizontal standard shall not apply unless specifically referred to or included in the relevant publications.

Preskusni metodi za merjenje časa odvajanja naboja, pri čemer ena uporablja koronsko polnjenje in druga napolnjeno kovinsko ploščo, se med seboj razlikujeta ter morda ne bosta zagotovili enakovrednih rezultatov. Vendar je mogoče vsako metodo uporabiti na različnih področjih, za katere je najprimernejša. Metoda koronskega polnjenja je primerna za oceno sposobnosti materialov, na primer tekstilij, embalaž ipd., za odvajanje naboja z lastnih površin. Metoda napolnjene kovinske plošče je primerna za oceno sposobnosti materialov in predmetov, kot so rokavice, naprstne rokavice, ročna orodja ipd., za odvajanje naboja s prevodnih predmetov, postavljenih nanje ali v stiku z njimi. Metoda polnjene plošče morda ni primerna za oceno sposobnosti materialov za odvajanje naboja z lastnih površin.
Poleg veljavnosti na svojem splošnem področju je ta horizontalni standard namenjen tehničnim odborom za pripravo standardov v skladu z načeli vodila IEC 108.
Ena od pristojnosti tehničnih odborov je, da med pripravo publikacij uporabljajo horizontalne standarde, kadar je to primerno. Vsebine tega horizontalnega standarda se ne sme uporabljati, razen če je izrecno navedena ali zajeta v ustreznih publikacijah.

Overview
SIST EN 61340-2-1:2016/A1:2022 is a European standard published by CLC that specifies measurement methods to assess the ability of materials and products to dissipate static electric charge. It forms part of the IEC 61340 series focused on electrostatics, providing standardized procedures to evaluate static charge dissipation performance. This amendment updates the original 2015 standard, reflecting contemporary technical developments and clarifications.
The standard is essential for industries and laboratories working with static dissipation in materials such as textiles, packaging, gloves, tools, and other products prone to electrostatic charge accumulation. Proper static control is vital for preventing damage to sensitive electronic components, ensuring safety in explosive environments, and maintaining product quality.
Key Topics
Test Methods for Charge Dissipation
SIST EN 61340-2-1:2016/A1:2022 describes two primary test methods for measuring charge decay time:- Corona Charging Method: Appropriate for assessing how materials-such as textiles and packaging-dissipate static charge from their own surfaces. This method involves depositing charge via corona discharge and measuring decay over time.
- Charged Metal Plate Method: Suitable for evaluating materials and objects that dissipate charge from conductive objects placed on or contacting them, including gloves, finger cots, and hand tools. This method may not be reliable for charge dissipation from a material’s own surface.
Charge Decay Time Measurement
The standard details the calculation and significance of charge decay time (t_sd), with specifications on the fractions of initial voltage used for measurements (1/e and 10%). It also explains the possible occurrence of non-zero offset voltages during decay.Test Equipment and Safety
Mandatory compliance with safety standards IEC 61010-1 and IEC 61010-2-030 for electrical equipment used in the testing procedures is enforced. The document emphasizes risk assessments due to use of high-voltage power supplies.Material Homogeneity and Measurement Reliability
The standard highlights that some materials may be electrically non-homogeneous, leading to unreliable results from simple resistance or resistivity measurements. In these cases, direct measurements of static charge dissipation are recommended.Effect of Capacitance in Tools Testing
Observations on charge decay waveforms underline how capacitance effects between tools and hands can affect test results, requiring interpretation adjustments.
Applications
Electrostatic Control in Manufacturing
This standard is fundamental in environments where controlling static electricity is crucial to prevent damage of electronic components, e.g., assembly lines for semiconductors and printed circuit boards.Material Selection for Static Dissipative Properties
Textile, packaging, and glove manufacturers use these test methods to quantify the static dissipation properties of their products to improve user safety and product compliance.Quality Assurance and Product Certification
Organizations apply EN 61340-2-1 methods to certify products meet prescribed electrostatic dissipation characteristics required for safe handling in sensitive or explosive atmospheres.Technical Committees and Standards Development
As a horizontal standard, this document assists various technical committees by providing harmonized test methods applicable across multiple standards that require assessment of static charge dissipation.

AMENDMENT 1
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, u
