The GESTER Button Snap Tester GT-C09 is a critical safety and quality assurance instrument designed to determine the holding or breaking strength of buttons, snap fasteners, push-buttons, rivets, and small accessories attached to garments—particularly infant and children’s clothing. By conducting uniform vertical tensile tests, the GT-C09 helps garment manufacturers prevent small component detachment, mitigating infant swallowing and choking hazards in compliance with strict international consumer safety laws.  Engineered with a high-precision force gauge, rugged mounting frame, and standardized calibration weight, the GT-C09 guarantees repeatable holding force measurements according to 16 CFR 1500, ASTM D4846, and ASTM PS79.

The GESTER GT-C39B Zipper Rotation Testing Machine is a highly specialized mechanical tester engineered explicitly to measure the torsional strength, twist tolerance, and torque degradation of zipper sliders and pullers. Supporting advanced interactive operational modes—including twist-off, constant angle, and constant load—it isolates the exact mechanical failure thresholds of slider bodies and pull-tab joints. Equipped with a touch-screen control panel and heavy-duty stainless steel fixtures, the GT-C39B ensures precise data logging to satisfy strict hardware-focused safety benchmarks including ASTM D2061, 16CFR 1500.51-53, and EN 16732.
