Conveyor belts — Adhesion between constitutive elements — Test methods (ISO 252:2023)

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 252:2023)

Dieses Dokument 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.
Es 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. Es ist nicht anwendbar oder gültig für leichte Fördergurte nach ISO 21183 1 [1].
ANMERKUNG   Verfahren A oder Verfahren B können alternativ angewendet werden, aber die berechneten Mittelwerte für die Haftfestigkeit können für Verfahren A und Verfahren B unterschiedlich sein. Da auch beide Verfahren möglicherweise nicht gleichwertig anwendbar sind für alle Gurtkonstruktionen, sollte der Rat des Gurtherstellers eingeholt werden.

Courroies transporteuses — Adhérence entre éléments constitutifs -— Méthodes d'essai (ISO 252:2023)

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.

Naprave za kontinuirni transport - Trakovi tračnih transporterjev - Sprijetost osnovnih sestavnih elementov - Preskusne metode (ISO 252:2023)

Standard ISO 252:2007 določa dve preskusni metodi, in sicer metodo A in B, za določevanje sprijetosti osnovnih sestavnih elementov trakov tračnih transporterjev, tj. sprijetosti posameznih plasti ter sprijetosti pokrova in trupa. Osnovni pogoji preskušanja so v skladu s standardom ISO 36.
Uporablja se za vse vrste konstrukcij trakov tračnih transporterjev z izjemo trakov z ojačitvenim železnim kablom in trakove, ojačane s tekstilnim vložkom, z natezno trdnostjo, ki je pri polni debelini manjša od 160 N/mm. Ta standard se ne uporablja oziroma ni veljaven za lahke trakove tračnih transporterjev, opisane v standardu ISO 21183-1.
