Job Application
The Rolling Thin Film Oven complies with international standards including ASTM D2872, AASHTO T240, CNR N.54, EN 12607-1, and IS 15799-2008. It is designed to determine the resistance of bituminous binders to hardening from heat and air through the Rolling Thin Film Oven Test. This unit simulates the short-term aging that occurs during the mixing of binders with aggregates and the finishing of bituminous layers.
Salient Features:
- Double-walled, electrically heated oven with high-density glass wool insulation.
- Over-temperature and door open automatic safety switches.
- High resistance glass door with an uninterrupted view of the interior.
- Armored heating resistance and a digital electronic thermo-regulator operating in PID mode.
- Rotating shelf with minimal air resistance, capable of holding up to eight sample containers.
- Equipped with a digital flow meter, air flow regulator, and cooling fan.
- Includes pilot lamps, a 2-meter cord, and power plug.
Details of Apparatus:
- Rotating Shelf: Metal vertical circular carriage with a diameter of 304.8 mm, rotating at 5-60 RPM, accommodating up to eight sample containers.
- Sample Containers: Heat-resistant glass with a 64 mm diameter and 139.7 mm depth.
- Thermometer: ASTM 13C thermometer with calibration traceability to National Standards (optional).
