ISO/IEC 17025:2017·
Lab ID NKM/EQ-117
The Thin Film Oven performs the Thin Film Oven Test (TFOT), which simulates the short-term ageing (hardening) that bitumen undergoes during hot mixing and laying. Binder is aged as a thin film at 163 °C, then re-tested for penetration and viscosity to check its durability, per IS 9382.
What this equipment tests
- Short-term ageing of bitumen (TFOT) at 163 °C
- Loss on heating / mass change of binder
- Retained penetration & viscosity after ageing
Applicable Indian Standards
- IS 9382 — Thin film oven test for bitumen
- IS 73 — Paving bitumen — specification

Frequently asked questions
What does the thin film oven test simulate?
The hardening (ageing) that bitumen undergoes during hot-mix production and paving, so the binder's durability can be assessed.
At what temperature is TFOT run?
163 °C, per IS 9382.
