Heat-resistant rubber cover conveyor belt
Thermal resistance requirements and test methods for coatings
1 Scope
This standard specifies the requirements for the determination of the relative degree of heat resistance of the rubber conveyor belt coating layer and its test method and specifies the coverage
The permissible range of hardness, elongation at break and tensile strength after exposure to the thermal environment.
This standard applies to cases where the thickness of the cover layer is equal to or greater than 4 mm.
This standard does not apply to conveyor belts as specified in ISO 21183-1 [1].
