The GESTER GT-C39A Zipper Fatigue Tester is the industry-standard equipment for determining the reciprocation resistance and long-term durability of slide fasteners. By driving the zipper through continuous back-and-forth cycles under lateral and longitudinal tension, it evaluates physical wear, fluffing, joint displacement, and connector failure. Equipped with an LCD counter and automated machine stop, the GT-C39A provides a highly accurate, cost-effective testing baseline compliant with global standards like BS 3084, EN 16732, ASTM D2061 and SATRA TM50.
Kinetic Energy tester is used to detect the maximum kinetic energy generated by the fired bullets of Projectile toys or the launched bows. It meets standards: ISO 8124-1, GB6675-2, EN-71-1, ASTM F963.
