Textile conveyor belts - Full thickness tensile strength, elongation at break and elongation at the reference load - Test methods
ISO 283:2007 specifies a test method for the determination of the full thickness tensile strength in the longitudinal direction and the elongation at the reference force and breaking point of conveyor belts having a textile carcass. The method can also be used for the determination of full thickness tensile strength in the transverse direction and the elongation at the breaking point, for use when the manufacturer is requested by the purchaser to state values for these properties. It is not suitable or valid for light conveyor belts as described in ISO 21183-1.

Le présent document fixe et décrit une méthode d'essai pour mesurer par traction la résistance et l'allongement à la rupture des courroies transporteuses à carcasse textile en pleine épaisseur jusqu'à une résistance de 2 500 N/mm. Les courroies transporteuses légères concernées par la NF EN 873 et celles à carcasses métalliques ne rentrent pas dans le domaine d'application du présent document.
<p>ISO 283:2015 specifies a test method for the determination of the full thickness tensile strength in the longitudinal direction and the elongation at the reference force and breaking point of conveyor belts having a textile carcass. The method can also be used for the determination of full thickness tensile strength in the transverse direction and the elongation at the breaking point, for use when the manufacturer is requested by the purchaser to state values for these properties.</p> <p>ISO 283:2015 is not suitable or valid for light conveyor belts as described in ISO 21183‑1.</p>
