Heated Air Temperature Test Chamber For Electrical Insulation Materials ASTM D5423
This equipment is designed for testing material characteristics of wire type, skin type, plastic, rubber, and cloth. Equipped with a special ventilation regulator to maintain fresh air inside during heating operations.
The testing machine features a sophisticated air-displacement adjustment device and digital instrumentation including voltage meter, current meter, watt-hour meter, and timer for measuring air replacement rate. The horizontal circulatory air supply system with dual-side airflow regulators ensures internal temperature uniformity and stability.
- Studies rubber heated under rotary mode in fixed periods
- 1 day at 70℃ theoretically equivalent to 6 months of atmospheric exposure
- Motor-driven rotary disk with hot-air circulation system
- Ensures uniform temperature distribution
- Complies with ASTM, JIS, GB and other testing specifications
Accord with ASTM D5423-9(R2005)(Ⅱ-Type oven), ASTMD 5374-93(2005), UL-1581, GB, VDE, JIS, IEC standards.
Used to test material heat-resistance for polymer materials (plastics) and electrical insulation materials, including wire and cable sheathing, heat-shrinkable tubing, rubber, and PVC materials.

Formula per Japan JIS7212: N = 3590(X-Y)/(V×D×T)
- N = Number of air exchanges per hour
- X = Electricity consumption with ventilation (WH)
- Y = Electricity consumption without ventilation (WH)
- V = Volume (cm³)
- D = Air density (g/cm³)
- T = Temperature contrast between inside and outside
