Conveyor belts - Laboratory scale flammability characteristics - Requirements and test method (ISO 340:2022)

This document specifies a method for assessing, on a small scale, the reaction of a conveyor belt to an ignition flame source. It is applicable to conveyor belts having a textile carcass as well as steel cord conveyor belts.

Fördergurte - Brandverhalten unter Laborbedingungen - Anforderungen und Prüfverfahren (ISO 340:2022)

Dieses Dokument legt ein Prüfverfahren im kleinen Maßstab zur Bewertung des Verhaltens eines Fördergurts fest, der einer Flamme als Zündquelle ausgesetzt ist. Es ist sowohl bei Textil- als auch bei Stahlseilförder¬gurten anwendbar.
WARNUNG — Dieses Prüfverfahren ist nicht dazu bestimmt, die Feuergefährlichkeit eines bestimmten Produkts zu beurteilen. Die Ergebnisse können bei der Abschätzung der Entflammbarkeitsgefahr helfen, aber sollten nicht als alleinstehender Nachweis verwendet werden, ob ein Produkt oder Werk¬stoff sicher ist.

Courroies transporteuses - Caractéristiques d'inflammabilité d'échelle de laboratoire - Exigences et méthode d'essai (ISO 340:2022)

Le présent document spécifie une méthode permettant d’évaluer, à petite échelle, la réaction d’une courroie transporteuse à une source d’allumage avec flamme. Il est applicable aux courroies transporteuses à carcasse textile de même qu’aux courroies transporteuses à câble acier.

Naprave za kontinuirni transport - Trakovi tračnih transporterjev - Laboratorijska lestvica lastnosti gorljivosti (vnetljivosti) - Zahteve in preskusna metoda (ISO 340:2022)

Ta dokument določa metodo za ocenjevanje (v majhnem merilu) odziva trakov tračnih transporterjev na vir vžiga, tj. odprti plamen. Uporablja se za trake tračnih transporterjev, ki imajo trup iz tekstila, in transporterje z jeklenim vložkom.
