Electrostatics - Part 2-1: Measurement methods - Ability of materials and products to dissipate static electric charge
IEC 61340-2-1:2015 describes test methods for measuring the rate of dissipation of static charge of insulating and static dissipative 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 may 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, e.g. 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 may 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. This edition includes the following significant technical changes with respect to the previous edition: a) the first edition supported requirements in IEC TR 61340-5-1, but with the revision of IEC TR 61340-5-1 into an International Standard, this support is no longer required; references to IEC 61340-5-1 have been removed; b) the introduction gives additional information on when charge decay time measurements are appropriate, and the applications for which each of the two test methods are best suited; c) procedures for performance verification of measuring instruments for the corona charging method have been added. IEC 61340-2-1:2015 has the status of a horizontal standard in accordance with IEC Guide 108.
Elektrostatik - Teil 2-1: Messverfahren - Fähigkeit von Materialien und Erzeugnissen, elektrostatische Ladungen abzuleiten
Electrostatique - Partie 2-1: Méthodes de mesure - Capacité des matériaux et des produits à dissiper des charges électrostatiques
L'IEC 61340-2-1:2015 décrit les méthodes d'essai pour mesurer le taux de dissipation de charge statique des matériaux et des produits isolants et électrostatiquement dissipatifs. Elle comprend une description générique des méthodes d'essai et les procédures d'essai détaillées pour des applications spécifiques. Les deux méthodes d'essai pour mesurer le temps de décroissance de la charge, l'une utilisant la charge par effet de couronne et l'autre utilisant une plaque de métal chargée sont différentes et peuvent ne pas donner des résultats équivalents. Néanmoins, chaque méthode comporte une plage d'applications pour lesquelles elle est la plus adaptée. La méthode de la charge par effet de couronne convient à l'évaluation de l'aptitude des matériaux (p. ex.: textiles, emballages, etc.) à dissiper la charge de leurs propres surfaces. La méthode de la plaque de métal chargée convient à l'évaluation de l'aptitude des matériaux et objets (p. ex.: gants, doigtiers, outils à main, etc.) à dissiper la charge des objets conducteurs placés sur eux ou en contact avec eux. La méthode de la plaque de métal chargée peut ne pas convenir à l'évaluation de l'aptitude des matériaux à dissiper la charge de leurs propres surfaces. Outre son application générale, cette norme horizontale est également destinée à l'usage des comités d'études dans la préparation des normes, conformément aux principes établis dans le Guide 108 de l'IEC. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) la première édition prenait en charge les exigences de l'IEC TR 61340-5-1, mais avec la révision de l'IEC TR 61340-5-1 pour en faire une Norme internationale cette prise en charge n'est plus exigée; les références à l'IEC 61340-5-1 ont été supprimées; b) l'introduction donne des informations complémentaires sur le moment où les mesures du temps de décroissance de la charge sont appropriées, ainsi que les applications pour lesquelles chacune des deux méthodes d'essai est la plus adaptée; c) des procédures ont été ajoutées pour vérifier les performances des instruments de mesure dans le cadre de la méthode de charge par effet de couronne. Elle a le statut d'une norme horizontale conformément au Guide 108 de l'IEC.
Elektrostatika - 2-1. del: Merilne metode - Sposobnost materialov in izdelkov za odvajanje elektrostatičnega naboja
Ta del standarda IEC 61340 opisuje preskusne metode za merjenje hitrosti odvajanja statičnega naboja izolativnih materialov in izdelkov ter materialov in izdelkov, ki odvajajo statični naboj. Vključuje splošen opis preskusnih metod in podrobne preskusne postopke za posamezne uporabe.
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, npr. 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 v IEC Guide 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.

Ability of materials and products

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
