Overview
SIST ISO 4195:2013 establishes standardized requirements and testing procedures for evaluating the heat resistance of rubber covers on conveyor belts. Developed by the International Organization for Standardization (ISO) and adopted by SIST, this standard specifically applies to conveyor belts with rubber covers at least 4 mm thick. It is primarily aimed at ensuring that conveyor belts maintain their essential properties-such as hardness, elongation at break, and tensile strength-after exposure to elevated temperatures. This standard does not apply to light conveyor belts as defined in ISO 21183-1.
Users of conveyor systems in industries such as mining, cement, steel, and power generation can rely on this standard to assure the durability and proper function of heat-resistant conveyor belt covers.
Key Topics
Applications
SIST ISO 4195:2013 is essential for industries where conveyor belts are exposed to high temperatures and must maintain mechanical integrity and performance, including:
- Mining and Bulk Material Handling: Ensures conveyor belts transporting hot minerals or materials retain strength and performance.
- Power Generation: Supports systems moving heated ash or slag.
- Cement and Steel Manufacturing: Protects conveyor belts used for conveying hot clinker and similar materials.
- Chemical Processing: Helps select appropriate belt covers where heat exposure is routine.
By conforming to this standard, manufacturers and users can:
- Assure reliable performance under heat-stressed conditions
- Reduce the risk of downtime and belt failure
- Specify products based on standardized, internationally recognized criteria
