Testing hydraulic seals involves pressure cycling, temperature soaking, and wear simulation. Leakage rate, extrusion resistance, and friction are measured. Standards like ISO 7986 and ASTM D5474 guide testing protocols. Accelerated life testing predicts field performance. Manufacturers use finite element analysis (FEA) to optimize seal geometry before physical testing, reducing develo... https://globalsealstech.com/hydraulic-seals/
