Q1: What core materials can be tested on the GESTER GT-C34A?
A: The GT-C34A is engineered for a wide variety of flexible and rigid sheet materials, including automotive interior parts (seat covers, carpets, headliners, door trims), plastic sheets and films (per ASTM D5132), synthetic leather, rubber compounds, and woven/knitted textiles (per FZ/T 01028 and GB/T 20953).
Q2: How does the GT-C34A satisfy OEM-specific requirements like General Motors GMW3232?
A: GMW3232 mandates strict U-frame dimensions, 38mm flame height calibration, and standardized burning distance tracking. The GT-C34A provides exact physical tolerances, draught-free airflow design, and 0.1s digital timing accuracy to fully comply with GMW3232 and FMVSS 302 testing protocols.
Q3: Does the GT-C34A support horizontal flammability testing for textiles?
A: Yes. In addition to automotive plastics and interiors, the GT-C34A strictly conforms to FZ/T 01028 (Textiles - Determination of burning behavior - Horizontal method) and GB/T 20953, making it suitable for evaluating horizontal flame spread across woven, knitted, and coated fabrics.
Q4: How are thin films or easily melting materials supported during testing?
A: For materials that sag or melt when exposed to heat (such as thin plastic films, light textiles, or soft foams), thin heat-resistant stainless steel support wires can be mounted across the U-frame as specified in GB/T 8410 and FMVSS 302.
