Conveyor belts - Adhesion between constitutive elements - Test methods (ISO 252:2007)
ISO 252:2007 specifies two test methods, A and B, for determining the adhesion strength between constitutive elements of a conveyor belt, i.e. between plies and between covers and carcass. Basic test conditions are in conformity with ISO 36.
It is applicable to all types of construction of conveyor belting with the exception of belts containing steel cord reinforcement, and textile-reinforced belts with a full-thickness tensile strength of less than 160 N/mm. It is not suitable or valid for light conveyor belts as described in ISO 21183-1.
Fördergurte - Lagenhaftung zwischen den Bestandteilen - Prüfverfahren (ISO 252:2007)
Diese Norm legt zwei Prüfverfahren, A und B, zur Bestimmung des Trennwiderstands zwischen den Lagen sowie zwischen den Deckplatten und der Karkasse von Fördergurten fest. Die wesentlichen Bedingungen der Prüfung entsprechen ISO 36.
Die Norm ist auf alle Arten von Fördergurten anwendbar, mit Ausnahme von Gurten mit Stahlseileinlagen und von Gurten mit Textileinlage, deren Nennbruchkraft weniger als 160 N/mm beträgt. Sie ist nicht anwendbar oder gültig für leichte Fördergurte nach ISO 21183-1
ANMERKUNG Verfahren A oder Verfahren B können alter¬nativ angewendet werden, aber die berechneten Mittel¬werte für die Haftfestigkeit können für Verfahren A und Verfahren B unterschiedlich sein. Da auch beide Verfah¬ren nicht gleichwertig anwendbar sind für alle Gurtkon¬struktionen, sollte der Rat des Gurtherstellers eingeholt werden.
Courroies transporteuses - Adhérence entre éléments constitutifs - Méthodes d'essai (ISO 252:2007)
L'ISO 252:2007 spécifie deux méthodes d'essai, A et B, permettant de déterminer l'adhérence entre éléments constitutifs d'une courroie transporteuse, c'est-à-dire entre plis et entre revêtements et carcasse. Les conditions générales d'essai sont conformes à l'ISO 36.
Elle s'applique à tous types de construction de courroie transporteuse à l'exception des courroies à armature en câble d'acier, et des courroies à armature textile présentant une résistance à la rupture inférieure à 160 N/mm. Elle n'est pas applicable ou valable pour les courroies transporteuses légères décrites dans l'ISO 21183-1.

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 member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 252 was prepared by Technical Committee ISO/TC 41, Pulleys and belts (including veebelts),
Subcommittee SC 3, Conveyor belts.
This third edition of ISO 252 cancels and replaces ISO 252-1:1999, of which it constitutes a technical revision.
It also incorporates the Technical Corrigendum, ISO 252-1:1999/Cor. 1:2006.
