The global catalyst aging testing market encompasses the sector dedicated to assessing the long-term performance, durability, and deactivation behavior of catalysts used in automotive exhaust systems, petrochemical operations, and industrial chemical production. Aging tests evaluate catalyst performance under prolonged thermal, chemical, and mechanical stresses, ensuring compliance with emissions and efficiency standards. These tests are especially critical in automotive applications, where catalysts must meet stringent regulations such as EURO 7 and other global norms, driving demand for accurate aging assessments.
