The ISO 7590 standard specifies the determination method of the total thickness and cover thickness of steel cord conveyor belts. The standard is applicable to the quality control and performance evaluation of steel cord conveyor belts, in particular to ensure the accuracy of the thickness of each layer of the conveyor belt through standardized measurement techniques. Test methods include the use of suitable instruments for the measurement of conveyor belts and the evaluation of conveyor belts of different structures to ensure that they meet the design requirements. This standard has important guiding significance for manufacturers, inspection agencies and related technicians to help optimize the design and performance of conveyor belts, improve their durability and safety during transportation.
