ISO 7622-1
Used for measuring the elongation behavior of steel cords used in conveyor belts. Significance and Use ISO 7622-1 is widely used for measuring the elongation characteristics of steel cords extracted from steel cord conveyor belts under controlled tensile loading conditions. The standard helps conveyor belt manufacturers study stretching behavior, dimensional stability, and traction performance of steel cord belts used in mining, ports, cement industries, steel industries, power plants, and long-distance bulk material handling systems. Elongation testing is important for conveyor system design, belt tension analysis, take-up calculations, and quality verification of steel cord constructions. Poor elongation behavior can result in belt sagging, slippage, structural instability, and operational performance issues during service. Presto Stantest offers advanced high-force tensile testing systems suitable for ISO 7622-1 testing with accurate elongation measurement, controlled loading speed, stable gripping arrangements, and software-based result analysis for laboratory and industrial testing applications.ISO 7622-1
Scope
This standard specifies a longitudinal traction test method for determining the elongation of steel cords removed from steel cord conveyor belts at defined load levels. The testing procedure applies only to steel cord conveyor belt constructions. During testing, extracted steel cord specimens are mounted in a tensile testing machine and loaded under controlled conditions while elongation values are measured at specified force levels. The method helps study the stretching characteristics, dimensional behavior, and tensile response of steel cord reinforcement used in conveyor belts. Multiple specimens are tested for comparative result analysis and reporting. Notes ISO 7622-1 is commonly followed for evaluating the elongation performance and tensile behavior of steel cord conveyor belts used in heavy-duty industrial conveying systems. Presto Stantest provides advanced tensile testing systems suitable for steel cord elongation testing with precise force control, accurate extensometer measurement, stable gripping fixtures, and software-based reporting solutions for research and quality control laboratories.
