The ISO 4195 standard specifies the heat resistance requirements and test methods for conveyor belts with heat resistant rubber overlays. The standard aims to assess the performance of conveyor belt overlays in high temperature environments to ensure their Reliability and durability under high temperature conditions. Test methods include exposing the sample to specified high temperature conditions, measurement of changes in its Physical and Mechanical Properties such as tensile strength, Tearing strength and Hardness etc. Through these tests, the suitability and safety of conveyor belt overlays in high temperature environments can be determined.
