Loss on Heating Thin Film Oven
Product Code : EL-BTLE-10432
Loss on Heating Thin Film Oven (code EL-BTLE-10432) is a hot air oven for the loss on heating and thin film oven tests on bitumen, which call for a working temperature of 163 °C ± 1 °C. A detachable metal shaft, turned at 5-6 RPM by a reduction gear fitted outside, rotates the samples, the 304 grade stainless steel interior is surrounded by mineral/blanket insulation, and a toughened glass window shows the material without upsetting the chamber temperature.

What Is the Loss on Heating Thin Film Oven Used For?
Bitumen hardens when it is heated in thin layers during mixing and laying, and these tests imitate that ageing in the laboratory. Weighed samples, either in containers for loss on heating or spread as a thin film in flat pans, are set on the shelf turned by the shaft and held at 163 °C ± 1 °C for the set period. They are then cooled and reweighed to find the loss in mass, and properties such as penetration or viscosity of the residue are compared with those of the original binder. The standards listed are EN 12607-2, BS 2000-460-2, EN 13303, ASTM D6/D6M, ASTM D1754/D1754M, AASHTO T47 and AASHTO T179.
What to Specify When Ordering
- Quantity — the number of ovens required.
- Temperature controller — whether the digital temperature controller cum indicator with alarm facility is wanted.
Frequently Asked Questions
What temperature does the thin film oven work at?
The tests need a working temperature of 163 °C ± 1 °C, as required by IS and ASTM, and the oven's ventilation keeps its outer surface from burning even with the chamber at 200 °C.
How are the samples rotated?
A reduction gear mounted outside the cabinet turns a vertical shaft at 5-6 RPM, and the detachable metal shaft serves both the loss on heating and the thin film oven tests.
Can the samples be watched during a test?
Yes. A toughened glass view window allows the material to be observed without opening the door and disturbing the temperature condition of the chamber.
What is the chamber made of?
The interior is 304 grade stainless steel sheet with a polished/hairline finish, which resists corrosion, and mineral/blanket insulation surrounds it to limit heat loss.
Is a digital controller available?
A digital temperature controller cum indicator with alarm facility can be fitted on customer request, working with the coil shaped and tubular air heaters on the side or back of the oven.
Which test methods is the oven listed for?
For this oven the standards listed are EN 12607-2, BS 2000-460-2, EN 13303, ASTM D6/D6M, ASTM D1754/D1754M, AASHTO T47 and AASHTO T179.
