Standards
- ASTM D1790: Brittleness temperature testing for plastic sheeting under impact.
- ASTM D1593M: Low-temperature flexibility of coated fabrics.
- JIS K6545: Flexing endurance assessment for leather and synthetic materials in cold climates.
Product Advantages
- Extreme Temperature Performance: Tests materials from ambient to -60°C, simulating Arctic or high-altitude conditions.
- Dual Fixture Options: 6-station (1.5Hz) or 12-station (100 cycles/min) configurations for versatile testing protocols.
- Precision Cooling: R404A refrigerant and France Taikang compressors achieve -60°C in 60 minutes with ±0.5°C accuracy.
- Enhanced Safety: Thermal shutdown, overload protection, and vacuum-insulated windows ensure operator safety.
- Modular Design: Interchangeable V-shaped fixtures (40° angle, 6.4mm radius) accommodate footwear uppers, gloves, and textiles.
- Energy Efficiency: 4kW power consumption with hard foam/glass wool insulation minimizes operational costs.
Product Features
- Stainless Steel Construction: Corrosion-resistant 304-grade steel chamber with dual-layer vacuum windows.
- Omron Controller: Programmable temperature ramps, cycle counts, and hold times with LCD data display.
- Rapid Cooling System: -30°C achieved in 45 minutes; -60°C in 60 minutes via cascading refrigeration.
- Safety Suite: Leakage protection, over-temperature alerts, and 5-minute compressor delay for longevity.
- Illuminated Chamber: 5W LED lighting for clear sample observation during testing.
- Multi-Station Flexing: 12 clamps with 22.5° bending angle or 6 clamps with 40° V-shaped fixtures.
