Conveyor belts - Electrical conductivity - Specification and test method (ISO 284:2003)
ISO 284:2003 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 may be developed during service use.
ISO 284:2003 is not suitable or applicable to light conveyor belts as described by EN 873, the static electrical properties of which are measured by EN 1637.
Fördergurte - Elektrische Leitfähigkeit - Spezifikation und Prüfverfahren (ISO 284:2003)
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 ent-stehen können.
Diese Internationale Norm ist nicht geeignet oder anwendbar für leichte Fördergurte, die in EN 873 [1] beschrieben sind. Deren elektrische Eigenschaften werden nach EN 1637 [2] gemes-sen.
Courroies transporteuses - Conductibilité électrique - Spécification et méthode d'essai (ISO 284:2003)
L'ISO 284:2003 spécifie la résistance électrique maximale que doit présenter une courroie transporteuse, ainsi que la méthode d'essai de mesure correspondante.
Cet essai est destiné à s'assurer que la courroie est suffisamment conductrice pour écouler les charges d'électricité statique qui pourraient s'y former en service.
L'ISO 284:2003 ne convient pas et n'est pas applicable aux courroies transporteuses légères décrites dans l'EN 873, dont les propriétés d'électricité statique sont mesurées conformément à l'EN 1637.

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 International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the me
