Conveyor belts - Electrical conductivity - Specification and test method (ISO 284:2012)

This International Standard specifies the maximum electrical resistance of a conveyor belt and the corresponding test method. The test is intended to ensure that the belt is sufficiently conductive to avoid the accumulation of electrical static charge which can be developed during service use. This International Standard is not suitable or applicable to light conveyor belts as described in ISO 21183-1, the static electrical properties of which are measured by ISO 21178.

Fördergurte - Elektrische Leitfähigkeit - Spezifikation und Prüfverfahren (ISO 284:2012)

Diese Internationale Norm legt den größten elektrischen Widerstand eines Fördergurtes und das entsprechende Prüfverfahren fest.
Mit der Prüfung soll sichergestellt werden, dass der Gurt genügend leitfähig ist, um eine Erhöhung elektrostatischer Aufladungen zu verhindern, die während des Betriebes entstehen können.
Diese Internationale Norm ist nicht geeignet oder anwendbar für leichte Fördergurte, die in ISO 21883 1 [1] beschrieben sind. Deren elektrische Eigenschaften werden nach ISO 21178 [2] gemessen.

Courroies transporteuses - Conductibilité électrique - Spécification et méthode d'essai (ISO 284:2012)

L'ISO 284:2012 spécifie la résistance électrique maximale que doit présenter une courroie transporteuse, ainsi que la méthode d'essai correspondante.
Cet essai a pour objectif de s'assurer que la courroie est suffisamment conductrice afin d'éviter l'accumulation des charges d'électricité statique qui pourraient s'y former en service.
L'ISO 284:2012 n'est pas appropriée ou applicable pour les courroies transporteuses légères décrites dans l'ISO 21183‑1, dont les propriétés d'électricité statique sont mesurées par l'ISO 21178.

Naprave za kontinuirni transport - Trakovi tračnih transporterjev - Električna prevodnost - Specifikacija in preskusna metoda (ISO 284:2012)

Ta mednarodni standard določa največjo električno upornost trakov tračnih transporterjev in ustrezno preskusno metodo. Preskus je namenjen zagotavljanju zadostne prevodnosti traku, da se prepreči akumulacija električnega statičnega naboja, ki lahko nastane med uporabo. Ta mednarodni standard ni primeren ali uporaben za lahke trakove tračnih transporterjev, ki so opisani v standardu ISO 21183-1; njihove statične električne lastnosti se merijo z uporabo standarda ISO 21178.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International

Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft Internatio
