Low Temperature Bending Tester
The Low Temperature Bending Tester is designed for evaluating a material’s flexibility, durability, and resistance to cracking under extreme cold conditions. By recreating environments from everyday winter climates to severe Arctic temperatures as low as –60°C, the tester helps manufacturers understand how plastics, coated fabrics, synthetic leather, footwear materials, gloves, and technical textiles perform when exposed to low-temperature mechanical stress.
This instrument is widely used in R&D laboratories, product quality inspection, and material certification centers across multiple industries.
Compliant Testing Standards
The tester meets several recognized international test methodologies:
| Standard | Description |
|---|---|
| ASTM D1790 | Brittleness temperature test for plastic sheeting under impact |
| ASTM D1593M | Low-temperature flexibility test for coated fabrics |
| JIS K6545 | Flexing endurance method for leather and synthetic materials in cold environments |
